Film capacitors are used in a wide variety of applications, ranging from selecting and conditioning of power electronics and motors to filtering of electronic signals and providing noise reduction for data lines and low-level audio. The particular type of film capacitor called R46KI318000M1M, manufactured by the German-based company Steinel, is particularly adept at handling high power and frequencies, making it a choice capacitor for various applications.

Product Overview

The R46KI318000M1M film capacitor is a type of metal-oxide film capacitor, also known as foils. Each capacitor contains metalized film as its coating dielectric, as well as aluminum-zinc plating on its outer walls. This capacitor has a surface area of 0.0027 cm2, a leakage current of 0.018 microamperes, and a rated voltage of 4,000 volts, making it suitable for use in high voltage settings. The R46KI318000M1M also boasts an average thermal resistance of 68 degrees Celsius and a dielectric constant of between 1,300 and 2,500.

Application Field and Working Principle

The wide range of specifications offered by the R46KI318000M1M makes it ideal for a variety of settings. It is an excellent choice for high power applications, such as in variable speed motors, switching power supplies, and communications equipment. This is because it has a low resistance (-6.5dB), low losses (-6.5dB), and high frequency bandwidth up to 4GHz. Its high voltage rating also allows it to be used as a rectifier filter in X-ray machines, power distribution systems, and blast furnace systems, making it a reliable choice for both sensitive and demanding settings.

The working principle of the R46KI318000M1M is based on the use of capacitors that store electrical energy in the form of an electric field between two conducting plates separated by a dielectric material, also known as a dielectric film. The energy stored by the film capacitor is proportional to the surface area of the conductive plates and the dielectric constant of the film. This stored energy can then be discharged rapidly when needed, allowing the capacitor to act as a buffer or a surge suppressor, allowing the power system to work with greater stability.

Advantages

The R46KI318000M1M film capacitor offers numerous advantages over other types of capacitors, such as ceramic, electrolytic, and paper capacitors. One of its greatest advantages is its low equivalent series resistance, which allows it to produce high currents in high power applications without generating heat. It also has good heat dissipation characteristics and a robust construction, making it suitable for harsh environments, such as high temperature and humidity. Finally, the R46KI318000M1M is one of the most cost-effective film capacitors on the market, making it an appealing choice for users on a budget.

Conclusion

The R46KI318000M1M film capacitor is an excellent choice for a variety of settings, thanks to its high voltage rating, low equivalent series resistance, and robust construction. It is especially adept at handling high power and frequencies, making it an ideal choice for use in motors, power supplies, and communication devices. And because this film capacitor is also one of the most cost-effective models on the market, it is a compelling choice for users who need reliable performance without the hefty price tag.
