dry electrolytic capacitor的意思|示意

'

Dry electrolytic capacitors are widely used in electronic circuits due to their small size, low cost, wide capacitance range, and high working voltage. The uses of dry electrolytic capacitors can be classified as follows:

1. Filtering: Dry electrolytic capacitors are commonly used in power supply circuits for smoothing and filtering currents and voltages. By blocking some of the alternating current components and allowing direct current to pass through, the dry electrolytic capacitor can reduce the ripple current and voltage in the power supply circuit.

2. Coupling: Dry electrolytic capacitors are usually used in the coupling circuit to transmit signals between two sets of circuits while blocking the direct current components. This is mainly used in audio transmission circuits in radio and amplifier circuits.

3. Blocking: Dry electrolytic capacitors are often used in blocking circuits to conduct alternating current while blocking direct current.

4. Oscillation: Dry electrolytic capacitors are usually used in oscillation circuits to produce oscillating signals and thus obtain various waveforms.

5. Bypass: Dry electrolytic capacitors are often used in bypass circuits to provide path to bypassing current and to reduce impedance.

Overall, dry electrolytic capacitors are critical components for many electronic circuit applications, and can be used for a variety of functions, such as filtering, coupling, blocking, oscillation, and bypass.
