Method for quickly judging the quality of ceramic capacitors

Everyone knows that every company will be equipped with a purchaser as standard. The model of the purchased product will be distributed to the purchaser by technical engineering, or directly purchased by the project. So how do we quickly judge the quality of ceramic capacitors, and then the editor tells you.

The method for judging the quality of ceramic capacitors is as follows:

1) Understand the specification parameters (rated value, capacitance value) of ceramic capacitors

2) Pitch length

3) Working temperature

4) Error

5) Whether the leakage current meets the standard

The measurement method of ceramic capacitor is as follows:

1) Ammeter test voltage and leakage current

2) aging equipment test high voltage ceramic capacitor parameters

3) Unblock the high-voltage ceramic capacitor to see the chip and capacitor foot material

Complicated experimental procedures must be performed by professionals, and reliability test reports can be provided to manufacturers who purchase capacitors! Different circuit requirements will have unused standard requirements, and as a purchaser, the quality of the ceramic capacitor is also determined, which can reduce unnecessary trouble. When the project is not in place, the purchasing personnel can deliver the test to the professional technicians in accordance with the method described above. I hope the content of this article can help you!
