Case Study – Helping a Client Prevent Surge Failure

A client experienced repeated failures during surge testing of high-voltage equipment.

JEC Analysis

Failure analysis showed that the ceramic capacitors had insufficient voltage margin. Although they passed conventional voltage tests, repeated surge pulses could exceed the dielectric strength, resulting in insulation breakdown and system failure.

JEC Solution

JEC reviewed the client’s operating voltage and surge requirements and recommended high-voltage ceramic capacitors with sufficient voltage margin, with rated voltage options up to 50kV.

Beyond product performance, JEC provides:

Multiple international certifications: UL, VDE, CQC, ENEC, etc.

24/7 automated production: supporting stable and reliable delivery

Engineering support: helping clients select suitable specifications for demanding applications

After adopting the JEC solution, the client improved surge withstand capability and reduced repeated testing and troubleshooting during EMC validation.
