(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 betw een 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 cu rrent, the characteristics curves may differ from the standard curves due to ctr value variations or the lik e. this tendency may sometimes be obvious, especially below i f = 1 ma. therefore, check the characteristics un der the actual operating conditions and thoroughly take variations or the like into consideration before use. usage cautions 1. protect against static el ectricity when handling. 2. avoid storage at a high temperature and high humidity. data sheet pn10221ej06v0ds 10 ps2501a-1,ps2501al-1
