Generally, two aluminum foils are used as the electrodes, and the middle is formed by overlapping and winding the capacitor paper with a thickness of 0.008 to 0.012 mm.Manufacturing process is simple, cheap, can get a larger capacityUsually in the low-frequency circuit, usually can not be used in hi

In terms of structure, it can be divided into foil type and silver type. The silver electrode is directly on the mica with vacuum evaporation method or sintered by silver coating, due to eliminating the air gap, the temperature coefficient decreased significantly, the stability of the capacitor is a

Capacitance can be adjusted within a small range, and can be fixed to a certain capacitance value after adjustment.Ceramic trimmer capacitor Q value is high, the volume is small, usually can be divided into two kinds of round tube and wafer.Mica and polystyrene media are usually spring-type East, th

Using a high dielectric constant capacitor ceramic extruded into a tube, disk or disk as a medium, and sintered by infiltration of silver plating on the ceramic as an electrode. It is divided into high-frequency porcelain and low-frequency porcelain two.Capacitors with a s

Use sintered tantalum as anode and electrolyte as solid manganese dioxide.Temperature characteristics, frequency characteristics and reliability are superior to ordinary electrolytic capacitors, especially the leakage current is very small, good storage, long life, small capacity error, and small si

Through-core or pillar-type ceramic capacitors, one of its electrodes is the mounting screw. Lead inductance is very small,Good frequency characteristics, low dielectric loss, temperature compensation.Can not be made into a large capacity, will be caused by vibration capacity changes.Particularly su

By a concentration of a special mixture suitable for spraying sprayed into a thin film from the medium and then silver layer electrode sintered into a "monolithic" structurePerformance comparable with mica capacitors, can withstand a variety of climate, usually at 200 ℃ or higher temperature, rated

A thin oxide film is used as a dielectric capacitor and is sandwiched between two pieces of aluminum foil sandwiched between sheets of water-absorbent paper impregnated with a paste electrolyte. Since the oxide film has a unidirectional conductive property, the electrolytic capacitor has polarity.La

The structure is similar to that of paper capacitors, but using low loss plastic such as polyester and polystyrene as the medium. Good frequency characteristics, low dielectric loss. Can not be made of large capacity, poor heat resistance. Filter, integral, oscillation, timing circuit.

Film capacitors are mainly used in many industries such as electronics, home appliances, telecommunications, electric power, electrified railway, hybrid vehicles, wind power generation and solar power generation. The steady development of these industries has promoted the growth of the market of
