(a) soldering of leads should be made at the point 1.5 to 2.0 mm from the root of the lead. (b) please be sure that the temperature of the package would not be hea ted over 100 ? c.
data sheet pn10244ej02v0ds 11 ps2706 - 1 (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 photocouplers input and output or between collecto r - 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 b efore 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 t he 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 t emperature and high humidity.
