CBB capacitor with metallized polypropylene film series structure type, can resist high voltage, large current shock, with a low loss, excellent electrical performance, high reliability and self-healing performance.

Use of CBB capacitors: Awidely used in instruments, instruments, television sets and household electrical circuits, can be used for DC pulsation, especially for various types of electronic rectifier and energy-saving lamp circuit. Also can all kinds of contactor contact high voltage potential absorption line. The principle has no polarity, the insulation impedance is very high, the frequency characteristic is excellent (the frequency response is broad, and the medium loss is very small.

Based on the above advantages, CBB capacitors are widely used in analog circuits. Especially in the intersecting part of the signal, it is necessary to use capacitors with good frequency characteristics and very low dielectric loss in order to ensure that there is not too much distortion when the signal is transmitted. The dielectric constant is high, the volume is small, the capacity is large, the stability is excellent, and it is suitable to make the bypass capacitor. Polypropylene film has low dielectric loss and high insulation resistance, but high temperature coefficient can be used in high frequency circuit.


Characteristics of CBB capacitors:

1. No polarity, high insulation impedance, excellent frequency characteristic and low dielectric loss.

2.The dielectric constant is high, the volume is small, the capacity is larger, and the stability is good.

3.The dielectric loss is insignificant, the insulation resistance is high, but the temperature coefficient is large.
