Capacitance of a capacitor is defined as the ability of a capacitor to store the maximum electrical charge (Q) in its body. C = Q/V = ε A/d = ε0 εr A/d The ability of a capacitor to store maximum ...

SAN JOSE, Calif.--(BUSINESS WIRE)--Power Integrations (Nasdaq: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today announced CAPZero™-3, the latest ...

Capacitors are able to charge and discharge more quickly than batteries, and can do so hundreds of thousands of times. Batteries, on the other hand, are able to store more energy than capacitors.

EPCOS has optimized its discharge resistor modules based on hybrid ceramics to simplify mounting of discharge resistors on PFC capacitors and enhance reliability. The new module is no longer supplied ...

KEMET has enhanced its high temperature and high voltage capabilities by adding Pulse Discharge Multilayer Ceramic Capacitors. This 200-degree Celsius series delivers reliable short-duration pulse ...

Power Integrations is aiming at larger home appliances needing to meet IEC60335 with an X-capacitor discharger that can empty 6µF in under a second. X-capacitors are part of the EMC input filter of ...

The residual voltage of a capacitor, rated not over 600V, shall be reduced to 50V or less within _____ after the capacitor is disconnected from the source of supply. Article 460 covers the ...

Hybrid "power capacitors" that can store as much energy as lithium batteries, but with much higher charge/discharge rates, a huge range of safe operating temperatures, super-long lifespans and no risk ...

A magnetic resonance imaging method for peering inside capacitors while they are charging and discharging is allowing researchers to scrutinize the ion dynamics that govern the operation and ...

A research group has successfully developed a high-capacity capacitor, an energy storage device -- using a solid electrolyte with high deformability -- that can operate at high temperatures. With this ...
