Thin film capacitor, they are widely used because of its particularly high insulation resistance, wide frequency response and a nonpolar, so the film capacitor is often used in integrated circuit board, analog circuit, and so on. Especially in the aspect of signal coupling performance of the play is very superior, compared with other media, film capacitor dielectric loss of small, wide frequency response, can guarantee the time signal in the transmission will not change. The application of film capacitor in the application of power electronic circuits. Film capacitor is used in it, a buffer is mainly plays an electric current and clamp, resonant bypass and inhibitory effect of power supply of electromagnetic interference and so on. When film capacitor is used as a by-pass, it is mainly up to reduce the impedance of the dc bus and absorb the ripple current from the load, thereby effectively restrain dc bus voltage fluctuations in due to the load mutation. When the device is used for the resonant converter, it can rise to realize the function of the resonant with inductance. Film capacitor of the points for attention during the application of the first is to pay attention to carefully observe the working voltage of the state, when the job is very unstable voltage, first don't use film capacitor. When voltage change speed, the speed is relatively stable can be used. To meet the flow through the effective value of capacitor current and peak current. Thin film capacitor application example 1: CL21 / CBB21 metallized film capacitor ( CL21- B / CBB21 - Metal bellows) B , the use of metallized polyester/polypropylene film as the dielectric/electrode with non-inductive winding way, epoxy resin coating, have excellent; Good reliability; High temperature resistant; Wide range of capacity; Small volume; Good self-healing; Long life characteristics, mainly used in television; Computer monitor; Energy-saving lamps. Ballast. Communications equipment; Computer network equipment; Electronic toys, such as every other dc dc and signals to VHF range. widely used; The bypass and the coupling/high frequency; Exchange; Pulse; Filter in the coupling circuit; FM. Every other dc and time control. 2: CBB221 metallized polypropylene film capacitor, metallized polypropylene film as the dielectric and electrode, with resistance to burn insulation coating unidirectional lead, have excellent; Good reliability; Low dissipation and good self-healing properties. Wide range of USES, use of instrument; The instrument; Television; Makes the dc pulsed radio and household electrical appliances circuit; Pulse pressure and communication will be used, especially suitable for various types of energy-saving lamps and electronic rectifier. 3: CL20 metallized polyester film flat axial capacitor ( Metallized terylen capacitance) , with metallized polyester film as the dielectric and electrode, outsourcing and epoxy resin honey, with flame retardant tape with excellent; Good reliability; High temperature resistant; Small volume; Large capacity and good self-healing properties. This product is suitable for the instruments; Instruments and appliances ac/dc circuit, widely used in audio frequency division circuit. 4: CL20 / CBB20 axial metallized film capacitor induction type structure, with excellent; Good reliability; High temperature resistant; Small volume; Large capacity, small loss at high frequency; Over current capability is strong, suitable for large current; High insulation resistance. Good self-healing, long life; Stable temperature characteristics, are widely used in instruments; Instruments and appliances ac/dc circuit; Variable frequency, frequency division and other exchanges, big pulse circuit, especially the high fidelity audio frequency divider circuit. 5: CL19 metallized polyester film circle axial capacitor with metallized polyester film as the dielectric and electrode, outsourcing and epoxy resin with flame retardant tape seal, have excellent; Good reliability; High temperature resistant; Small volume; Large capacity and good self-healing performance, the product is suitable for the instruments; Instruments and appliances ac/dc circuit, widely used in audio frequency division circuit. Polystyrene film capacitor, small dielectric loss, high insulation resistance, but the temperature coefficient is big, can be used in high frequency circuit.
