Passive Plus Inc. (PPI) has added an industry leading 100% automated CSAM (C Mode Scanning Acoustic Microscopy) internal inspection to all of its high power 2225, 3838, 6040 and 7676 capacitor series RF capacitors. The primary benefit of 100% CSAM internal inspection is increased reliability, by screening out electrically undetectable internal defects such as voids, cracks, de-laminations or electrode dis-continuities.
