Different characteristics of paper capacitors and film capacitors
1.Paper capacitor
The paper capacitor is made of two tinfoil or aluminum foil as the electrodes, and the middle of the capacitor paper with a thickness of 0.008 to 0.012 mm is separated by overlapping winding.
The utility model has the advantages of simple manufacturing process, low price, and large capacitance. Paper capacitors are generally used in low frequency circuits, which usually cannot be applied at frequencies above 3 to 4 MHz. The voltage withstand value of the oil-immersed capacitor is higher than that of the ordinary paper capacitor, and the stability is good, which is suitable for the high-voltage circuit.
The structure of the film capacitor is similar to that of the paper capacitor. But its use of polyester, polystyrene and other low-loss plastic material as a medium, so the frequency characteristics of good, small dielectric loss can not be made into a large capacity, poor heat resistance filter, integration, oscillation, timing circuit.
