What should be paid attention to in the application of fixed capacitors?

Last Update Time: 2018-12-15 10:55:38

1.The actual voltage ( including the pulse voltage ) added by the two collapses of the capacitor shall not be greater than the rated DC operating voltage.


2.Different characteristics of the capacitor can not be arbitrarily replaced, such as low frequency polyester capacitor can not be used for high-frequency circuit.


3.The error of the fixed capacitor used in the resonant circuit is not too large.


4.Fixed capacitors with small insulation resistance can not be used.


5.When there is no suitable capacitor, it can be used in parallel or in series.


6.Must be connected to the circuit in accordance with the correct polarity, that is, the positive electrode is connected to a high potential, and the negative electrode is connected to a low potential. If the two poles are reversed when used, the capacitor will be broken down and become invalid, and will explode when powered.


7.When the welding action should be fast, do not let the soldering iron high temperature damage the sealing material, causing the electrolyte leakage.

 If the storage time of the electrolytic capacitor is too long, the insulation resistance and the capacitance will be reduced, and the performance will be deteriorated. The life of the electrolytic capacitor is 5 to 10 years.

Electrolytic capacitors may also be naturally damaged if not placed for a long time. Therefore, in the purchase of electrolytic capacitors, should try to choose the recent products.
