!Note
• Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc.
• This catalog has only typical specifications because there is no space for detailed specifications. Therefore, please approve our product specifications or transact the approval sheet for product specifications before ordering.
■ Notice (Soldering and Mounting)
■ Notice (Handling)
1. The component may be damaged if mechanical stress
over this specification is applied.
2. Resistors should not be connected in series to the power
supply as this will produce irregular oscillation. When
resistor is necessary to control sound volume, use
capacitor (1µF) parallel with the buzzer together.
3. Please pay enough attention not to pull lead wire too
much because wire may be broken 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. Washing of the component is not acceptable.
Because it is not sealed.
3. Please do not cover the hole with tape or other
obstacle as this will produce irregular
oscillation.
4. There should not be any obstacle within 15mm from
top of the component as this will produce
irregular oscillation.
