A capacitor is a passive device on a circuit board that stores electrical energy in an electric field by virtue of accumulating electric charges on two close surfaces insulated from each other. This is a list of known capacitor manufacturers, their headquarters country of origin, and year founded. The oldest capacitor companies were founded ...
A 440-volt capacitor can be used in place of a 370-volt, but not a 370-volt in place of a 440-volt. [2] The capacitance must remain within 5% of its original value. [ 2 ] Round cylinder-shaped dual run capacitors are commonly used for air conditioning , to help in the starting of the compressor and the condenser fan motor. [ 2 ]
By changing the value of the example in the diagram by a capacitor with a value of 330 nF, a current of approximately 20 mA can be provided, as the reactance of the 330 nF capacitor at 50 Hz calculates to = and applying Ohm's law, that limits the current to . This way up to 48 white LEDs in series can be powered (for example, 3.1 V/20 mA/20000 ...
Capacitors for AC applications are primarily film capacitors, metallized paper capacitors, ceramic capacitors and bipolar electrolytic capacitors. The rated AC load for an AC capacitor is the maximum sinusoidal effective AC current (rms) which may be applied continuously to a capacitor within the specified temperature range.

The temperature dependence of the capacitance of PPS film capacitors over the entire temperature range is very small (± 1.5%) compared with other film capacitors. Also the frequency dependence in the range from 100 Hz to 100 kHz of the capacitance of the PPS film capacitors is ± 0.5%, very low compared with other film capacitors.
