Notice (Soldering and Mounting)
Washing of the component is not acceptable, because
it is not sealed.
Notice (Handling)
1. The component may be damaged if mechanical stress
exceeding specifications is applied.
2. Take care to protect operating circuit from surge voltage
resulting from excessive force, falling, shock or
temperature change.
3. If DC voltage is applied to the component, silver migration
may occur. Please pay full attention to avoid subjecting
the component to DC voltage for long periods.
4. The resistor should be used as shown in Fig. A.
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.
5. Avoid excessive pulling of lead wire because wire may
break or soldering point may come off.
