How much do you know about the capacitor?

With the rapid development of electronic information technology, the speed of updating of digital electronic products is increasing. The production and sale of entertainment electronics products such as flat screen TVs (LCD and PDP), notebook computers, digital cameras and other products continues to grow, which has driven the condenser industry forward.

What are the relevant parameters of the capacitor?

1. Coupling: The capacitor used in the coupling circuit is called the coupler capacitor. This type of capacitor switching is often used in resistor capacity coupling amplifiers and other coupling circuits to block DC and AC.

2. Filtering: The capacitor used in the filter switch is called a filter capacitor. This capacitor switching is used in the power supply filtration and in different filter connections. The filter probe removes the signal in a specific frequency band from the total signal.

3. Disconnect: The capacitor used in the disconnect circuit is referred to as the disconnect capacitor. This capacitor switch is used in the DC supply circuit of the multi-stage amplifier. The decoupling capacitor eliminates harmful low frequency cross-connections between the individual amplifiers.

4. High frequency vibration elimination: The capacitor used in the high frequency vibration elimination circuit is called a high frequency vibration elimination capacitor. In the audio feedback amplifier, this capacitor switch is used to eliminate the high-frequency noise that may occur in the amplifier to eliminate the possible high-frequency self-excitation of vibration.

5. Resonance: The capacitor used in the LC oscillating circuit is called a resonance capacitor and this capacitor circuit is required in both the LC parallel and the serial resonance circuit.

What to do if the capacitor triggers?

The capacitor'sprotection switch has been triggered and the shunt fuse has not been interrupted. The capacitor should be discharged for three minutes before checking the power cable of the power switch of the converter and the outside of the capacitor. If no anomaly is detected, this can be caused by the voltage fluctuation of the external error bus. After inspection, it may be tested; otherwise a comprehensive switch of protection should be carried out. If the cause is still not found by the above mentioned inspections and tests, it is necessary to proceed in accordance with the system and to test the capacitors gradually. No sample investment is allowed until the reason is known.

What role do capacitors play?

Capacity refers to the ability to hold an electric field. Each electrostatic field consists of many capacitors. An electrostatic field has a capacity. The capacity is described by an electrostatic field. It is generally assumed that an isolated conductor constitutes an infinite capacity, and the grounding of the conductor is tantamount to being connected to infinity and connected to the Earth as a whole. Capacity (or capacity) is a physical size that expresses the ability of a capacitor to hold charge. Physically speaking, a capacitor is a static storage medium, and the load can be permanently present. This is its property, and it has a wide range of applications. It is an indispensable electronic component in the electronics and energy sector.
