Screening flows available on request. X-Ray shall be performed in lieu of Precap Inspection – Consult factory. 3/ Consult factory for package outlines. 4/ All voltages are measured with an automated test set using a 35 msec test time. Longer or shorter test time will have a corresponding effect on the measured value due to heating effects. / Exponential waveform i.a.w. IEC60-1 10/1000 uS pulse
