The XHCC-4/40Y is a pulse energy storage capacitor: it stores the charging energy of a small-power power supply over a certain time interval, and releases that stored energy quickly within a very short interval at the moment it is needed, forming a strong impact current and a strong impact power. It is mainly used in high-voltage impulse discharge test, high-energy physics, oscillation circuits, geological prospecting and other fields.
How It Works
In use, the capacitor is charged from a small-power supply over a controllable time interval. When the moment of need arrives, the stored energy is released quickly within a very short interval, so the capacitor delivers a strong impact current and a strong impact power to the discharge circuit. That fast, concentrated release is what makes it suitable for high-voltage impulse discharge test, high-energy physics, oscillation circuits and geological prospecting.

Precautions and Common Faults
Handle and use with care
1. It is strictly forbidden to hit or collide with the high-voltage pulse capacitor, otherwise the internal film is easily damaged.
2. When using pulse energy storage capacitors, read the instructions and the content of the capacitor label to prevent overvoltage use.
3. During use, pay attention to the withstand voltage and safety distance of the connecting wire.
4. After the test is completed, the high-voltage end must be fully discharged.
5. During use, if there is an abnormal sound inside the capacitor, it is recommended to stop using it, as there is a risk of internal insulation damage.
6. If there are bulges on the capacitor shell, it is recommended to stop using it, as there is a risk of deterioration of the internal material and reduced insulation.
Frequently Asked Questions
Q1. What is the XHCC-4/40Y used for? It is a pulse energy storage capacitor. It stores the charging energy of a small-power power supply over a certain time interval, then releases that energy quickly within a very short interval to form a strong impact current and a strong impact power. It is mainly used in high-voltage impulse discharge test, high-energy physics, oscillation circuits and geological prospecting.
Q2. What do the numbers in the model XHCC-4/40Y mean? The number 4 stands for the rated capacitance, 4 µF, and the number 40 stands for the rated voltage level, 40 kV.
Q3. What are the working environment limits and the capacitance accuracy? The ambient temperature range is -20 to +50 ℃ and the working altitude is up to 2000 m (if it is greater than 2000 m, this is explained separately). The capacitance error is ±5%.
Q4. What safety precautions must be followed when using it? Do not hit or collide with the high-voltage pulse capacitor, as this can easily damage the internal film. Read the instructions and the capacitor label to prevent overvoltage use, and pay attention to the withstand voltage and safety distance of the connecting wire during use. After the test is completed, the high-voltage end must be fully discharged.
Q5. When should I stop using the capacitor? Stop using it if there is an abnormal sound inside the capacitor, as there is a risk of internal insulation damage; and stop using it if there are bulges on the capacitor shell, as there is a risk of deterioration of the internal material and reduced insulation.
