WMF4S33K-F Capacitors

Film Capacitors

Film capacitors, also known as plastic film capacitors, are electrical components used to store an electrical charge. They are made up of thin layers of polymer dielectric material wrapped around a metallic core. The thin layers of dielectric are isolated from each other electrically, but capacitively couple with each other. This allows the film capacitor to have significantly higher capacitance than a single layer capacitor. Film capacitors are used in many electronic applications, including modulation, regulation, signal processing, protection, voltage measurement, and control. They are especially popular in high-frequency applications due to their excellent stability, low leakage current, and low dielectric loss. They are also typically more reliable than electrolytic capacitors and ideal for use in precision circuits.

WMF4S33K-F Application Field and Working Principle

The WMF4S33K-F is a polypropylene film capacitor designed for AC/DC power supplies and switching applications. It is a high-voltage, high-capacity capacitor with relatively low ESR value. It has a rated voltage of 2500VAC and a capacity of 30µF. The capacitor can work in a wide temperature range of -40°C to +85°C.

The working principle of the WMF4S33K-F is simple. The two thin layers of dielectric material are wrapped around the metal core and then sealed in the plastic outer casing. When electric current flows through the metal core, an electrostatic field is created between the two layers of dielectric material. This field has the effect of storing electrical energy. When a load is connected to the capacitor, the stored energy is released and transmitted to the load, allowing the capacitor to function as an energy storage device.

The WMF4S33K-F is ideal for use in power supplies, switching applications, motor control, decoupling, and power factor correction. It is an extremely reliable capacitor with excellent stability and low leakage current and dielectric loss. This makes it a great choice for precision circuits in high-frequency applications.
