Film capacitors are common passive components in electronic circuits. The BFC237513122 is a type of film capacitor. This type of capacitor is typically used as a signal coupling or bypass capacitor, as well as for other general applications.

The BFC237513122 capacitor is a multi-layer polyester capacitor with a pitch of 12.7 mm coil. Its rated capacitance is 0.0063uF-10KV, and its rated voltage is 10KV. The equivalent permittivity or dialectic constant of the dielectric is 4.3 with a temperature range of -25 to +85 Degrees Celsius. It features high insulation resistance, good frequency response, low leakage current, and low loss.

The construction of the BFC237513122 consists of several layers of non-crystalline polyester that are pressed and wound together. There is a thin layer of aluminum metal that is evaporated and placed between the layers to form the layer of capacitor film. This type of construction allows for extremely small capacitors allowing the use of space saving PCB designs while operating in a high temperature and voltage environment. This type of capacitor construction also offers superior ability to absorb strong electromagnetic interference (EMI).

The primary application fields of the BFC237513122 capacitor range from bypass capacitors, filter capacitors, and signal coupling capacitors, to lighting, fuse interlock capacitors, and others. The capacitor is also used in circuitry to slow down voltage transients, reduce high frequency noise, and prevent power surges.

The working principle of the BFC237513122 capacitor is based on the fact that when a voltage is applied to its leads, the dielectric between the plates causes the capacitor to store this charge (as electrical energy). When the voltage across the leads is then reduced or terminated, the electric energy will be discharged back into the circuit. As this occurs, the capacitance of the capacitor is seen as a resistance or impedance parallel to the load.

The BFC237513122 is well suited for a wide range of film capacitor applications. It offers high temperature and voltage resistant construction as well as superior EMI shielding. Its numerous application fields span from signal bypass, filter capacitors, and fuse interlock capacitors, to other general usage capacitors. Its working principle is based on the basic electrical properties of capacitors, allowing for constant current, voltage, and resistance as long as the capacitances of its dielectric remain constant.
