A capacitor is a device that stores energy. Capacitors store energy in the form of an electric field. At its most simple, a capacitor can be little more than a pair of metal plates separated by air. As this constitutes an open circuit, DC current will not flow through a capacitor. If this simple device is connected to a DC voltage source, as

Capacitor failure analysis brings up specific issues that demand corresponding solutions. The ultimate goal of capacitor failure analysis is to determine the fundamental cause of failure or whether the incorrect operation is due to manufacturing flaws, end-user abuse, or other causes. The first step in capacitor failure analysis is finding where an analyst should start looking for a

X and Y capacitors not only keep radio frequency noise generated by the device local to that device, but also protect the device from mains noise and high voltage surges.
Vishay’s line of X1 / Y2 and X2 surface-mount safety capacitors offers devices for operating voltages up to 250 VAC. As surface-mount devices, the capacitors simplify circuit board assembly. The components are supplied in tape and reel packages and are picked and placed the same as all other surface-mount components.
RP serves as a valuable tool for evaluating the safety of MFCs with an unknown SH history, contributing to the assessment of their reliability. Metallized film capacitors (MFCs) are known for their self-healing (SH) properties, enabling efficient and reliable operation, even under challenging conditions.
If one of the capacitors (highlighted in blue) fails shorted, possible effects include: A. a nominal effect that may go unnoticed B. the backplate power supply becoming 0 V, C.

Of note is a 1 nF capacitance value offered in the C0G (NP0) material, which offers a consistent capacitance with respect to both temperature and applied voltage. Surface-mount safety capacitors are available in commercial and Vishay Automotive Grades (AEC-Q200 qualified), with PPAP data upon request.
However, not all types of SH damage lead to catastrophic failure of the capacitor. Thus, finding the threshold of SH that has little impact on the reliability of the capacitor is important.
