Whether ceramic capacitors are connected in series and in parallel is easy to breakdown

We have found many small problems in daily operations, and there are doubts if they are not handled properly. Next, the editor talked about a common problem with ceramic capacitors. Whether ceramic capacitors are connected in series and in parallel is easy to break down. In fact, as long as the ceramic capacitor does not exceed the withstand voltage, it will not break down. Why, look at the reasons below and you will know.

1. Ceramic capacitors have a withstand voltage value.

2. Capacitors should be used withstand voltage regardless of series or parallel connection. The selected capacitor withstand voltage is higher than the large voltage value of the circuit.

3. For example, in a 300V circuit, two capacitors with a withstand voltage of 450V are not broken down in series.

4. If a 300V circuit is connected in parallel with a 100V and a 450V capacitor, the 100V capacitor will break down if the partial voltage exceeds 100V.

5. At this time, it is necessary to look at the capacity of the ceramic capacitor. The smaller the capacitance, the higher the partial pressure and the inverse relationship.

6.2 identical capacitors are connected in series, the total capacity is halved, and the total withstand voltage is doubled.
