Film capacitors, which are also known as plastic film capacitors or polypropylene capacitors, are made from a thin film of plastic, usually polyester or polypropylene. They are made up of a thin dielectric film that is followed by a series of metallic electrodes. The electrodes act as plates in the capacitor, forming a flat contact surface for electrical connection. Film capacitors have several advantages over other types of capacitors, such as having a very low equivalent series resistance (ESR) and being highly stable and reliable over time.

The B32796G8146K is a polypropylene film capacitor, designed to meet the rigorous requirements of high reliability applications. It is a radial leaded electrolytic capacitor suitable for a variety of demanding applications. It has a voltage rating of 400VDC and a capacitance of 3.3μF

Application Fields:

The B32796G8146K is primarily used in automotive, medical and military applications, where high reliability, stability and long life are essential requirements. Automotive applications include power supply filtering and AC circuits, power supply decoupling and pulse power supply decoupling. The medical applications include medical X-ray equipment, ultrasound and medical imaging equipment. Military applications include radar and communication systems.

Working Principle:

The working principle of the B32796G8146K is the same as any other capacitor. When a voltage is applied to the capacitor, most of the electric charge accumulates on the plates, leaving a small amount of charge on the dielectric film. The electric field created between the two plates causes the charge carriers to ionize and migrate to the oppositely charged plates, thus storing the electric charge. The film capacitors have a relatively low ESR, making them ideal for AC applications, since they can reduce the amount of energy lost as heat due to the electrical contact resistance.

The B32796G8146K is designed for use in high reliability applications, where reliability and stability are essential. It has a high temperature grade rating, which ensures that it can withstand extreme temperatures. Additionally, the capacitor has an adjustable capacitor discharge voltage, allowing for precise control of the voltage rate.

The B32796G8146K is a reliable and high quality polypropylene film capacitor, making it suitable for a wide range of demanding applications. Its low equivalent series resistance (ESR) and adjustable discharge voltage make it an ideal choice for automotive, medical and military applications.
