Product Description


CBB21/CBB22 polypropylene film capacitors are high - performance electronic components. They are fabricated with a polypropylene film as the dielectric material, which is metallized on both sides to form electrodes. These capacitors are encapsulated in a plastic case, providing mechanical protection and electrical insulation. They are designed to offer stable electrical performance and reliable operation in a wide range of applications.



Features

 
  1. Low Dielectric Loss: The polypropylene film dielectric has a very low loss tangent, minimizing energy dissipation and heat generation during operation. This results in high - efficiency energy transfer and better performance in circuits.
  2. High Insulation Resistance: With excellent insulation properties, these capacitors have extremely high insulation resistance, reducing leakage current and ensuring long - term reliability.
  3. Self - Healing Property: In case of a dielectric breakdown, the self - healing mechanism of the polypropylene film can automatically repair the damaged area, preventing permanent failure and enhancing the capacitor's lifespan.
  4. High Dielectric Strength: They can withstand relatively high voltages without breakdown, making them suitable for use in high - voltage circuits.
  5. Stable Capacitance: The capacitance value remains stable over a wide range of temperatures, frequencies, and applied voltages, ensuring consistent performance in different operating conditions.



Applications

 
  1. Power Supply Filtering: Used in power supply circuits to filter out ripple and noise, providing a clean and stable DC voltage.
  2. Coupling and Decoupling: In amplifier circuits and other signal - processing circuits, they are used to couple AC signals between stages and decouple DC bias, ensuring proper signal transmission.
  3. Resonant Circuits: Ideal for use in resonant circuits such as LC resonant circuits in radio frequency (RF) applications, where they help to determine the resonant frequency and improve circuit selectivity.
  4. Snubber Circuits: Employed in power electronics to suppress voltage spikes and protect other components from high - voltage transients.
