Film electric bai capacitor is also called CBB capacitor, it has two kinds of dielectric classification: polypropylene film du and polyester film, zhi polypropylene film features very low high dao frequency loss, high capacity stability, small negative temperature coefficient, very high insulation resistance, very low dielectric absorption coefficient, good self-healing, dielectric strength, such as CBB11, CBB13, CBB21, CBB62, CBB81, etc.
CBB21 is metalized, epoxy resin package, widely used; CBBS is suitable for color TV S correction circuit; CBB13 is metal foil type, suitable for high frequency and pulsating circuit; CBB81 is made of film/foil type series structure, epoxy resin package, CBB81B double metal film foil type series structure, CBB81C is double side metalized series structure, these three are suitable for high voltage, high frequency, high current high frequency and high current applications
Polyester film has wide working temperature range, high dielectric constant, high capacity stability, positive temperature coefficient, high insulation resistance, good self-healing, film thickness up to 0.9μm, and large volume ratio. Such as CL11, CL21, CL12, etc.
Note: When capacitors are used in power lines to eliminate noise, not only normal voltage but also abnormal pulse voltage (such as lightning) will occur, which may cause the capacitor to smoke or catch fire.
Therefore, the safety standards of cross-line capacitors are strictly regulated in different countries
Please use CBB62, MKP type capacitors which are certified for safety
DC capacitors are not recommended to be used as crossover capacitors
At present, film capacitors are generally used in the temperature range of -40℃～+85℃, but with the promotion of capacitor applications, the use requirements are also increasing, and now foreign countries have introduced film capacitors PPS with a temperature resistance of 125℃, which are characterized by a particularly high temperature performance and a very small loss angle tangent, and are suitable for very high frequency and high temperature high current occasions.
