Ceramic chip capacitor is a kind of capacitor which is made of ceramic material, coated with a metal film on the ceramic surface and then sintered at high temperature as an electrode. Ceramic chip capacitors are often used as circuit capacitors and pad capacitors in high stability oscillation circui

1. Filtering, in the power supply circuit, the rectifier circuit changes the AC into pulsating DC, and after the rectifier circuit, a large capacity electrolytic capacitor is connected, and the charge-discharge characteristics are utilized. The pulsating DC voltage after rectifying is changed into a

Determination of polarity of Electrolytic CapacitorElectrolytic capacitors with unknown polarity can be measured by the electrical barrier of the multimeter We know that the leakage current of the electrolytic capacitor is small only when the positive electrode of the electrolytic capacitor is posit

Characteristics of capacitors (Alternating current) A capacitor is a container in which charges are stored. It consists of two pieces of metal near to each other, separated by insulating material. According to the insulating material, a variety of capacitors can be made, such as mica, porcelain, pap

Electrolytic capacitors are the most suitable for power frequency filtering or bypass or interstage coupling in low-frequency circuits. And the lower the circuit impedance, the more reliable. When the electrolytic capacitor works, it is equivalent to an electrolytic cell, one of which is the electro

Fully consider ripple voltageGenerally electrolytic capacitors have positive and negative electrodes. When used in pulsating circuits with both DC and AC voltage components, special attention should be paid to its working characteristics. When the electrolytic capacitor is in use, it must meet the v

When working voltage is loweredReducing the working voltage of electrolytic capacitor is the most effective way to prolong the service life and improve the reliability of the capacitor. Because the failure rate of electrolytic capacitor is directly proportional to the ratio of applied voltage to rat

Chip electrolytic capacitance is also known as chip aluminum electrolytic capacitance, the chip aluminum electrolytic capacitor is made of aluminum cylinder as negative electrode, which contains liquid electrolyte, inserted into a curved aluminum strip to make positive electrode, and also needs to b

Chip aluminum electrolytic capacitance is also called chip aluminum electrolytic capacitance. Chip aluminum electrolytic capacitor has no casing, so it has the information of capacity, voltage, positive and negative electrode and so on at the bottom of aluminum shell.

Solder aluminum electrolytic capacitance is also called "horn capacitance". At present, all manufacturers choose "negative electrode mark", that is, "bushing"-"the corresponding pin is the negative electrode." The positive and negative electrodes of electrolytic capacitors are also distinguished on
