Introduction

Film capacitors, also known as film dielectric capacitors and plastic dielectric capacitors, are capacitors which use plastic materials such as polypropylene, polyester, Teflon for the dielectric. Best known as Metallized Polypropylene Film Capacitors (MPF), their advantage of compared with other types of capacitors is their good reliability, self-healing effect, high temperature and voltage stability, low dielectric absorption, low leakage current and long life. They are widely used in communication equipments, instrumentation, aerospace electronics, consumer electronics, audio-frequency, radio and other areas. BFC246968103, an Aluminium Electrolytic Capacitor with plastic film as dielectric, is a kind of very popular film capacitor due to its outstanding electrical properties and competitive pricing. In this article, we will discuss BFC246968103 application field and working principle in detail.

BFC246968103 Application Field

BFC246968103 is suitable for a variety of applications, such as electroacoustic equipment, DC power supply, radio, lighting and power management. By virtue of its high temperature rating of 105\'C and its good insulation properties, it is also a good choice for applications that require high voltage and high temperature performance.Generally speaking, BFC246968103 is used in DC, audio-frequency, video and digital circuits. In audio-frequency-related applications, it is mainly used for the circuit filter and frequency splitting. While in digital circuits, film capacitors are used for the stabilization of power supply and preventing noise interference generated by the power supply. For video applications, it can be used in amplifier output signal to filter high frequency wave interference in order to increase the image resolution. In addition to the above, BFC246968103 can also be used for the motor drive and vibration control, as the characteristic of good self-healing effects can help reduce mechanical vibration or pulse interference.

BFC246968103 Working Principle

BFC246968103 is based on the principle of a capacitor, which is composed of two electrodes separated by an insulator. The film capacitor is wound up with two metal electrodes. The insulator between the electrodes is a thin plastic film. Therefore, when an alternating current is applied between the two electrodes, the electromagnetic field generated by the current interacts with the insulator in order to generate an electric energy storage. When an alternating current is applied between the two electrodes, the electric charges will flow alternately between the two electrodes, resulting in a "vibrating" electric field kept around the capacitor. This "vibrating" electric field can absorb and store electrical energy, acting as a low-frequency filter and attenuating the interference signals with high-frequency and high-amplitude. In summary, BFC246968103 has a wide range of application field, mainly used for DC, audio-frequency, video and digital circuits. It works by utilizing the alternating current to generate an electric energy storage and a "vibrating" electric field that can absorb and store electrical energy.
