There are two steps for testing film capacitors: manual and fully automatic sorting machine. Automatic sorting machine to test the electrical properties of film capacitors: Now, sampling film capacitors only needs to examine a few samples of the capacitors. A film capacitor automatic sorting machine is required to complete the examination.
Reliable film capacitor manufacturers will pay attention to the quality of the finished products, and constantly carry out quality inspections and screenings in the process to ensure that consumers receive flawless products.
Although a fire-retardant flame-retardant material, a combustion-supporting epoxy or an outer casing, is used in the outer casing of the film capacitor, the external high temperature or flame can deform the capacitor core to cause package cracking, causing the capacitor core to melt or burn. The capacitor is rated for use at a temperature of 85 °C.
Some film capacitors with a rated voltage of 630V are actually rated at 400V. After the voltage is false, customers feel that the price is much cheaper. , in fact, there is a great risk in the use of capacitors, which will also cause the life of the capacitor to be shortened.
The gold spray of the film capacitor should use a quinary alloy or a hexavalent alloy, so as to ensure the electrical performance of the capacitor. In order to save cost, inferior film capacitors will use pure zinc spray gold. Although the cost is lower, the probability of quality problems in the capacitors increases. 3) The difference of CP line.
