Before a solderability test is carried out, terminals are subjected to accelerated ageing (to IEC 60068-2-2:2007, test Ba: 4 h exposure to dry heat at 155 C). Since the ageing temperature is far higher than the upper category temperature of the capacitors, the terminal wires should be cut off from the capacitor before the ageing procedure to prevent the solderability being impaired by the products of any capacitor decomposition that might occur.

Long exposure to temperatures above this type-related temperature limit can lead to changes in the plastic dielectric and thus change irreversibly a capacitor's electrical characteristics. For short exposures (as in practical soldering processes) the heat load (and thus the possible effects on a capacitor) will also depend on other factors like: Pre-heating temperature and time Forced cooling immediately after soldering Terminal characteristics: diameter, length, thermal resistance, special configurations (e.g. crimping) Height of capacitor above solder bath Shadowing by neighboring components Additional heating due to heat dissipation by neighboring components Use of solder-resist coatings Please read Cautions and warnings and Important notes at the end of this document. Page 12 of 23 B32021 ... B32026 Y2 / 300 V AC The overheating associated with some of these factors can usually be reduced by suitable countermeasures. For example, if a pre-heating step cannot be avoided, an additional or reinforced cooling process may possibly have to be included. Recommendations As a reference, the recommended wave soldering profile for our film capacitors is as follows: Please read Cautions and warnings and Important notes at the end of this document. Page 13 of 23 B32021 ... B32026 Y2 / 300 V AC Body temperature should follow the description below: MKP capacitor During pre-heating: Tp 110 C During soldering: Ts 120 C, ts 45 s MKT capacitor During pre-heating: Tp 125 C During soldering: Ts 160 C, ts 45 s When SMD components are used together with leaded ones, the film capacitors should not pass into the SMD adhesive curing oven. The leaded components should be assembled after the SMD curing step. Leaded film capacitors are not suitable for reflow soldering. In order to ensure proper conditions for manual or selective soldering, the body temperature of the capacitor (Ts) must be 120 C. One recommended condition for manual soldering is that the tip of the soldering iron should be <360 C and the soldering contact time should be no longer than 3 seconds. For uncoated MKT capacitors with lead spacings 10 mm (B32560/B32561) the following measures are recommended: pre-heating to not more than 110 C in the preheater phase rapid cooling after soldering Please refer to our Film Capacitors Data Book in case more details are needed. Application note A Y capacitor to be connected between AC lines and the Frame Ground (FG) has an effect of emitting common mode current to the FG.Leak current corresponding in frequency and voltage to the AC power supply flows in the Y capacitor. As the capacity of a Y capacitor grows, leak current also increases. This can cause electric shock. Therefore, UL and other safety standards restrict the capacity so that the amount of leak current does not exceed a certain level. Usually, two Y capacitors are used, as shown in Figure below. As AC lines are connected with capacitors, they are effective in reducing differential mode noises. In particular, they are effective for high frequency ranges of 8 to 10 MHz.

B32026 Y2 / 300 V AC Cautions and warnings Do not exceed the upper category temperature (UCT). Do not apply any mechanical stress to the capacitor terminals. Avoid any compressive, tensile or flexural stress. Do not move the capacitor after it has been soldered to the PC board. Do not pick up the PC board by the soldered capacitor. Do not place the capacitor on a PC board whose PTH hole spacing differs from the specified lead spacing. Do not exceed the specified time or temperature limits during soldering. Avoid external energy inputs, such as fire or electricity. Avoid overload of the capacitors. Consult us if application is with severe temperature and humidity condition. There are no serviceable or repairable parts inside the capacitor. Opening the capacitor or any attempts to open or repair the capacitor will void the warranty and liability of TDK Electronics. Please note that the standards referred to in this publication may have been revised in the meantime. The table below summarizes the safety instructions that must always be observed. A detailed description can be found in the relevant sections of the chapters "General technical information" and "Mounting guidelines". Topic Safety information Storage conditions Make sure that capacitors are stored within the specified range of time, temperature and humidity conditions. Avoid external energy, such as fire or electricity (passive flammability), avoid overload of the capacitors (active flammability) and consider the flammability of materials. Do not exceed the tested ability to withstand vibration. The capacitors are tested to IEC 60068-2-6:2007. TDK Electronics offers film capacitors specially designed for operation under more severe vibration regimes such as those found in automotive applications.

