Description

Electronic components CL21 400V 223 capacitor manufacturers

Electronic components CL21 400V 223,a polyester film capacitor, also known as a Mylar capacitor, is a type of capacitor that uses a thin polyester film as the dielectric material. The polyester film is sandwiched between two metal plates, typically made of aluminum, which serve as the capacitor’s electrodes.

Since the medium between the two poles of the capacitor is not an absolute insulator, its resistance is not infinite, but a finite value, generally above 1000 megohms. The resistance between the two poles of the capacitor is called the insulation resistance, or leakage resistance. The smaller the leakage resistance, the more serious the leakage. Leakage of capacitors will cause energy loss, this loss not only affects the life of the capacitor, but also affects the operation of the circuit. Therefore, the larger the leakage resistance, the better.

Here are some key features and characteristics of polyester film capacitors:

  1. Dielectric Material: Polyester film capacitors use polyester (polyethylene terephthalate or PET) as the dielectric material. Polyester is a good insulating material with good electrical properties.
  2. Capacitance Range: The capacitance range of polyester film capacitors can vary, but they are typically available in a range of picofarads (pF) to microfarads (µF).
  3. Voltage Rating: Polyester film capacitors usually have voltage ratings ranging from a few volts to a few hundred volts.
  4. Tolerance: The tolerance of polyester film capacitors specifies the acceptable variation in capacitance from the rated value. Common tolerances include ±5%, ±10%, and ±20%.
  5. Temperature Stability: Polyester film capacitors generally offer moderate temperature stability, with operating temperature ranges typically spanning from -40°C to +85°C.
  6. Non-Polarity: Polyester film capacitors are non-polarized, which means they can be connected in either direction in a 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.
