Film capacitors, sometimes called Polyester capacitors or Mylar capacitors, are electronic components designed to store electrical energy and later release it. The 930C2P47K-F is a film capacitor specifically designed for use in a wide range of applications and for various electrical needs.

Construction

The 930C2P47K-F consists of a polyester sleeve that holds a part number specific capacitance. Inside the sleeve are multiple layers of dielectric foil enclosed in metalized, plasticized, or non-metalized dielectric material. These materials act as the electrodes, insulators, and contacts while the dielectric layers work together to form an electrical field. The different layers of dielectric allow for a combination of high capacitance, low ESR, and higher pulse handling capabilities.

Applications

Primary applications for the 930C2P47K-F include power supplies, medical instruments, telecom equipment, and industrial equipment. Its high capacitance rating and low ESR make it suitable for a variety of power conditioning circuitry and risk reduction solutions, from multi-camera video surveillance systems and high power inverters to power supplies in servers and electronics. The capacitor is also ideal for motor control, especially for applications that require robust DC motor start and run performance. Additionally, it has been found to improve the performance of fuel cell power systems.

Working Principle

Generally, when a current passes through the 930C2P47K-F, it accumulates electrical energy and forms a potential difference between the two plates. This potential difference is capacitance which is typically measured in Farads. Capacitor\'s charging and discharging rates depend on the capacitor\'s construction. The capacitor\'s capacitance can be either a fixed or a variable value depending on the specific application. In fixed capacitors, the capacitance is fixed, while in the case of variable capacitors, the capacitance can be adjusted through the user.

One of the main advantages of using film capacitors over ceramic or electrolytic capacitors is their lower distortion for high frequency signals, as film capacitors generally have higher dielectric constants than other capacitors. Additionally, film capacitors offer excellent temperature stability, increasing their reliability when compared to other types of capacitors. Additionally, their high volumetric efficiency ensures that they can be made with small physical sizes, saving valuable space on circuit boards.

The 930C2P47K-F is a reliable and versatile capacitor that can manipulate current and protect circuitry in a variety of applications. Its low ESR, long life expectancy, and low cost make it a great choice for applications that need reliable performance. Film capacitors such as the 930C2P47K-F provide numerous benefits and are a durable, reliable, and cost-effective solution to many power conditioning needs.
