930C2P82K-F

Film capacitors, also known as film dielectric capacitors or plastic film capacitors, are a type of capacitor traditionally constructed using a thin plastic film as the dielectric, sometimes combined with paper as a carrier of electrodes, often with an electrolyte instead of a solid foil. Generally, the film capacitor is a surface-mounted component with multiple layers of conductors and dielectrics which are assembled in a vacuum environment. The layer configuration is designed to insure a very uniform electric field in which the dielectric is maintained in a lightly compressed state, thereby maintaining its structure and providing improved capacitive properties.

The 930C2P82K-F is a film capacitor developed specifically for use in a wide range of applications, most notably in AC line-connected power supplies, motor speed control, DC link systems, data acquisition systems, and DC/DC converters. In this capacity, the 930C2P82K-F is capable of reacting to abrupt input power changes while providing a reliable level of output voltage and current stability. The 930C2P82K-F also adds significant low-ripple filtering capabilities in addition to the high capacitance density of the film capacitor.

The working principle of the 930C2P82K-F is based on the process of dielectric charging and discharging. If an electric field is applied, the dielectric will be polarized (charge separation); in terms of capacitors, this polarization will result in the charge separation in the plates, leaving one side positively charged and the other negatively charged. The amount of charge stored is proportional to the applied electric field. When the electric field is removed, the dielectric will relax its polarization (discharging), i.e., the charges will be redistributed, returning to their original configuration.

The charge stored in the 930C2P82K-F can be used as a power source when a voltage drop is detected such that current flows and the charge stored is returned to the capacitor. When the capacitor is being charged, the voltage across it will increase, and when the capacitor is being discharged, the voltage across it will decrease. The capacitance value of the 930C2P82K-F is largely determined by the ratio of the plates’ surface area to the dielectric thickness as well its permittivity (or dielectric constant). This explains why the 930C2P82K-F is notable for its high capacitance density.

The 930C2P82K-F is available in a variety of voltages and capacitances, and is built with epoxy-coated construction for improved moisture and temperature control and improved performance characteristics. Its high frequency performance, low impedance, and excellent reliability make the 930C2P82K-F an ideal choice for applications that require stability and accuracy. When combined with the power of the other components of circuit, the 930C2P82K-F can provide a powerful and reliable platform for AC/DC and DC/DC switching power supplies, motor control, data acquisition, and DC link systems.
