Description

Factory direct supply CL21 film capacitor 0.27UF metallized polyester

Factory direct supply CL21 film capacitor

The number of capacitors marked on the Cl21 capacitor is the nominal capacity of the capacitor. There will be an error between the nominal capacity of the capacitor and its actual capacity.

Capacitors work reliably for a long time. The maximum DC voltage it can withstand is the withstand voltage of the capacitor, also known as the DC working voltage of the capacitor. If in an AC circuit, it should be noted that the maximum value of the applied AC voltage cannot exceed the DC working voltage of the capacitor.

FAQ

Q:Film capacitors have been wave soldered, lead-free soldered, about 200 degrees? High temperature can easily damage the capacitor or affect the life. Don’t know how this industry is controlled and handled? Is manual welding required? Is there a temperature limit in the capacitor specifications? Is the solder joint temperature or body temperature when labeling?

A:Hello, the temperature of the wave soldering peak of the film capacitor can be 275 ° C, which is also the temperature of the IEC standard, and the tin immersion time is 3S-5S. The other is the preheating temperature and time. Film capacitors can withstand this temperature. Does not affect electrical characteristics. The solderability temperature and soldering heat resistance temperature are stated in the specification approval book. The former is aimed at the solderability of capacitor pins, while the latter is about the influence of welding temperature on the characteristics of film capacitors.

Q: How to judge the quality of the film capacitor?

A: 1) Use a multimeter to test the resistance of the thin-film electricity. The two feet should be very high resistance. If there is a capacitance meter, measure whether the capacitance value matches the mark on the case.

2) Test performance at room temperature, including capacity, loss, insulation resistance, withstand voltage, ESR, etc.

3) Do simulated life test.
