Film Capacitor Ac Rating

- March 30, 2018

Ac rated voltage of table 1 is not applicable to all kinds of capacitors. In case of a plastic film capacitor the operating temperature the temperature measured on the hottest point of the capacitor depends upon the type of dielectric used the ambient temperature in which the capacitor is placed the type of voltage applied ac.

Film capacitor ac rating. But to a first approximation the voltage rating of a film capacitor depends primarily on the thickness of the plastic film. Please view our selection of film capacitors below. Capacitors especially designed for mains.

Capacitor ac dc rating maximum. 1 kv 1000 volts. For other series please consult our sales oces.

I have heard you can operate ac capacitors at 300 of their rating with dc but i am not sure if this is true. Ac voltage the ac voltage ratings refer to clean sinusoidal voltages without transients. A typical start capacitor rating ranges from 25 uf up to 1400 uf and 110 vac to 330 vac.

But even film caps intended in ac applications. Check the voltage rating. This is the maximum voltage the capacitor is designed to handle.

Film capacitors are available at mouser electronics from industry leading manufacturers. Mouser is an authorized distributor for many film capacitor manufacturers including cornell dubilier epcos kemet panasonic vishay wima and more. This applies also to capacitors that are rated with ac voltages 250 vac.

The start capacitor is connected into the motors electrical circuit at rest. For polypropylene film capacitor applications refer to the voltage performance curves. I have some ac capacitors and was curious to how to convert the ac rating to a dc rating.

The capacitors must not therefore be operated in mains applications eg. If there is room on the body of the capacitor the manufacturer usually lists voltage as a number followed by a v vdc vdcw or wv for working voltage. Please inquire us to details.

For example with the minimum available film thickness of polyester film capacitors about 07 mm it is possible to produce capacitors with a rated voltage of 400 vdc. Current ratings can be derived from these curves for sine or near sine applications these curves are based on natural convection at 850c ambient temperature. It gives the motor an initial push on start up briefly increasing its starting torque and allowing the motor to be cycled on and off quickly.
