Film capacitors are electrical components primarily used to store energy in an electronic circuit. The general design of these capacitors is based on thin film dielectrics that come in a wide variety of sizes and shapes. The specific type of film capacitor used in electronic applications is often determined by its application and the environment in which it will be used. One such example of a film capacitor commonly used is the FCN1913E273K.

The FCN1913E273K film capacitor is a non-inductive, axial leaded device that is designed to provide excellent frequency characteristics and high temperature stability. It is an electrolytic type capacitor that is capable of handling up to 100 VDC of power. The device is constructed from an oxi-doped polyester film which has a layer of tin-copper foil applied to either side. The film is wound into a cylindrical shape and connected to two nickel-plated brass terminations which provide a high degree of electrical conductivity.

The FCN1913E273K capacitor is primarily used in applications where low noise and minimal impedance are desired. This makes it an optimal choice for timing circuits, dynamics processors, and high-power audio amplifiers. In addition, it is also notably used in DC-to-DC converters, high power pulse circuits, communication equipment, and computer operating systems. The device is rated for operation at temperatures of -55 to +105 degrees Celsius and can withstand a maximum of 4.5 volts of peak-to-peak ripple current.

The FCN1913E273K capacitor utilizes a unique calendering process which provides significant advantages over traditional film capacitors. This is done through the application of a special silicone-based resin coating to the film dielectric prior to winding. The resin coating serves to help both prevent moisture absorption and reduce dielectric losses due to thermal stress, which helps to ensure that the capacitor is reliable and functions optimally when in use. Furthermore, the resin coating also helps to minimize the chance of shorting or sparking, thus providing further reliability and safety benefits.

The working principle of the FCN1913E273K capacitor is relatively straightforward. In simple terms, the device operates by controlling the amount of electrical charge that can be stored in it at any given moment. This is achieved by passing an electrical current through the device, which causes the dielectric materials within it to polarize and create an electrical field. This field in turn causes the metal plates within the capacitor to become charged, thus resulting in the accumulation of electrical energy. This process is generally referred to as dielectric polarization, and is what allows the capacitor to store electrical energy for later use.

In conclusion, the FCN1913E273K film capacitor is a reliable and effective device specially designed to provide excellent frequency characteristics and high temperature stability in a variety of electronic applications. Its unique calendering process and electrical field control makes it an optimal choice for low noise, minimal impedance applications, such as timing circuits, dynamics processors, and high-power audio amplifiers.
