Product Information Film Capacitor Technical Notes Hybrid

Film capacitors rated voltage derating by category temperature use of the capacitors at high temperature shortens the capacitor life due to thermal deterioration.

Film capacitor frequency. 3 55 25 0 25 50 75 100. The capacitance frequency dependence of polyester film capacitors compared with the other film capacitors is 3 in the range from 100 hz to 100 khz at the upper limit. When operating capacitors at high temperature please derate the operating voltage in conformance with the graphs below.

Fig12 rated voltage derating by high frequency. Electrocube offers a line of high temperature film capacitors that exhibit superior electrical characteristics over an extremely wide temperature range. Film capacitors are widely used for dc fltering in power supplies.

The capacitance tolerance indicates the acceptable deviation from the rated capacitance at 20 0c. It is inversely proportional to frequency and capacitance. They offer tight capacitance shift versus temperature and frequency lightweight no oil or electrolyte and flexible packaging options.

They will energize high frequency switching power supplies motor speed controls power conditioning products and other high performance power applications. 5 vac and a temperature of 20 0c. C n is the capacitance for which the capacitor is designed.

Dry plastic dielectric film capacitors offer high reliability and low loss characteristics desirable in power electronic applications. Dry film capacitors for high frequency power electronics. They offer a very low temperature variation over the temperature range typically 15.

Ic power film capacitors are designed to carry the weight of demanding conditionshigh ripple current pulse current voltage up to 10kvdc and greater than 100000 hours. C the reactance is the capacitors opposition to passing ac current. Among the selection of capacitors are ecr series which are ideal for medical devices computers and precision testing.

Whether for high current or high frequency applications these film capacitors are preferred for their utility in demanding environments and proprietary design and manufacturing processes. Also the temperature and frequency dependence of the dissipation factor are higher for polyester film capacitors compared with the other film capacitor types. Frequency discriminating film capacitors are a series of products that has been developed to enable switching power supplies with optimum characteristics.

Temperature oc capacitive reactance x. Their function is to smooth out the dc voltage waveform after rectifcation. These film capacitors are only manufactured as the metallised film types.

Its value is typically measured at a frequency of 1 khz 20 at voltage of 003 x urdc max. 1 x c.
