With the rapid development of science and technology, every year endless electronic products appear on the market. Different electronic components are used in the circuits of these electronic products. This article will tell you something about CBB film capacitors.
Film capacitors use polyethylene, polypropylene, polystyrene, polycarbonate and other plastic films as the medium, metal foil, metal vaporized silver layer and metallized film as electrodes, and tinned copper-clad steel wires as pins. After the two ends are overlapped, the capacitor is wound into a cylindrical structure and encapsulated with flame retardant epoxy resin. The CBB capacitors discussed in this article are film capacitors, which are metallized polypropylene film capacitors.
In fact, CBB capacitors are also divided into various types. The common ones are square and axial. As a film capacitor, it has the following advantages:
1. Low loss, no polarity, excellent frequency characteristics;
2. High dielectric constant, small volume and large capacitance;
3. High insulation resistance and good stability;
4. High temperature resistance, can operate normally in the range of -40℃~105℃;
5. Excellent electrical performance and self-healing properties.
Due to the above advantages of CBB capacitors, the performance is similar to that of polystyrene capacitors, but the volume is small, so it can replace most polystyrene or mica capacitors in circuits with higher requirements, and can be used in high-frequency pulse occasions, AC occasions, and high-stability timing occasions , temperature compensation circuit, switching power supply system and color TV industry, lighting LED circuit, filter circuit, etc.
CBB capacitors are widely used, and when purchasing CBB film capacitors it is advisable to choose reliable manufacturers in order to save a lot of troubles.
