Filmkondensator är en elektronisk komponent som används i många hushållsapparater och har ett brett spektrum av applikationer! Filmkondensatorer har gradvis ersatt elektrolytkondensatorer av aluminium. Filmkondensatorer kan delas in i vilka två kategorier, och vad är dess roll, tillsammans med de små att förstå.
Film capacitors are metal foil as electrodes, and polyethylenes, polypropylene, polystyrene or polycarbonate and other plastic films, from the two ends of the overlap, winding into a cylindrical structure of the capacitor. The working principle of a film capacitor is the same as that of a general capacitor, which is to store electrical energy by storing charge on the electrodes, and is usually used together with an inductor to form an LC oscillation circuit.
Filmkondensatorer kan delas in i DC-filmkondensatorer och AC-filmkondensatorer: DC-filmkondensatorer är filmkondensatorer som arbetar i kretsar som drivs av DC-strömförsörjning, som kan delas in i fyra kategorier: allmän användning, elektromagnetisk störningsdämpning, puls och precision; AC-filmkondensatorer är filmkondensatorer som arbetar i kretsar som drivs av AC-strömförsörjning, som kan delas in i motorstartdrift, effektfaktorkompensation etc.
Film capacitors are widely used in integrated circuit boards, analog circuits and other circuits because of their high insulation impedance, wide frequency response and non-polarity. Especially in signal cross-connection, the performance of film capacitor is very good. Compared with other media, the dielectric loss of film capacitor is small and the frequency response is wide, which can ensure that the signal will not change during transmission. Nowadays, in order to meet people’s requirements for audio quality and improve the sound quality, the film capacitors used in audio equipment are more and more advanced, and the price is not the most important consideration, so PP and PS capacitors are used in audio equipment more and more frequently and in higher quantity.
