In our company, withstanding voltage test is performed at 2.5 to 3 times (rated voltage < 100) or 1.2 to 2.5 times (rated voltage ≥ 100) of rated voltage. In case that the applied voltage exceeds the rated voltage and does not exceed the voltage mentioned above, ceramic capacitors are not broken instantly. However, it causes the reduction of reliabilities to use over the rated voltage. Please refer to following precautions in detail.
* Precautions of the calalog are here.
It is not guaranteed to use our products over the rated voltage. Please agree to that in advance.
