What are the reasons for frequent capacitor burnout?
1 Answers
Generally, the reasons for capacitor burnout include the following: 1. Burnout caused by insufficient voltage tolerance and overvoltage; 2. Burnout caused by exceeding the maximum working current; 3. Burnout caused by exceeding the maximum working temperature; 4. Burnout caused by frequency mismatch and excessive loss; 5. Burnout caused by the drying up of the electrolyte. Below is additional information about capacitors: 1. Capacitance is a physical quantity that characterizes the ability of a capacitor to hold an electric charge. The amount of charge required to increase the potential difference between the two plates of a capacitor by 1 volt is called the capacitance of the capacitor. From a physics perspective, a capacitor is a static charge storage medium with a wide range of uses. It is an indispensable electronic component in the fields of electronics and electrical engineering, mainly used in circuits for power filtering, signal filtering, signal coupling, resonance, DC blocking, etc. 2. Common capacitor failures include breakdown, leakage, open circuit, and reduced capacity. High-voltage capacitors with multiple components connected in series internally may also experience faults where partial component breakdown leads to an increase in capacitance.
