Input

■ 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

1kΩ to 2kΩ. 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.
