• Time (each pins) 3 seconds or less

• Flux Rosin flux containing small amount of chlorine (The flux with a

maximum chlorine content of 0.2 Wt% is recommended.)

Data Sheet PN10202EJ04V0DS

PS2841-4A,PS2841-4B

(4) Cautions

• Fluxes

Avoid removing the residual flux with freon-based and chlorine-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.

3. Measurement conditions of current transfer ratios (CTR), which differ according to photocoupler

Check the setting values before use, since the forward current conditions at CTR measurement differ according

to product.

When using products other than at the specified forward current, the characteristics curves may differ from the

standard curves due to CTR value variations or the like. Therefore, check the characteristics under the actual

operating conditions and thoroughly take variations or the like into consideration before use.

USAGE CAUTIONS

1. Protect against static electricity when handling.

2. Avoid storage at a high temperature and high humidity.
