Description

CBB21 metallized film capacitor for high frequency oscillation circuit

 

CBB21 metallized film capacitor is replaced by metallized polypropylene film non-inductive structure. It is made of tinned copper clad steel wire, flame retardant epoxy resin powder package sealed or plastic shell, filled with flame retardant epoxy resin. Its main uses are in a wide range of high-frequency, DC, AC and pulse circuits. It is suitable for color TV S correction circuit that requires small size and excellent performance. Electronic equipment resonance, power factor compensation of emergency lights, supplement of switching power supply, timing, oscillation circuit.

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.
