c Notice (Soldering and Mounting)

1. The component may be damaged if mechanical stress

exceeding specifications is applied.

2. Take care to protect the 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 strictly 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

Ω to 2kΩ. Instead of this measure, a diode may also be

applied as shown in Fig. B.

5. Avoid excessive pulling of the lead wire because the wire

may break or the soldering point come off.

1. Notice (Soldering and Mounting)

(1) Soldering Iron

(a) Immerse lead terminals up to 1.5mm from

component's body in soldering bath of +260±5°C

for 10±1.0 seconds, and then leave components

in natural conditions for 4 hours.

(b) Directly contact the lead terminal with the

tip of the soldering iron for +350±5 °C for

3.0±0.5 seconds, and then leave components

in natural conditions for 4 hours.

(2) Reflow

The component cannot withstand reflow soldering.

2. Please do not insert the component on double-sided

PCB with plated through hole. When melted solder

touches the base of lead terminal, a part of the plastic

case may melt, causing electrical failure.

3. Washing of the component is not acceptable.

Because it is not sealed.
