BFC237518202

Film capacitors, also known as plastic film capacitors or dielectric film capacitors, are a type of capacitor that uses plastic film as the dielectric. The dielectric material provides a combination of stable electrical features that may not always be found in the other capacitor types, such as electrolytic capacitors and ceramic capacitors.

The model BFC237518202 is a surface mount film capacitor made of high-grade polypropylene film that is molded into a compact package with a very small head. It has a wide operating temperature range of -55°C to 125°C, making it suitable for a variety of applications across different industries. Its rated capacitance is 0.047uF, with a rated voltage of 27V DC and a rated temperature of 85°C.

The design of the BFC237518202 film capacitor makes it ideal for use in critical electronic circuits where high levels of electrical performance and reliability are required. The capacitance of the device can remain stable even under conditions of extreme temperature, voltage, and frequency. This is because the polypropylene film that forms the dielectric has a high dielectric constant and low dielectric loss.

The BFC237518202 film capacitor is widely used in a variety of applications, including automotive electronics, avionics, defense, and industrial applications. In automotive applications, the device is used in safety circuits, noise reduction systems, and airbag control systems, providing reliable capacitance stability in the harsh automotive environment. The device is also used in avionics applications, where its high stability under extreme temperatures and humidity makes it ideal for use in sensor circuits, data acquisition systems, and frequency correction circuits.

In industrial applications, the BFC237518202 film capacitor is used in resonant circuit designs, as the capacitor provides a stable operation even when subjected to high temperatures and high vibration conditions. In defense applications, the device is used for high-voltage discharge, countermeasures, electro-optical systems, and other applications. The device is also found in many consumer electronic products, such as TV sets, DVD players, and home theater systems.

The working principle of the BFC237518202 film capacitor is based on the good, stable electrical characteristics of the polypropylene dielectric film. When a voltage is applied to the device, an electrostatic field is created, which results in a dielectric polarization. The polarization of the dielectric causes the device’s capacitance to increase. When the applied voltage is removed, the electric field dissipates and the device’s capacitance returns to its original value.

In conclusion, the BFC237518202 film capacitor is an excellent choice for applications that require stable electrical performance and reliability in harsh environments. The device’s compact size and wide operating temperature range make it suitable for a variety of industries, including automotive, aviation, defense, and industrial applications. The working principle of the device is based on the good electrical characteristics of the polypropylene dielectric film, which provides reliable capacitance stability under extreme temperatures and conditions.
