*FAQ:
What is the role of film capacitors in many fields?
1) Application in power electronic circuit. Film capacitors are used here mainly as a buffer and clamp for power and current, resonant bypass, and suppression of electromagnetic interference of the power supply.
2) When the film capacitor is used as a bypass, it mainly reduces the impedance of the DC bus and absorbs the ripple current from the load, thereby effectively suppressing the fluctuation of the DC bus voltage due to sudden changes in the load.
3) When the device is used in a resonant converter, it can function to achieve resonance together with the inductor.
Film capacitors play different roles in different fields. If you have any technical questions, you can consult Dongguan Zhixu Electronics (JEC).
How to distinguish between CBB capacitors and CL capacitors?
1.Identify from the capacitor identification
For larger film capacitors, their material is generally printed on the capacitor. For example, those starting with CBB are metallized polypropylene film capacitors, such as CBB21/CBB22/CBB13/CBB81/CBB20, etc. There is also one that starts with CL They are generally metallized polyester film capacitors, such as CL21/CL11.
2. Use professional equipment to test.
CL capacitors and CBB capacitors have little difference in appearance, but the electrical properties of loss are quite different. The loss of CBB capacitor is smaller than that of CL capacitor. Under the condition of 1kHz frequency, the loss tangent value of CBB capacitor is generally less than 0.001, while the loss tangent value of CL capacitor is less than 0.01. We can use professional instruments to test the loss value of the capacitor. Through the loss value, it is easy to see what kind of material the capacitor is used.
