Film Capacitors

BFC237515913 is one of the most commonly used film capacitors. It is widely used in many industrial, communication, home appliances, automotive electronics and other fields.

Application Field

BFC237515913 capacitors are mainly used in low voltage circuits, especially in circuits such as surge absorbers, which require high voltage resistance and high temperature resistance. They can also be used in applications like inverters, relay circuits, and motor control to suppress EMI noise. In addition, it can be used as a PFC component for home electronic appliances. To achieve soft start or switching PFC, due to the small size of this component, it is ideal for mobile devices like mobile phones and tablets.

Working Principle

The BFC237515913 film capacitor is essentially an insulator with two electrodes. When power is applied to the electrode, the insulator begins to charge, and a dielectric medium is formed between the electrodes. This dielectric medium then stores electrical energy. The capacitor is composed of a dielectric film and a conductive metal film, which form a metal-oxide-semiconductor (MOS) field effect transistor (FET) structure. This MOSFET structure can control current flow and voltage across its terminals. The dielectric includes oxides such as titanium oxide, tantalum oxide, and other non-metallic oxides. The precise control of the dielectric thickness and insulation ensures that films can operate in a wide temperature range, from -40℃ to +85℃. The capacitance range can be very wide, from a few picofarads (pF) to several microfarads (μF).

In addition, BFC237515913 film capacitors have excellent noise suppression and low dielectric absorption characteristics. The dielectric absorption (DA) of this capacitor is very low, and the ripple current capacity is 3 times higher than ceramic capacitors. Furthermore, insulating materials can have an operating temperature range of -40℃ to +125℃, resulting in outstanding temperature and humidity stability characteristics compared to aluminum electrolytic capacitors.

Overall, BFC237515913 film capacitors have advantages in a wide range of applications, ranging from simple noise suppression to high-precision circuit design. In addition, its relatively small size, low cost, wide capacitance range, high reliability, and low temperature-dependent behavior make it ideal for use in various applications.
