(1) Rated voltage VR

The rated voltage VR is the DC voltage that the capacitor is designed to withstand and is printed on the product body. For aluminum electrolytic capacitors, the rated current

The voltage of 100 V is usually called "low voltage" capacitor, while the rated voltage > 100 V is called "high voltage" capacitor

(2) Operating voltage VOP

The capacitor can work continuously under the whole rated voltage (including superimposed AC voltage) and within the rated working temperature range. Continuous work

The allowable voltage range is between 0V and rated voltage. The capacitor can withstand reverse voltage less than 1.5V for a short time

(3) Surge voltage

Surge voltage is the maximum voltage applied to the capacitor in a short time, such as 10 times in an hour. IEC 60384-4 defines surge voltage as

Below: if VR ≤ 315, V: vs = 1.15 times VR; if VR > 315, V: vs = 1.10 times VR

(4) Instantaneous voltage

Some capacitors produced by kaiqijia can withstand voltage pulse exceeding surge voltage vs. Because the customers requirements vary with the application,

Kaiqijia does not declare that the general rating meets the overvoltage capacity required by the customer.

(5) Superimposed AC voltage, ripple voltage

Superimposed AC voltage or ripple voltage applied to aluminum electrolytic capacitor:

The sum of DC voltage and superimposed AC voltage shall not exceed the rated voltage, and shall not exceed the rated ripple voltage, and shall not reverse polarity.

(6) Reverse voltage

Aluminum electrolytic capacitors are polar capacitors. If necessary, a diode should be connected to ensure that the voltage will not be reversed. The conduction of diode

The electric voltage shall not exceed 0.8V. Reverse voltage lower than 1.5V can be applied for no more than 1 second, but continuous or repeated application is not allowed.
