Special attention to the use of film capacitors

With the development of technology, the renewal cycle of electronics, household appliances, communications and other industries is becoming shorter and shorter. With its good electrical performance and high reliability, film capacitors have become indispensable electronic components to promote the renewal of these industries. When using film capacitors, what problems need our special attention? Let's look at them with the editor.

It is known that the impedance of film capacitors is inversely proportional to the frequency, and the loss increases with the increase of the frequency. Measures should be taken to limit the harmonics and inrush currents in the circuit. film capacitors must always produce heat, pay special attention to ventilation cooling, reactive power compensation device installed, during the trial run, to detect the system, found that overvoltage, overcurrent, oscillation, harmonics and other timely measures to be taken, which is very necessary for the normal operation of capacitors.

As a professional film capacitor manufacturer, we will inspect, screen, capacity, loss, voltage withstand and insulation of the main indicators of capacitor components before leaving the factory, the appearance of the inspection is qualified before allowed to leave the factory.
