Capacitors

Some articles on capacitors, capacitor:

Motor Capacitor - Run Capacitors
... Run capacitors are mostly polypropylene film capacitors and are designed for continuous duty, and they are energized the entire time the motor is running ... Run capacitors are rated in a range of 1.5–100 microfarads (µF or mfd), with voltage classifications of 370 V or 440 V ... Single phase electric motors need a capacitor to energize a second-phase winding ...
Applications Of Capacitors - Hazards and Safety
... Capacitors may retain a charge long after power is removed from a circuit this charge can cause dangerous or even potentially fatal shocks or damage connected equipment ... camera flash unit powered by a 1.5 volt AA battery contains a capacitor which may be charged to over 300 volts ... usually include instructions to discharge large or high-voltage capacitors ...
Types Of Capacitor
... This article is about the commercial discrete capacitors as customary components for use in electronic equipment ... For the physical phenomenon, see Capacitor ... Capacitors, together with resistors, inductors and memristors, belong to the group of "passive components" for electronic equipment ...
Silver Mica Capacitor - Types - Silvered Mica Capacitors
... Commonly known as silver mica capacitors, these rendered clamped mica capacitors obsolete ... mechanism is needed Silvered mica capacitors are one of the less popularly used types due to their high cost ... They are sometimes informally referred to as mica capacitors ...
Motor Capacitor - Start Capacitors
... Start capacitors above 20 microfarads (µF) are always non-polarized Aluminum Electrolyic Capacitors with non solid electrolyte and therefore they are ... Start capacitors briefly increase motor starting torque and allow a motor to be cycled on and off rapidly ... Start capacitors have ratings above 70 microfarads (µF), with four major voltage classifications 125 V, 165V, 250 V, and 330 V ...
