Fixed capacitor quality inspection, maintenance and repair

In Electronic Infomation Category: F | on February 02,2012

1. Simple capacitor detection method only table in the absence of special conditions, a fixed capacitor is good or bad, and MAX3232CDBR datasheet and the quality level of the resistance with a multimeter files can be judged. Capacity (ltiF more) of the fixed capacitor can be used multimeter ohm (R 1000 files) measured across the capacitor, hands should be a small resistance value side of the swing, then slowly swing back...
