Film Capacitors

Film capacitors, also known as film dielectrics, consist of a thin film of plastic material that serves as a form of insulation between the alternating current (AC) power source and the conductors. This type of capacitor is commonly used in industrial applications requiring high-frequency filtering, surge protection and switching of AC power. Film capacitors have lower thermal capacity than electrolytic capacitors, which means that they do not dissipate significant amounts of heat.

890324026020CS Application Field and Working Principle

The 890324026020CS Film Capacitor is a polypropylene-based capacitor with a rated working voltage of 250VAC. It is commonly used in applications requiring high frequency filtering, surge protection and switching of AC or DC power. This device is small in size and typically mounts directly to a PCB, making it ideal for space-saving applications that require a low-profile design. The 890324026020CS is also well-suited for motor speed control, frequency selection, and power transmission systems.

At its core, the 890324026020CS Film Capacitor is a two-terminal passive electrical device, meaning that it does not contain any active components. It stores electric energy in an electric field between two conducting plates, known as the plates of an electric capacitor. When an AC voltage is applied to the capacitor, an electric field is generated between the two plates, which stores electrical energy. The capacitor will then discharge its stored energy as the AC voltage changes. This discharge of energy is used to help control the flow of electricity in systems such as motors, power transmissions, and frequency selection.

The capacitance and working voltage of the 890324026020CS Film Capacitor can be adjusted based on the chosen film dielectric, which is typically polypropylene. The size of the capacitor and its footprint on the PCB are also adjustable depending on the application and design preferences. The 890324026020CS has an exceptionally low ESR (Equivalent Series Resistance) and will remain stable up to temperatures reaching 125 °C.

The 890324026020CS Film Capacitor is renowned for its high-temperature and vibration-resistant construction, making it an ideal choice for active, high-power industrial applications. Its stable performance characteristics make it suitable for a wide range of products, including filters, switching and motor speed control applications. With the help of this capacitor, today\'s industrial machines are able to reliably store and discharge polarized electrical energy in order to accomplish their tasks.
