There are CBB words on many capacitors, such as CBB22, CBB81, CBB13, etc., but do you know what? What does a cbb on a capacitor mean? Today, let's explain the specific meaning of CBB in detail.
What does a CBB on a capacitor mean?
CBB capacitors are also known as polypropylene capacitors, which are wound by a metallized polypropylene film.
Polypropylene film is the most core raw material for making CBB capacitors. The metallized film is the evaporation of aluminum or zinc aluminum to the surface of the film under vacuum. The material has high dielectric constant, high insulation resistance, good heat resistance and good tensile resistance, and is suitable for making metallized polypropylene film capacitors.
CBB capacitor features:
cbb capacitor has small loss, strong moisture resistance, excellent electrical performance, good reliability, large capacity, long service life of cbb capacitor and good self-healing performance. Mainly used in higher requirements of the circuit
CBB capacitor is a kind of metallized polypropylene film capacitor, usually followed by two numeric symbols, such as cbb21\/cbb22,1 and 2 are cbb film capacitor serial number code rules: (0: axial lead;
1: radial extraction;
2: DC voltage;
6: AC voltage;
8: DC high voltage). The capacity of the CBB capacitor is expressed as \"nF\
