□Precautions for Product Safety
1. The products are designed and produced for general electronic devices applications.
User must contact our sales in-charge before using our products, if there is a risk to occur critical
issues, such as casualties due to breakdown or malfunction of devices from application on products
demanding high reliability or other safety devices, also for complicated products such as
medical equipment, transportation equipment, an aircraft/spacecraft, an atomic energy
controller, a fuel controller, automobile equipment, military equipment, disaster/crime preventive
equipment.
2. The products are designed for use in the standard environment. Do not use products in specific
environment that can affect a product performance. If you need to use products in the
following conditions, please contact our sales in-charge in advance.
①Various types of liquid including water, oil, organic solvent and other chemicals.
②Direct sunlight, outdoors, or atmosphere with an amount of dusts.
③An amount of corrosive gases such as sea breeze, Cl2, H2S, NH3, SO2, NO2, and etc.
④Strong static electricity or electromagnetic waves
⑤Heat-producing components or inflammable materials are close.
⑥A resistor is sealed or coated with materials such as synthetic resin, and etc.
⑦Water or water-soluble detergent is used for cleaning free soldering or flux coating after
⑧Condensation phenomenon occurs on the object.
⑨Out of the range from -55 °C to +155(125) °C
3. The products have no radiation resistance.
4. It is a must to notify the person in charge of sales of issues on product safety at any time.
In addition, a regular monitor for product safety should be conducted by customers.
□Precautions regarding the use of products.
1. Product characteristics must be evaluated on a board mounted.
2. When transitory load is used in which short-time load is applied such as pulse, a resistor should
be tested on a board mounted. If load is higher than rated voltage under the load conditions at
continuous steps, it causes damages on characteristics or reliability of the resistor. Therefore,
when load exceed the rated voltage, it is not allowed to apply.
3. It is not recommended to use halogen products such as chlorine (Cl), bromine (Br), etc. or
fluxes that are highly active due to the residue that is able to affect the characteristics or
reliability of a resistor.
4. Be careful with the soldering condition to avoid the Ag-solder penetration problems.
