Film Capacitors

Film capacitors are passive electronic components that utilize thin film dielectrics to store electrical charge energy. The BF014D0123K is a polypropylene (PP) film capacitor manufactured according to DIN EN 60848-3 standards, and is suitable for radial, through-hole or SMD-mounting in audio systems, AC motor drives, and power factor correction circuitry. It is available in the standard 0.4 μF, 400V capacitance and voltage rating, and further versions with voltage and capacitance ratings as low as 0.001 μF and 10 V, respectively, are also available. The device is also UL approved for safety.

Application Field

The BF014D0123K is a multipurpose film capacitor suitable for a variety of applications. It can be used in audio and video systems, AC motor drives, power supplies, computer and communication systems, and a variety of other industrial and consumer applications. It is particularly well-suited for applications involving high voltages and high frequencies, such as in power factor correction circuits, inverter drives, and auto-start motors.

Working Principle

Film capacitors are non-polarized capacitors that utilise a thin film of dielectric material between two metal plates to store electrical charge. The dielectric material used in the BF014D0123K film capacitor is polypropylene, which is an excellent insulator of electricity and is relatively stable even when subjected to high voltages and high frequencies. Current flows through the metal plates, and the capacitance of the device is proportional to the amount of dielectric material between them.

The capacitance of the BF014D0123K is relatively constant with changing temperatures, and is stable over a wide frequency range. This makes it suitable for many types of high-power circuits, where it can serve as a buffer or filter for incoming or outgoing signals.

The BF014D0123K film capacitor is self-healing, meaning that it will resume normal functionality after short-term overstresses, such as spikes in voltage or current. This makes it an ideal choice for applications involving long-term, continuous power such as those in motor drives and PFC circuits, where the device can be relied upon to perform reliably for many years.
