Film Capacitors

Film capacitors, also known as plastic film capacitors, are widely used due to their low price, stable performance, and good temperature characteristics. They are widely used in high- and low-frequency circuits for signal filtering, wave-shaping, and bypassing.

PHE450MK4270JR05 application field and working principle

The PHE450MK4270JR05 is a film capacitor made by Sonitron electronics. It is designed for use in high power and high temperature applications, such as motor-generator sets, AC induction motors, flameproof motors and switchgear.It has a wide range of applications in power, telecommunications and electronics.

The capacitance of the PHE450MK4270JR05 is 4.27uF, and its voltage rating is 450V. It is capable of handling up to 6.3A, making it suitable for high power applications. It is RoHS-compliant and has a long service life.

The PHE450MK4270JR05 uses a polyester film as the dielectric material. This film has a very low dissipation factor and offers excellent dielectric characteristics. It is designed to withstand high temperatures and is also moisture resistant. The capacitor case is made of phenolic resin, which insulates and protects the capacitor from mechanical damage and environmental hazards.

The capacitor’s working principle is based on the traditional capacitive circuit. When an alternating current is applied to the capacitor, it accumulates charge on its plates. This charge is then transferred to the output through a dielectric material, resulting in the output voltage. This process is repeated when the current changes direction. The capacitor will therefore pass the AC current, but block the DC current, resulting in a very efficient AC filter.

The PHE450MK4270JR05 is a reliable and cost-effective solution for high power applications. Its wide temperature range, high voltage rating and low dissipation factor make it ideal for demanding applications. Its robust construction and dielectric material also ensure a long service life.
