Things you should check after getting the metallized film capacitor

Capacitors are not ordinary daily necessities. We have checked them after getting the capacitors. If there is no problem, they can be installed and used. Otherwise, it will be very troublesome if something goes wrong. Therefore, we should check the metallized film capacitors after we get them. Before using metallized film capacitors, the quality of the metallized film capacitors should be checked to prevent capacitors that do not meet the requirements from being installed in the circuit.

When designing component installation, metallized film capacitors should be used, otherwise the temperature of the capacitor will be too high and cause premature aging.When installing small capacity capacitors and capacitors in high frequency circuits, brackets should be used to hold up the capacitors to reduce the impact of distributed capacitance on the circuit.It should be noted that the time for soldering metallized film capacitors is not easy to be too long, because the soldering temperature for too long will be transmitted to the internal medium of the capacitor through the electrode pins, thus causing the performance of the medium to change.

If the metallized film capacitors we purchased are not used for storage temporarily, then when they need to be used after long-term storage, the rated voltage cannot be directly applied, otherwise it will be dangerous.The correct method of use is to first apply a smaller working voltage, then gradually increase the voltage until the rated voltage and maintain it at this voltage for a not too long time, and then put it into use.

When installing a capacitor in a circuit, the mark of the metallized film capacitor should be installed in an easily visible location for verification and maintenance.When capacitors are connected in parallel, the total capacitance is equal to the sum of each capacity. However, it should be noted that the operating voltage of metallized film capacitors connected in parallel cannot exceed the lower rated voltage.

Before using the machine, we need to test the appearance of the metallized film capacitor, so as to avoid unexpected occurrences.If you have technical problems with film capacitors, we will try our best to solve them for you.
