■ Notice (Soldering and Mounting)
■ 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.

1. Notice (Soldering and Mounting)
(1) Soldering Iron
(a) Lead terminals are immersed up to 1.5mm from
components body in soldering bath of +260+/-5
degrees C for 10+/-1.0 seconds, and then
components shall be left in natural condition
for 4 hours.
(b) Lead terminal is directly contacted with the
tip of soldering iron of +350+/-0.5 seconds, and
then components shall be left in natural
condition 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 to the base of lead terminal,
a part of plastic case shall be melted and it
may cause electrical failure.
3. Washing of the component is not acceptable.
Because it is not sealed.
