Should check what to get when metallized film capacitors

Capacitors are not conventional daily necessities, no problem can be installed and used. When we get metallized film capacitors, we should check them, because it will be very troublesome if there is a problem. The quality of metallized film capacitors is checked before metallized film capacitors are used to prevent unsuitable capacitors from being loaded into the circuit.

When installing small-capacitance capacitors and high-frequency circuit capacitors, use a bracket to lift the capacitors to reduce the influence of distributed capacitance on the circuit. Note that the time for soldering metallized film capacitors is not too long, as the soldering temperature that is too long will pass through the electrode pins to the internal medium of the capacitor, causing the properties of the medium to change.

If the purchased metallized film capacitors are stored, it is dangerous to use the rated voltage directly when it is used after long-term storage. The correct method of use is to first add a small operating voltage, and then gradually increase the voltage until the rated voltage and maintain it for a short time at this voltage before putting it into use.

When capacitors are installed in the circuit, the metallized film capacitors are mounted in an easy-to-view location for easy verification and repair. When the capacitors are used in parallel, the total capacitance is equal to the sum of the capacities, but it should be noted that the working voltage of the metallized film capacitors in parallel cannot exceed the low rated voltage.

In order to avoid this happening, we have to test the appearance of metallized film capacitors before going to the machine. If there are technical problems with metallized film capacitors, we will try our best to solve them for you. We sincerely serve every customer who comes to consult, and the quality of capacitors is our basic commitment.
