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

Because the dielectric inside the capacitor is dissociated under the action of the high voltage electric field, the medium will decompose and precipitate gas, or because of the breakdown of some components, the discharge of the capacitor pole to the shell will cause the medium to precipitate the gas

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.

The lead structure electrolytic capacitance also adopts the "negative pole mark", that is, the casing "-" mark the lead corresponding to the negative electrode. There is also by the length of the lead in identifying, the long lead for the positive pole, the short lead for the negative pole.

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

The bolted aluminum electrolytic capacitor has a clear positive and negative grade mark on the casing. The positive pole is represented by "+" and the negative electrode "-". Most bolted capacitors are engraved with "+" and "-" signs next to the terminals on the cover plate.

Input and output transformer：The main functions of the input and output transformer are to realize impedance matching, to transmit signal voltage and power without distortion, and to isolate DC.

Switching power transformer is an important device in color TV switching power supply. It is a kind of pulse transformer. Its function is to carry on the power transmission, to provide the needed power supply voltage for the whole color TV set and to realize the reliable electrical isolation between

Power transformerIn daily life, all kinds of household appliances use different voltages. It is necessary to use low-voltage DC power supply to work in household electrical appliances. The 220V AC power is converted to low-voltage AC power by power transformer, and then rectified by diode and filter

Intermediate frequency transformerIf the transformer is mainly used in radio frequency selection and interstage coupling. Frequency selection refers to the selection of useful signal frequencies among many signals and the transmission of functional signals. In AM radios, 465kHz useful signals are se
