BFC241833903

Film capacitors, also known as plastic film capacitors, are general-purpose capacitors consisting of a dielectric film and metal electrodes. The most common film capacitors consist of a length of plastic film between two metal electrodes. Film capacitors are commonly used in electronics applications, such as power supplies, audio amplifiers, and AC motors, and their advantages include low loss, low ESR, and long life. The BFC241833903 is a type of film capacitor from KEMET. This article provides an overview of the application and working principle of the BFC241833903.

Applications

The BFC241833903 features a 4.7uF capacitance, 10V DC voltage rating, and low ESR and ESL. It is suitable for applications such as digital cameras, MP3 players, portable PCs, PDAs, and VCRS. Additionally, the capacitor is designed to handle high ripple currents and withstand temperature changes while providing a long life. The BFC241833903 can also be used in motor drive and control circuits, audio amplifier circuits, switching power supplies, and lighting control circuits.

Working Principle

The BFC241833903 is an electrolytic film capacitor. It consists of two metal electrodes, one of which is a solid conductive layer on the plastic film. The other is a wire mesh that covers the plastic film and the solid conductive layer. The electrodes are separated by an insulating film. When a voltage is applied to the electrodes, electric charge is stored on the electrodes, creating an electric field in the insulating film between them. The electric charge on the electrodes then induces an electric field in the plastic film, resulting in the capacitance.

The BFC241833903 is designed to have low ESR and ESL, which means it can handle high ripple currents. It also offers low impedance, which is beneficial in applications that require high speed switching. The capacitor is also designed to withstand temperature changes, which ensures it has a long life.
