Film capacitors, also known as Plastic Film Capacitor, Mylar Capacitor or Polyester Film Capacitor, are passive electronic components that are used to store energy in an electric field. Film capacitors are made of insulating plastic film, usually polystyrene, polycarbonate and other high-end materials, and can be welded, molded, printed, through hole, and surface mounted on printed circuit boards.

One such film capacitor is the 103PPA252KG. This film capacitor is mainly used in the high frequency/high performance filter circuit in high temperature, high humidity and other harsh environments. It is also suitable for AC frequency conversion, UPS systems, EMI interference attenuation, etc. The 103PPA252KG is suitable for working in environments with temperatures between -45C to 85C, and features a rated temperature of 105C.

The working principle of the 103PPA252KG is based on the principle of electrostatic capacitance. It stores electrical energy in the form of an electric field between two conductive plates insulated by an insulating medium. A voltage applied across the two conductive plates causes a charge imbalance across them, storing energy in the form of an electric field. As the voltage across the two plates changes, the charge imbalance is altered and the capacitor either absorbs or releases energy.

The 103PPA252KG uses a metallized polyester film as the dielectric material, with metalized aluminum foil as the electrodes and epoxy resin as the packaging medium. This capacitor has a wide frequency response that ranges from dc up to over 20kHz. It has excellent response characteristics, and can reduce insertion loss, transient response, high current density, low stray capacitance and its resonance behavior is very stable.

The capacitance value of the 103PPA252KG ranges from 0.1µF to 0.22µF. The rated voltage is rated at 100VAC or 160VDC, and features an extremely low ESR, making it suitable for high frequency applications. It has excellent long-term reliability with a temperature coefficient of 250ppm/ºC maximum.

The 103PPA252KG has many applications in various fields of technology such as consumer electronics, automotive electronics, medical and power systems, communications, RF amplifiers, switching power supplies, UPS systems and more. It is an ideal choice for use in high-end applications. It can be used for matching and differentiation in flyback, front-end rectifiers and as input output coupling capacitors in Switched-Mode Power Supplies.

In conclusion, the 103PPA252KG film capacitor is an excellent choice for high frequency/high performance filter circuit applications in harsh environments. Its wide frequency response makes it suitable for many different types of applications, while its excellent long-term reliability and low ESR make it a top choice for use in high-end applications.
