Film capacitors, also known as plastic film capacitors, refer to capacitors that use plastic films as the medium for charge storage. The R46KN322040H1M is one of these film capacitors. It provides stable performance and excellent long-term reliability in demanding applications.

The R46KN322040H1M is designed for use in AC circuits, although it can also be used in DC circuits. It is rated for 400 VAC and a maximum ripple current of 40 mA, with a temperature rating of 85°C. It has a capacitance of 0.0032 µF and a rated dissipation factor of 0.0007. It is also a non-polar capacitor, meaning that it does not have a positive or negative terminal.

The R46KN322040H1M’s application fields include power electronics, appliances, lighting, aviation, and military use. Due to its capability to exhibit low ESL and ESL drift (change in equivalent series inductance), the R46KN322040H1M is an ideal choice for applications involving high frequency switching currents.

The working principle of a film capacitor lies in the fact that it is composed of two thin layers of a dielectric material with an electrode covering each side. When a charge is applied to one of the electrodes, electrons flow from the electrode across the dielectric layer and onto the other electrode. This creates an electric field which stores the charge and prevents it from dissipating. The capacitance of the capacitor is determined by the size of the dielectric layer and the type of dielectric material used. The more electrons that can be stored in a dielectric layer, the higher the capacitance.

The R46KN322040H1M film capacitor utilizes a polypropylene film as the dielectric material. This material has a permittivity of 2.2, meaning that it is capable of storing more charge than other materials such as polyester or paper, making it a great capacitor choice for applications that require high capacitance. The R46KN322040H1M is also designed with a mechanical construction that enhances the capacitors long-term reliability.

Overall, the R46KN322040H1M is a highly reliable, long-lasting and efficient film capacitor. It has a wide range of applications in AC and DC circuits, and its features and construction make it suitable for demanding applications. The R46KN322040H1M is a great choice for applications requiring high frequency switching currents, providing low ESL and ESL drift for reliable and stable performance.
