Introduce the common points and applications of several types of film capacitors: now mass-produced plastic film capacitors include polystyrene, polyethylene, polypropylene, polytetrafluoroethylene, polyester, polycarbonate, and composite films.

 

1) CBB22 metallized polypropylene film DC capacitor. The metallized polypropylene film is used as the medium and the electrode, and is used for the flame-retardant insulating material to encapsulate the unidirectional lead. It has excellent electrical properties, good reliability, low loss and good self-healing performance. Uses: The products are widely used in instruments, meters, televisions, radios and household appliances circuits for DC pulsation, pulse and AC compression, especially suitable for various types of energy-saving lamps and electronic rectifiers. The characteristics and uses of CBB91 metallized polypropylene capacitors are: insulation tape wrapped, epoxy resin potting, and axial lead. It has the characteristics of high insulation, low loss, good frequency characteristics, and low equivalent series resistance. It is suitable for audio frequency dividers, power amplifiers, and post-compensation circuits. It can also be used for DC and AC and pulse circuits of electronic equipment.

 

2) CL21/CBB21 metallized film capacitors, metallized polyester/polypropylene film as the dielectric/electrode is used in a non-inductive winding method, and is encapsulated by epoxy resin. It has excellent electrical properties, good reliability, high temperature resistance, Wide capacity range, good self-healing, small size and long life. Applications are mainly used for DC and VHF signal isolation such as televisions, computer monitors, energy-saving lamps, ballasts, communication equipment, computer network equipment, electronic toys, etc. DC, bypass and coupling/high frequency, AC, pulse, and coupling circuits play a role in filtering, frequency modulation, DC blocking and time control.

 

3) CL20/CBB20 axial metallized film capacitor non-inductive structure, with excellent electrical performance, good reliability, high temperature resistance, small size, large capacity, small high-frequency loss, strong overcurrent capability, suitable for large current and insulation High resistance, good self-healing, long life, stable temperature characteristics, widely used in AC and DC circuits of instruments, meters and household appliances, AC and large pulse circuits such as frequency conversion and frequency division, especially audio frequency divider circuits with high fidelity requirements .

 

4) CL20 metallized polyester film flat axial capacitor. Features: Metallized polyester film is used as medium and electrode, and flame retardant tape is used for outsourcing and epoxy resin sealing. It has excellent electrical properties, good reliability, high temperature resistance, small size, large capacity and good self-healing performance. Purpose: This product is suitable for AC and DC circuits of instruments, meters and household appliances. It is widely used in the frequency dividing circuit of audio system.

 

5) CL19 metallized polyester film circular axial capacitor. Features: Metallized polyester film is used as the medium and electrode, and the flame retardant tape is used for outsourcing and epoxy resin sealing. It has excellent electrical properties, good reliability, high temperature resistance, small size, large capacity and good self-healing performance. Purpose: This product is suitable for AC and DC circuits of instruments, meters and household appliances. It is widely used in the frequency dividing circuit of audio system.

 

6) CBBX2 metallized polypropylene film anti-interference capacitor. Using metallized zinc-aluminum polypropylene film as the medium and electrode, with high-temperature flame-retardant plastic shell, epoxy resin encapsulation, unidirectional lead structure, this product has high resistance to external electrical interference, high reliability, low loss and good It has self-healing characteristics and has better safety protection. Widely used in color TVs, power tools, wireless connectors, cross-power lines, electromagnetic interference filters, power switches and high-power electronic rectifiers.
