Handling Precautions


Deterioration of solderability can be caused by oxidization/ sulfurization due to the high temperature, high humidity or chlorine/sulfur gas. Parts should be used within 6 months if possible and stored below 40°C and below 70% RH in an atmosphere free of sulfur, chlorine or toxic gasses.

These EMI filters are made of ceramics. Please avoid dropping or other mechanical shock that could damage the parts.

The products kept in your storage for over 6 months should be used only after checking solderability.

Precautions for the safety use

The products are designed and manufactured for the use in ordinary electronic products. There is a possibility to cause performance deterioration or failure depends on the way of using. In case of the product breaking down in short mode, capacitor itself generate heat due to excessive current, and the circuit board may be damaged by a fire. Therefore, please talk to us in the case of these products are used in the applications/products which require high quality and reliability, where product defects or its misconduct might may directly or indirectly threaten human life or hurt human body, may damage properties etc., or may cause a social problem, please consult sales offices well in advance.
