Product Introduction
Electrolytic capacitor is a type of capacitor, with a metal foil as the positive electrode (aluminum or tantalum) and an oxide film closely attached to the positive electrode as the dielectric. The cathode is composed of conductive materials, electrolyte (which can be liquid or solid), and other materials. As the electrolyte is the main part of the cathode, electrolytic capacitor is named after it.
Medium material: aluminum electrolysis
Product appearance: cylindrical
Frequency characteristics: high frequency
Lead type: co directional lead wire
Permissible deviation: ± 20%
Installation method: Direct insertion
Temperature range: -40~+105
Pin Description
Generally, there is a white edge on the capacitor, and the first pin facing it is the negative pole. If there is no white edge, it is considered that the long lead is the positive pole! The short lead is negative!
Product features:
1. Small size and large capacity
2. Ripple current resistance: small loss tangent, small leakage current, low internal resistance, low ripple
The function of electrolytic capacitors:
Make the starting winding of the motor run ahead of the starting current by one phase angle during startup, thereby obtaining the starting torque and making the motor easy to start.
The functions of electrolytic capacitors in switching power supplies include:
1. DC blocking: Its function is to prevent DC from passing through and allow AC to pass through.
2. Bypass (decoupling): Provides a low impedance path for certain parallel components in an AC circuit.
3. Coupling: As a connection between two circuits, it allows AC signals to pass through and be transmitted to the next level circuit.
4. Filtering: Transforming the rectified sawtooth wave into a smooth pulsating wave, close to DC
5. Energy storage: storing electrical energy for release when necessary.
Application instance
Electrolytic capacitors are widely used in household appliances and various electronic products, such as DVB power boards, security power supplies, power adapters, switching power supplies, etc.
