Reel Size : 0178
Q’ty : 2000 pcs./Reel
Packaging : Embossed Carrier Taping
■ Packaging state
■Storage Conditions
● Package : Normal temperature (–5 to 35 °C), normal humidity (85 %RH max.), shall not be exposed to
direct sunlight and harmful gases and care should be taken so as not to cause dew.
● Operating Temperature : –40 to +85 °C
■Storage Period
● Solderability may be reduced due to the conditions of high temperature and high humidity which causes the oxidation
of tin-plated terminals. Even if storage conditions are within specifi ed limits, solderability may be reduced with the
passage of time. Therefore, please control the storage conditions and try to use the product within 6 months of receipt.

Coil type EMI Filters
The following are precautions for individual products.Please also refer to the common precautions for Noise Suppression
Device shown on this catalog.
1. Operation range and environments
1 These products are designed and manufactured for general and stan dard use in general elec tron ic
equipment (e.g. AV equipment, home electric ap pli anc es, office equipment, information and com mu ni ca tion
equipment)
2 These products are not intended for use in the following special conditions. Be fore using the products, care ful ly check
the effects on their quality and performance, and determine whether or not they can be used.
• In liquid, such as water, oil, chemicals, or organic solvent
• In direct sunlight, outdoors, or in dust
• In salty air or air with a high concentration of corrosive gas, such as Cl2, H2S, NH3, SO2, or NO2
• In an environment where these products cause dew condensation
2. Handling
1 Do not bring magnets or magnetized materials close to the product. The infl uence of their magnetic fi eld can
change the inductance value.
2 Do not apply strong mechanical shocks by either dropping or collision with other parts.
Excessive schock can damage the part.
3. Land pattern design
1 Please refer to the recommended land pattern for each type shown on the datasheet.
2 In case of refl ow soldering, consider the layout because taller components close to EMI fi lters tend to block
thermal conduction.
4. Mounting
1 Avoid excessive placement force.
2 Do not bend or twist the PWB after mounting the part.
5. Cleaning
1 Do not use acid or alkali agents. Some cleaning solvents may damage the part.
Confi rm by testing the reliability in advance of mass production.
2 If Ultrasonic cleaning is used, please confi rm the reliability in advance.
It is possible that combined resonance of component and PWB and cavitation can cause an abnormal vibration
mode to exist causing damage.