B32026 Y2 / 300 V AC Topic Safety information Soldering Do not exceed the specified time or temperature limits during soldering. Use only suitable solvents for cleaning capacitors. When embedding finished circuit assemblies in plastic resins, chemical and thermal influences must be taken into account. Caution: Consult us first, if you also wish to embed other uncoated component types! Cleaning Embedding of capacitors in finished assemblies Reference chapter "Mounting guidelines" 1 "Soldering" 2 "Cleaning" 3 "Embedding of capacitors in finished assemblies" Design of our capacitors Our EMI capacitors use polypropylene (PP) film metalized with a thin layer of Zinc (Zn). The following key points have made this design suitable to IEC/UL testing, holding a minimum size. Overvoltage AC capability with very high temperature Endurance test of IEC 60384-14:2013 (4th edition) / UL 60384-14:2014 (2nd edition) must be performed at 1.25 x VR at maximum temperature, during 1000 hours, with a capacitance drift less than 10%. Higher breakdown voltage withstanding if compared to other film metallizations, like Aluminum. IEC 60384-14:2013 (4th edition) / UL 60384-14:2014 (2nd edition) establishes high voltage tests performed at 4.3 x VR 1 minute, impulse testing at 2500 V for C = 1 F and active flammability tests. Damp heat steady state: 40 C/ 93% RH / 56 days. (without voltage or current load) Effect of humidity on capacitance stability Long contact of a film capacitor with humidity can produce irreversible effects. Direct contact with liquid water or excess exposure to high ambient humidity or dew will eventually remove the film metallization and thus destroy the capacitor. Plastic boxed capacitors must be properly tested in the final application at the worst expected conditions of temperature and humidity in order to check if any parameter drift may provoke a circuit malfunction. In case of penetration of humidity through the film, the layer of Zinc can be degraded, specially under AC operation (change of polarity), accelerated by the temperature, provoking an increment of the serial resistance of the electrode and eventually a reduction of the capacitance value. For DC operation, the parameter drift is much less. Plastic boxes and resins can not protect 100% against humidity. Metal enclosures, resin potting or coatings or similar measures by customers in their applications will offer additional protection against humidity penetration.

(Sinusformige) Wechselspannung Page 21 of 23 Important notes The following applies to all products named in this publication: 1. Some parts of this publication contain statements about the suitability of our products for certain areas of application. These statements are based on our knowledge of typical requirements that are often placed on our products in the areas of application concerned. We nevertheless expressly point out that such statements cannot be regarded as binding statements about the suitability of our products for a particular customer application. As a rule, we are either unfamiliar with individual customer applications or less familiar with them than the customers themselves. For these reasons, it is always ultimately incumbent on the customer to check and decide whether a product with the properties described in the product specification is suitable for use in a particular customer application. 2. We also point out that in individual cases, a malfunction of electronic components or failure before the end of their usual service life cannot be completely ruled out in the current state of the art, even if they are operated as specified. In customer applications requiring a very high level of operational safety and especially in customer applications in which the malfunction or failure of an electronic component could endanger human life or health (e.g. in accident prevention or lifesaving systems), it must therefore be ensured by means of suitable design of the customer application or other action taken by the customer (e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by third parties in the event of malfunction or failure of an electronic component. 3. The warnings, cautions and product-specific notes must be observed. 4. In order to satisfy certain technical requirements, some of the products described in this publication may contain substances subject to restrictions in certain jurisdictions (e.g. because they are classed as hazardous). Useful information on this will be found in our Material Data Sheets on the Internet (www.tdk-electronics.tdk.com/material). Should you have any more detailed questions, please contact our sales offices. 5. We constantly strive to improve our products. Consequently, the products described in this publication may change from time to time. The same is true of the corresponding product specifications. Please check therefore to what extent product descriptions and specifications contained in this publication are still applicable before or when you place an order. We also reserve the right to discontinue production and delivery of products. Consequently, we cannot guarantee that all products named in this publication will always be available. The aforementioned does not apply in the case of individual agreements deviating from the foregoing for customer-specific products. 6. Unless otherwise agreed in individual contracts, all orders are subject to our General Terms and Conditions of Supply. Page 22 of 23 Important notes 7. Our manufacturing sites serving the automotive business apply the IATF 16949 standard. The IATF certifications confirm our compliance with requirements regarding the quality management system in the automotive industry. Referring to customer requirements and customer specific requirements ("CSR") TDK always has and will continue to have the policy of respecting individual agreements. Even if IATF 16949 may appear to support the acceptance of unilateral requirements, we hereby like to emphasize that only requirements mutually agreed upon can and will be implemented in our Quality Management System. For clarification purposes we like to point out that obligations from IATF 16949 shall only become legally binding if individually agreed upon. 8.
