CBB capacitor detection method (1)

The composition principle of the CBB capacitor is actually relatively simple, that is, two parallel strip plates, the middle insulating medium constitutes a core, and each of the two plates has one lead, that is, two electrodes. The CBB capacitor is a polypropylene capacitor, and its main features are similar to those of polystyrene but small in size and slightly inferior in stability.

CBB capacitors are non-polar, small in size, large in capacity, relatively stable in stability, high in reliability and self-healing. The insulation resistance is high, the frequency characteristics are excellent, and the dielectric loss is small. It can resist high voltage and high current impact, has small loss, excellent electrical performance, high insulation resistance, but large temperature coefficient.

CBB capacitors are used in large numbers in resonant circuits, bypass circuits, and high-frequency, high-voltage circuits. It can be used for DC pulsation and AC voltage reduction in instruments, instruments, TV sets and household appliances. It is especially suitable for various types of electronic rectifiers and energy-saving lamps. It can also absorb high-voltage potential of various contactor contacts. line. The principle is non-polar, the insulation resistance is high, and the frequency characteristics are excellent (the frequency response is wide).
