F161WP104K250V Capacitors

Film Capacitors

Film capacitors, also known as plastic film capacitors, polypropylene film capacitors, polyester film capacitors, and polystyrene film capacitors, are a type of capacitor that utilizes organic polymers as a dielectric material. Film capacitors employ a thin polyester (Mylar), polypropylene (PP), polystyrene (PS), polycarbonate (PC) or polyphenylene sulfide (PPS) film as a dielectric layer between two metal plates. A film capacitor\'s design, construction, and performance characteristics are optimized by selecting the type, thickness, width, and length of the film and the type of electrodes.

F161WP104K250V Application Field and Working Principle

The F161WP104K250V is a film capacitor specifically designed for industrial and instrumentation applications. It is constructed with a polypropylene film dielectric that is encapsulated in a phenolic resin case. It features a metalized surface for superior dielectric contact and high capacitance stability.

The F161WP104K250V capacitor has a wide range of applications and can be used in a variety of circuits, including power supplies, switched power supplies, switching regulators, frequency control circuits, instrumentation circuits and resonant circuits. Its high performance and reliability make it an ideal choice for these applications.

The working principle of a film capacitor is based on the principle of a parallel plate capacitor. The two electrode plates are separated by a dielectric material and the electric field between them produces an electrical current. This electrical current is stored in the form of energy in the electrostatic field between the two plates. As more current flows through the capacitor, the energy stored in the electrostatic field increases. This increase in stored energy increases the capacitance.

The F161WP104K250V capacitor has a temperature coefficient of less than 0.1%/°C, making it highly stable over temperature. It also has a low parasitic impedance and a low dissipation factor, making it relatively insensitive to humidity and vibration. It is also highly resistant to shock, vibration, and moisture. These characteristics make it an ideal choice for demanding applications.
