The ceramic capacitor is a capacitor made of a ceramic material as a medium, a metal film coated on the surface of the ceramic, and then sintered at a high temperature as an electrode. It is commonly used in high-stability oscillator circuits as loops, bypass capacitors, and pad capacitors. In the process of making ceramic capacitors, we all encounter short-circuit conditions. What causes a short circuit?
A short circuit is that the power supply is directly connected to the closed circuit by the wire without being loaded. The short-circuit current refers to the current when it is not connected, which is equivalent to the current when a direct wire is connected to the positive and negative phases of the battery. The reason for the short circuit of the ceramic capacitor appears as follows:
1) Quality is not enough
2) High voltage breakdown
3) Voltage instability
4) The reserved margin is not enough
5) Ambient temperature is out of range
6) Damage to the ceramic capacitor during transportation
In addition to some of our daily considerations, we must pay attention to quality in the process of procurement, and manufacturers with guaranteed after-sales can avoid unnecessary troubles.
