Electrolytic capacitor

Inside the electrolytic capacitor is an electrolyte material that stores electric charge. It has positive and negative polarity, similar to a battery, and cannot be reversed. The positive electrode is a metal substrate with an oxide film. The negative electrode is connected to the electrolyte (solid and non-solid) through the metal electrode plate.

Description

Type:Polypropylene Film Capacitor
Operating Temperature:-25~+50C
Color:Metal Grey
Shape:Round
Rated Voltage:220v~690V
Application:Power

Definition

Inside the electrolytic capacitor is an electrolyte material that stores electric charge. It has positive and negative polarity, similar to a battery, and cannot be reversed. The positive electrode is a metal substrate with an oxide film. The negative electrode is connected to the electrolyte (solid and non-solid) through the metal electrode plate.

Features

1. Small volume and light weight: It is only 1/4 and 1/5 of the weight and volume of the outdated products respectively.

2. Low loss: With the actual loss less than 0.1%, the capacitor, itself, has low consumption of energy, little radiation, low temperature rise, long service life, and good energy, conservation feecet.

3. Excellent self -healing performance: When a part of the inolation is fed through due to the over voltage, it is capable of self-heaing so as to continue the normal operation, therefore there liability is in proved greatly.

4. Safety: Equipped with self-discharging resistant and safety devices inside, it is safe and reliable.

5. Without oil leakage: In order to avoid oil leakage during operation so as to protect the environment, it employs the microrystlline wax as the Impregnant , which remains solid atordinary temperature and has a drip melting point higher than 70°C.

Application

1. DC blocking: the role is to prevent DC from passing and let AC pass.

2. Bypass (decoupling): Provides a low-impedance path for some paralleled components in an AC circuit.

3. Coupling: as a connection between two circuits, allowing AC signals to pass through and be transmitted to the next level circuit

4. Filtering: This is very important for DIY. The capacitors on the graphics card basically have this function.

5. Temperature compensation: To compensate for the influence of other components’ inadequate temperature adaptability, compensation is performed to improve the stability of the circuit.

6. Timing: The capacitor and resistor are used together to determine the time constant of the circuit. The time constant t = RC.

7. Tuning: System tuning of frequency-related circuits, such as mobile phones, radios, and televisions.

8. Rectification: The semi-closed conductor switching element is turned on or off at a predetermined time.

9. Energy storage: stores electrical energy for release when necessary. Such as camera flash, heating equipment and so on.
