Film capacitors are passive electrical components used to store electric charge. They differ from electrolytic capacitors in that they are of relatively low voltage, typically below 20V. The R46KI3100DQM1M is one of the types of film capacitors from the Panasonic brand. This article will discuss its application field and working principles.

Applications

The R46KI3100DQM1M is a film capacitor with an insulation material composed of polyester, suitable for use in various electrical circuits due to its high heat and moisture resistance. Applications for these types of capacitors include decoupling and filtering, where they are used to reduce or eliminate electrical noise from a circuit. This type of capacitor is also used as an energy-storage element in motor starters and in combination with power relays. The wide working temperature range of -55 to +105 C makes it suitable to be used in outdoor equipment such as air conditioners and solar power systems, as well as in industrial machinery.

Working Principle

The R46KI3100DQM1M has a metalized polyester-film as the dielectric. When an electric field is applied, metal molecules in the film are polarized, creating a parallel electric field between metal layers. This electric field not only stores energy, but also blocks undesirable high frequencies. The stronger the applied electric field, the higher the capacitance value. This type of capacitor has a capacitance tolerance of ±20%, with a rated temperature range of -55 C to +105 C. It has a temperature coefficient of ±15%, so its capacitance value changes slightly with temperature.

Conclusion

The R46KI3100DQM1M is a film capacitor from Panasonic that is suitable for use in a variety of applications due to its heat and moisture resistance. As it has a wide working temperature range, it is suitable for use in air conditioners, solar power systems, industrial machines, and more. This type of capacitor has a metalized polyester-film as the dielectric, which polarizes metal molecules in its electric field when applied. Its capacitance changes slightly with temperature, has a capacitance tolerance of ±20%, and a temperature coefficient of ±15%.
