• 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)
1. Washing of the component is not acceptable, because
it is not sealed.
2. Please do not cover the hole with tape or other
obstacle as this will produce irregular
oscillation.
3. There should not be any obstacle within 15mm from
top of the component as this will produce
irregular oscillation.
■ 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 standard self-driven circuits utilizes
transistor switching. Since the circuit constants
for hfe of the transistor are optimally chosen to
maintain stable oscillation, please design a circuit
following the standard.
