Introduction To Film Capacitors

Film capacitors are passive components found in numerous electronic circuits. They are constructed by winding thin plastic films around a supporting structure. The plastic films are usually made of a type of electrically non-conductive polymers such as polypropylene or polyester. These films are encapsulated by epoxies or varnishes to ensure that the electrical elements remain intact.

Film capacitors are often used in place of other types of capacitors – such as ceramic, electrolytic, and tantalum – in electronic circuits requiring more precision and less noise. Since the films used in these components are highly stable and consistent, they can accurately regulate alternating current (AC) voltage signals. This type of capacitor can also be used to reduce harmonics or noises in a power supply.

BFC237875163 Application Field and Working Principle

The BFC237875163 film capacitor is a three-terminal polymer capacitor, specifically designed for higher frequency applications up to 1MHz. It is composed of a ceramic substrate with two winding layers of a high-performance plastic film, providing an enhanced capacitance stability over DC bias, ripple voltages, and temperature variations. The interface between the substrate and winding layers is also highly resistant to external forces such as mechanical shock and vibration.

The device has three connection pads – two for the low and high sides of the voltage source and one for common ground. To begin operation, a suitable DC voltage is applied across the two terminals and the capacitance created between them determines the operation rate. As the voltage changes, the capacitance gradually adjusts and maintains the signal for the desired output. This type of capacitance stability and low inductance make the BFC237875163 chassis film capacitor a great choice for power supplies, amplifiers, filtering, etc.

Advantages

Film capacitors are known for their high current carrying capacity, low electrical leakage current, high energy storage capability, and excellent capacitance stability. These features can be combined with other qualities like good environmental tolerance, high dielectric strength, low self-inductance, and high ESR for optimum performance. In addition, they can handle higher working temperatures and have excellent self-healing properties.

The BFC237875163 chassis film capacitor also offers a wide range of other advantages, such as high frequency stability, low noise, low ESR, and excellent heat dissipation. The device also has good vibration and shock resistance. Furthermore, it is lightweight, compact, and easy to install in tight spaces.
