CBB capacitance detection method(I)

The principle of the composition of the CBB capacitor is actually relatively simple, that is, two parallel dotted plates, the middle insulating medium composes a core, and two plates each have one lead-out, ie, two electrodes. The CBB capacitor is a polypropylene capacitor. Its main feature is similar to that of polyphenylene, but its volume is small and the stability is slightly poor.

CBB capacitor is non-polar, small size, large capacity, good stability, high reliability and strong self-healing. Insulation resistance is high, frequency characteristics are excellent, and dielectric loss is small. High voltage, high current impact, low loss, excellent electrical performance, high insulation resistance, but large temperature coefficient.

CBB capacitors are widely used in resonant circuits, bypass circuits, and high-frequency high-voltage circuits. For instruments, meters, televisions and household appliances, DC pulse and AC voltage drop can be used. It is especially suitable for various types of electronic rectifiers and energy-saving lamp circuits. It can also absorb the high-voltage potential of various contactor contacts. line. The principle is non-polar, high insulation resistance, excellent frequency characteristics (wide frequency response).
