The difference between CL21 capacitor and CBB capacitor

There are many types of capacitors, such as safety capacitors, ceramic capacitors, and film capacitors. So, what is the capacitance of the CL21 capacitor and the CBB capacitor? What is the difference?

The CL capacitor can be called a polyester film capacitor, and the CBB capacitor can be called a polypropylene film capacitor, which has both self-healing and non-inductive properties. The main differences between the two are as follows:

1. At high frequencies, the stability of the CBB capacitor is higher than that of the CL capacitor.

2. Under the same temperature change conditions, the CBB capacitor capacity varies with temperature over the CL capacitor.

3. The loss of the CBB capacitor is smaller than the CL capacitor. Under the condition of 1 kHz, the CBB capacitor loss tangent is less than 0.001, and the CL capacitor has a loss tangent of less than 0.01.

4. Both CBB and CL capacitors are particularly well insulated and superior to others, but CBB capacitors have better insulation than CL capacitors.

5. The CL capacitor is smaller than the CBB capacitor. With the same voltage and the same capacity, the volume of the CL capacitor can be made smaller than the CBB capacitor, which is practical for volumetric installation requirements.

CBB capacitor performance is better, the unit price is expensive, so there are many merchants using CL capacitors to impersonate CBB capacitors on the market, so the recommended method is to identify two kinds of capacitors: measure the loss value, if it is less than 0.001, it is CBB capacitor, otherwise it is CL capacitor. .
