1. Used capacitors can no longer be used, but can be removed as a periodic inspection to test electrical performance;
2. If the capacitor is charged, discharge it with a resistor of about 1kΩ before use;
3. If the capacitor is stored under conditions of more than 35 ° C and humidity greater than 70%, the leakage current may rise, and the rated voltage may be applied by a resistor of about 1 kΩ before use;
4. Confirm the rated capacity, voltage and polarity of the capacitor before installation;
5. Do not use capacitors that fall on the ground;
6. Do not use deformed capacitors;
7. The positive and negative lead spacing of the capacitor should match the position of the PC board soldering hole. If the capacitor is forcibly inserted into a circuit board whose hole pitch is not matched, stress will act on the lead wire, which may cause the capacitor to short-circuit or increase the leakage current;
8. Insert the capacitor pins or solder pins into the PC board during installation until the bottom of the capacitor is attached to the surface of the PC board.
9. Do not apply more than the specified mechanical pressure. When a pulling force is applied to the capacitor lead-out line, the pulling force acts on the inside of the capacitor, causing a short circuit inside the capacitor, and an open circuit or leakage current rises. The capacitor is soldered to the board and the capacitor is not shaken strongly.
