(4) Cautions
• Fluxes
Avoid removing the residual flux with freon-based and ch lorine-based cleaning solvent.
2. Cautions regarding noise
Be aware that when voltage is applied suddenly between the photocoupler’s input and output or between
collector-emitters at startup, the output transistor may enter the on state, even if the voltage is within the absolute
maximum ratings.
USAGE CAUTIONS
<R>
1. Protect against static electricity when handling.
2. Avoid storage at a high temperature and high humidity.
