Thanks for the responses and the link and sorry for the delay in mine and adequate information. The capacitors we are working with are anywhere from 0402 to 0805 package size, various values but our most common seem to be 1000 pF and 3300 pF. Most are soldered with a pick and place machine but some are hand soldered.
Poor power quality can cause innumerable problems in industrial facilities. While a facility owner''s first inclination might be to blame their electric utility for such problems, it''s much more likely that their own equipment is it fault. Up to 80% of power-quality disturbances originate within facilities, rather than from utility-supplied electricity.
The implications include: as a rule, product and process developments follow the rules of APQP1), quality tools such as FMEA2), DoE3) and SPC4) to minimize risks and ensure continuous im …
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other.

When a capacitor is connected with the wrong polarity, common signs include bulging or leakage. You may also notice unusual circuit behavior, such as excessive current draw. In severe cases, the capacitor may overheat and even explode. This is caused by the destruction of the capacitor''s dielectric layer, which leads to internal short-circuiting.
