What to check when you get the film capacitors

Check after getting metallized film capacitors. If no problem, install and use. Otherwise, problems are easy to occur. Before using metallized film capacitors, check the quality to avoid capacitors that do not meet the requirements.

When installing small-capacity capacitors and capacitors for high-frequency circuits, brackets should be used to support the capacitors to reduce the impact of distributed capacitance on the circuit. Note: It is not easy to braze metal film capacitors for too long. Because the soldering temperature for a long time will be transmitted to the internal medium of the capacitor through the electrode pins, which will cause the performance of the medium to change.

If the purchased metallized film capacitors are not used temporarily, the rated voltage should not be applied directly after long-term storage, otherwise it is dangerous. Correct use method: first apply a small working voltage, and then gradually increase the voltage until the rated voltage is maintained at this voltage for not too long before putting it into use.

When capacitors are installed in the circuit, the logo of metallized film capacitors is installed in an easy-to-observe position for easy verification and maintenance. When the capacitors are used in parallel, the total capacitance is equal to the sum of the respective capacities, but it should be noted that the working voltage of the metal film capacitors in parallel cannot exceed the lower rated voltage.
