Film Capacitors are components that are able to store and then discharge electrical energy. They are commonly used in timing, tuning, filtering, bypassing and decoupling applications. The BFC237178183 is a film capacitor, and its application field and working principle are outlined in this article.

Introduction

The BFC237178183 is a film capacitor, which is composed of two electrodes separated by an organic dielectric or plastic film. This type of film capacitor is extremely reliable, showing excellent characteristics for a variety of applications including power electronics, motor control inverters, and many other applications.

Application Field

The BFC237178183 film capacitor is designed and manufactured for high-end high performance applications. The capacitor features a high temperature rating of 125°C, and its superior performance is ideal for power supplies, motor controls, and inverters that require high voltage and energy storage capabilities. Additionally, this film capacitor is designed for use in audio equipment, high-frequency amplifiers, power tools, automotive turbines, and various other industrial and civilian applications.

Working Principle

The BFC237178183 film capacitor uses an organic film dielectric that is stretched and rolled to form the capacitor body. The dielectric used is either polyester or polypropylene, and the dielectric constant is between 3 and 5. This allows the capacitor to store a large amount of electrical energy which makes it ideal for high power applications. The back-to-back electrodes are spaced apart with a thin dielectric rubbery material, which reduces parasitic capacitance and ensures low ESR values. In addition, the capacitor is designed with a protective coating which serves to increase its life expectancy.

When the voltage is applied to the capacitor, the electric field creates an electrostatic force that attracts charges from the dielectric into the capacitor\'s body. This causes the electrons to be drawn to the dielectric surface and with an increase in electron flow, the capacitor charge builds up. Once the applied voltage reaches a certain level, the capacitor is said to be saturated and will no longer be capable of storing additional charge, thereby preventing arcing.

The BFC237178183 film capacitor is designed to provide the highest quality performance for various applications. Its ability to store and discharge electrical energy makes it an ideal choice for applications such as motor control inverters, power supplies, and many other applications.
