The company's product series are:
1, ceramic capacitor series:
A: Safe ceramic capacitors, ceramic media with high dielectric coefficient and fire-retardant epoxy package, are suitable for use in power circuit noise suppression circuits of electronic equipment, as well as antenna coupling jumper and bypass circuits.
B: High voltage ceramic capacitor with high DC voltage resistance suitable for high voltage bypass and coupling circuits. The low loss high voltage wafer ceramic dielectric hollow appliance has low dielectric loss, especially suitable for use in the line scanning circuit of TV receiver.
C: Monolithic ceramic capacitor has the characteristics of large capacitance, small volume, high reliability, stable capacitance, high temperature resistance, good insulation, low cost, so it is widely used in the circuit of isolating, oscillating, coupling, filtering, bypass and so on in the electronic whole machine.
D: Laminated laminated ceramic capacitors are mainly used in backlight inverters, buffer circuits of switching power supplies, various high-voltage electronic circuits, information equipment such as modems, AC adapters, chargers and DC converters, etc. It is characterized by epoxy molding package, solid structure, single-layer ceramic chip, high reliability, moisture resistance, good environmental adaptability, suitable for reflow SOLDERING SMT production mode, has a wide rated voltage range.
E: adjustable chip ceramic capacitor. the design is small, can be used for small electronic products, and can adjust capacitance value from multiple angles. Solid design, can avoid the negative effects of vibration, and can still keep the capacitance value unchanged.
2, varistor series: zinc oxide varistor and explosion-proof type varistor, they are widely used in electrical and electronic equipment instantaneous overvoltage protection and surge absorption. It has the characteristics of fast response speed, large current capacity, no polarity, no continuous current, long life, wide voltage range and so on. Can protect communication facilities, telemetry equipment, electronic control devices and other electronic equipment, can also protect the dc low voltage state of the work of integrated circuits and various semiconductor devices;
3, thermistor series: NTC thermistor and PTC thermistor, they are widely used in conversion power supply, switching power supply, UPS power supply, all kinds of electric heaters, electronic ballasts, all kinds of electronic device power circuit protection and all kinds of kineshobe, display, incandescent lamp and other lighting lamp filament protection. Its characteristics are: small size, large power, strong ability to suppress inrush current; Fast reaction speed, high reliability, long life; The material parameter (B value) is large and the residual resistance is small; Wide range of work, complete product series.
