3. Applied Voltage
1. Do not apply a voltage to the capacitor that exceeds the rated voltage as called out in the specifications.
ꢀ1-1. Applied voltage between the terminals of a capacitor shall be less than or equal to the rated voltage.
(1) When AC voltage is superimposed on DC voltage, the zero-to-peak voltage shall not exceed the rated DC voltage. When AC voltage or pulse voltage is applied, the peak-to-peak voltage shall not exceed the rated DC voltage.
(2) Abnormal voltages (surge voltage, static electricity, pulse voltage, etc.) shall not exceed the rated DC voltage.
Typical Voltage Applied to the DC capacitor
DC Voltage
DC Voltage+AC
AC Voltage
Pulse Voltage
(E:Maximum possible applied voltage.)
ꢀ1-2. Influence of over voltage
Over voltage that is applied to the capacitor may result in an electrical short circuit caused by the breakdown of the internal dielectric layers. The time duration until breakdown depends on the applied voltage and the ambient temperature.
1-3. Moisture Proof (Application: GQM033 rated voltage 200V products)
To prevent the migration and degradation due to flux residue when a voltage more than DC100V is applied to the capacitor, keep parts under low moisture condition with resin coating and the equivalent.
