Several precautions for metallized polypropylene film capacitors

It is suitable for starting and running single-phase motors with a frequency below 100 Hz, and is widely used in single-phase motors such as water pumps, washing machines, cleaning machines, lawn mowers, and air compressors.

Precautions:

Not for use in high frequency circuits.

Before use, you should confirm whether the internal resistance of the capacitor, the dielectric strength of the medium, and the working voltage meet the requirements.

During testing, an alternating current of 2 times the rated voltage must be used, and 0.5~1 times the rated current must be maintained for testing.

Do not use it when the temperature is lower than -40℃, the ambient temperature is -10~50℃, and the humidity is below 90% RH.

Avoid prolonged exposure to the sun, do not use it in the rain, and do not allow the capacitor to be rinsed or soaked with water.

Do not exceed rated current

If your application requires more than the capacitor's current rating, then you may need to replace the capacitor. Because the actual operating voltage of the capacitor may be lower than its rated voltage, using a capacitor exceeding the rated voltage may cause breakdown or damage.

Avoid frequently connecting capacitors to excessive currents

Capacitive components may be damaged due to excessive current. So if you need to do any work with very high currents, make sure you connect the capacitor correctly.

If you need to use wire as a circuit for a capacitor, then make sure the wire does not exceed the length of the capacitor. If you need to use longer lines, make sure there are no excessively long wires between the capacitive element and other devices.

Avoid connecting capacitors with high-frequency equipment and high-power circuits

If you are using a high frequency circuit then make sure you connect it to other circuits. This can cause breakdown within the capacitor, which will cause damage to other components in the system.

Avoid using inductive windings and other components

If you are using an inductor coil, make sure you are using the appropriate size inductor winding. This may cause damage to the capacitive element, especially if the capacitive element is connected in series with the winding. If you find that the capacitive element is damaged, try disassembling or replacing it.

Avoid direct connection to high-voltage electrical equipment

If you need to connect high-voltage electrical equipment to a capacitive element, make sure the capacitor has sufficient dielectric strength on the high-voltage electrical equipment. If the capacitor is connected directly to high-voltage electrical equipment, it may cause an internal short circuit or breakdown. Therefore, if you need to connect a capacitor to high-voltage electrical equipment, make sure the connection is reliable and safe.
