Film Capacitors

Film capacitors, also known as polyester capacitors, are a type of capacitor that uses a thin plastic film as the dielectric. They are widely used in a variety of electronic applications due to their superior dielectric strength and high capacitance. The BFC247990229 is a film capacitor specifically designed to meet the harsh environmental conditions faced by industrial and automotive applications.

Application Field

The BFC247990229 capacitors are designed to meet the extreme environmental and operating conditions faced in industrial and automotive applications. These capacitors are capable of operating under temperatures up to 105°C and voltages up to 500V. They can withstand shock and vibration, making them a suitable choice for applications in harsh environments such as car engines, industrial motors, and power supplies. Furthermore, they are certified to UL, IEC, and CE standards, so they can also be used in medical and consumer electronics.

Working Principle

The BFC247990229 capacitors utilize a combination of plastic film and aluminum foil as their electrode layers to form an electric double layer. This double layer serves as an energy storage device, and allows the capacitor to store an electric charge when voltage is applied. When the voltage is removed, the capacitor slowly releases the energy stored in the form of heat. The amount of energy that the capacitor can store and the rate at which it can release it is determined by the size and thickness of the electrodes.

The capacitance of the BFC247990229 is high due to the large surface area of the electrode layers. The metal foil is coated with a film-forming compound to form a dielectric barrier between the two electrodes. This dielectric barrier acts as an insulator, preventing the capacitor from shorting out when voltage is applied. The dielectric also affects the capacitance of the device, with higher dielectric constants resulting in higher capacitance values.

The BFC247990229 capacitors are designed with high self-healing properties. This means that under normal operating conditions, the capacitor will be able to recover from minor mechanical fractures caused by shock and vibration. This ensures that the capacitor is able to withstand harsh environments without compromising reliability.

Conclusion

The BFC247990229 capacitors are designed specifically for harsh environment applications such as automotive and industrial applications. They offer high capacitance and are designed to withstand shock, vibration, temperatures up to 105°C, and voltages up to 500V. Additionally, they boast high self-healing properties, making them a reliable choice for a variety of applications.
