Working Principle:

A film capacitor is a type of capacitor that has a metalized film as the dielectric. This metalized film is composed of a thin oxide-coated aluminum or zinc film that has been metalized on one or both sides. When a voltage is applied to the capacitor, the thin oxide layer acts as an insulator, preventing electric current from flowing between the two conductive surfaces. This capacitance is determined by the thickness and material of the metalized film. The 184682K630RBA-F is designed to offer superior performance in high frequency applications due to its high self-resonant frequency.

The capacitor also features a temperature coefficient of -15 % from -55 °C to +85 °C and a DC working voltage of 630 Volts. It is suitable for use in audio systems, motor drives, and power supplies. It also features a high voltage transient energy rating which is more than 1.27 times higher than the standard axial-lead type film capacitor.

In summary, the 184682K630RBA-F capacitor from KEMET is a high quality polypropylene film capacitor. It is designed for use in various applications such as audio systems, switching power supplies, motors, fluorescent lighting, general-purpose AC, and communication systems. It provides excellent frequency and temperature stability, low loss, high ripple current capability, excellent temperature characteristics, and good insulation resistance. The high voltage transient energy rating and temperature coefficient rating make this capacitor well suited for use in high frequency and power applications.
