Film capacitors are a type of electrical component with a wide range of uses. The R46KI3470JBM1K is one such component, delivering reliable performance for a variety of applications. In this article, we explore the R46KI3470JBM1K’s application field and working principle.

What Is a Film Capacitor?

A film capacitor is an electrical component composed of two parallel conducting surfaces, separated by an insulating film. It is distinct from other types of capacitors in that the dielectric between the conductors is made of a thin polymer film, rather than a crystal, ceramic, paper, or wound metal. Additionally, its structural film-type design allows it to store a wide range of values, making it suitable for many applications.

The R46KI3470JBM1K Film Capacitor

The R46KI3470JBM1K is a film capacitor made by TDK, specifically designed for use in high-frequency and power conversion applications. It operates in a range of temperature, from -55 to 130C, and features a polyphenylene sulfide film that is both thermally and chemically stable. The low inner-resistance of this capacitor allows it to handle high-frequency switching without developing large currents or heat, making it ideal for various power circuits.

Application Field and Working Principle

The R46KI3470JBM1K Film Capacitor is suitable for a range of applications, including the following:

• Automotive power supplies, including those used to power infotainment systems, airbags, and other safety components.
• Switch mode power supplies (SMPS), which are used in numerous consumer electronics.
• Charging and discharging circuits, which are used to maintain the output voltage and current of a power supply.

Other applications for the R46KI3470JBM1K include personal computers, home appliances, and solar energy systems.

The working principle behind the R46KI3470JBM1K is simple. When an electrical potential is applied, a charge builds up between the two conductors; this charge is known as "capacitance." This capacitance is what allows the capacitor to store and release energy. When the voltage drops, the energy stored in the capacitor is released. This cycle is known as "charging and discharging," and it allows the capacitor to store and release energy as needed.

Conclusion

The R46KI3470JBM1K is a film capacitor designed for high-frequency and power conversion applications. Its low inner resistance and thermally-stable polyphenylene sulfide make it ideal for handling high-frequency switching without large currents or heat. Additionally, its wide range of applications include automotive power supplies, SMPS, and solar energy systems.
