The capacitor can store the charge and has the function of isolating the DC.When the two electrodes of the capacitor are related to the positive and negative electrodes of the DC power respectively, the positive and negative charges will gather on the two electrode plates of the capacitor and form a

A capacitor is an energy storage element that consists of two metal plates and a dielectric interlayer dielectric. Any two conductors that are close together and insulated from each other will make up a capacitor that begins to store charge when a voltage is applied to the conductor.The process of c

Capacitors should be properly protected, such as balanced or differential relay protection or the use of instantaneous overcurrent relay protection, motor capacitance, for 3.15kV and above capacitors, each capacitor must be equipped with a separate fuse, fuse The rated current of the fuse should be

product description:The capacitor uses thickening of the edge of the metal zinc aluminum film as the electrode and medium. The film is wound by a winder and loaded into an aluminum housing. Then fill the housing with high purityCastor oil keeps it in a vacuum and can make the product resistant to hi

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
