Film capacitors (sometimes called film dielectric capacitors) are a type of capacitor that uses a thin plastic film as a dielectric material. The film may be plasticized polyvinylchloride (PVC), polycarbonate (PC), polyester (PET or Mylar), polypropylene (PP) or various combinations of these. The electrodes of the capacitor are metallic layers, typically aluminum or zinc, deposited on the film. The capacitance of the capacitor depends on the size of the electrodes, the thickness of the film and the permittivity of the dielectric material.

ECQ-E10224KFB is a metallized polypropylene film capacitor for Power Electronic Applications. It features low loss, high current capability, excellent noise characteristics, and a low ESR. This component has a round body shape and available in various sizes from 10mm x 10mm to 20mm x 30mm. These capacitors are available in various ratings and voltage classes. The working temperature range is -55°C to +105°C.

The ECQ-E10224KFB is widely used in fixing common-mode and differential mode noise in Power Supplies and Electric Motor Drives. It is also used in AC Filters connected to industrial loads. The capacitor can also be used in high-current and high-voltage transient applications like fuel injectors or any high-current, low-voltage applications like switching devices. It is typically used in switching-mode power supplies (SMPS) where its low ESR, high ripple current handling identify it as a good choice for DC-link capacitors and filter capacitors.

The working principle of ECQ-E10224KFB is based on electric field theory. When a voltage is applied to the capacitor, the positive and negative charges are drawn to the electrodes on either side of the film. The electric field in the dielectric material, combined with the capacitor electrodes, builds a capacitor. The capacitance of the device is determined by the size of the electrodes, the thickness of the film and the dielectric constant of the film. The higher the dielectric constant, the greater the capacitance.

ECQ-E10224KFB film capacitors offer reliable operation and high dielectric strength, making them ideal for a wide variety of power electronic applications. With their superior temperature characteristics and high current capability, they are often chosen to provide exceptional performance in any application requiring precise noise filtering or voltage stability.
