Film capacitors, or film dielectric capacitors, are electrical components that store and regulate energy using a thin sheet or film as a dielectric material. This type of capacitor has a wide range of applications, from small electronic circuits to large industrial applications. The BFC237049473 model is a film capacitor that is designed for high reliability, low voltage power supply applications. This article will discuss the application field and working principle of the BFC237049473 model.

Application Field

The BFC237049473 is a surface mount, low voltage, low profile film capacitor. It is designed for use in high reliability, high temperature applications such as motor control systems, AC/DC converters, home appliances, medical electronics, power supplies, and automotive electronics. The capacitor is UL approved and has an operational temperature range of -40°C to +105°C. It is RoHS compliant and has a maximum load voltage of 385VAC. The capacitor is available in four different size options, including 4mm x 5mm, 5mm x 7mm, 6mm x 8mm, and 8mm x 10mm.

Working Principle

The BFC237049473 model is a non-polarized zeolite film capacitor with a self-healing, dielectric film. It is designed to provide a high ripple current rating and a low ESR over a wide temperature range. The zeolite film is steatite, which is a ceramic made of silica, soda ash, and dolomite. The steatite ceramic acts as the dielectric in the capacitor, with the terminals providing the contact for the two electrodes. The capacitor stores energy by creating an electric field between the two electrodes, which then slowly releases this energy in the form of a current. This is known as capacitance, and is measured in Farads. The film is coated with an electrode material to control the capacitance, and this coating is usually composed of metal oxides, such as tin oxide, nickel oxide, or cobalt oxide.

The BFC237049473 is also designed with a self-healing and flexible dielectric that is capable of withstanding high currents, temperature, and voltage. The dielectric has a low dielectric loss factor, which ensures stable performance and minimal dissipation. The self-healing feature helps protect the capacitor from being damaged by surges or spikes in current or voltage. The capacitor is also designed with a low thermal resistance, which allows for efficient heat dissipation, ensuring the capacitor has a long life.

The BFC237049473 model is an ideal choice for applications requiring high reliability, low voltage, and energy efficient operation. It is designed to provide reliable performance and long service life for a wide range of applications in the fields of motor control, AC/DC converters, home appliances, medical electronics, power supplies, and automotive electronics.
