Please read CAUTION and Notice in this catalog for safety. This catalog has only typical specifications. Therefore you are requested
to approve our product specification or to transact the approval sheet for product specification, before your ordering.
Washing of the component is not acceptable,
because it is not sealed.
1. The component may be damaged if mechanical stress
2. Please pay attention to protect operating circuit from
3. If DC voltage is applied to the component, silver migration
4. The resistor should be used as shown in Fig. A.
5. Please pay enough attention not to pull lead wire too
