Washing of the component is not acceptable, because
it is not sealed.
1. The component may be damaged if mechanical stress
2. Take care to protect operating circuit from surge voltage
3. If DC voltage is applied to the component, silver migration
4. The resistor should be used as shown in Fig. A.
5. Avoid excessive pulling of lead wire because wire may

resulting from excessive force, falling, shock or
may occur. Please pay full attention to avoid subjecting
the component to DC voltage for long periods.
A suitable resistance value should be chosen, preferably
1k to 2k . Instead of this measure, a diode may also be
applied as shown in Fig. B.
