Film Capacitors

BFC246968273 capacitors represent one of the classes of film capacitors used in wide range of electrical and industrial applications. Film capacitors have several advantages over other types of capacitors such as ceramic, tantalum and electrolytic capacitors. Film capacitors have very high capacitance, wide temperature range, low ESRs, high dV/dt capability, high reliability, and excellent stability over time and temperature. Additionally, they are non-polarized, have low dielectric absorption, low inrush current, and have low leakage current.

BFC246968273 Application Field

The BFC246968273 capacitors are designed for applications operating in the range of 0 to 250 Vdc. They are typcially used in power circuits requiring high capacitance, like high power supplies, voltage regulators, and frequency converters. These capacitors are also used in RF applications such as blocking, tuning, bypassing, and coupling applications, and in voltage rejection circuits. They are also used as damping capacitors in some audio applications as well as in many general application circuits. In addition, they are often used in fuel-cell powered aerospace and industrial systems to provide high power density, low profile design, and enhanced performance.

Working Principle

The BFC246968273 capacitors are non-polarized capacitors and consist of layers of metalized polyester film. They are constructed of two metalized layers with a dielectric layer in between. The two layers are arranged in roll-shaped electrodes which provide an extended plate area. The extended plate area allows for higher capacitance values without increasing the size of the capacitor. This type of capacitor stores energy in the form of an electrical field between the two metalized layers. The electrical field is generated by a current flowing through the capacitor and is dissipated when the current is stopped.

To reduce the ohmic and parasitic effects, the layers are encapsulated in self-healing metallized epoxy packaging. This packaging helps to reduce the amount of energy that is lost due to leakage or short circuits. Additionally, the encapsulation helps to protect the capacitor from environmental conditions such as humidity, shocks, and vibration.

The BFC246968273 capacitor is a great choice for power supply applications due to its high capacitance, wide temperature range, low ESR, and excellent stability over time and temperature. It is also a great option for RF applications, as its high current handling capabilities, low leakage current, and good frequency characteristics make it an ideal choice for use in blocking, tuning, bypassing, and coupling applications.
