Film Capacitors

Film capacitors, also known as polymer film capacitors or plastic film capacitors, are electrical capacitors that use a film of plastic as the dielectric medium. They have become popular due to their superior performance in many applications. Their high dielectric strength and low inductance values, as well as their ability to withstand high voltage, make them ideal for use in a wide variety of applications.

185153K400RFA-F application field and working principle

The 185153K400RFA-F is a device for electric signal processing and control, specifically designed for use in a wide array of DC power systems. It is an ultra-capacitor made from a thin film of polypropylene, enabling it to operate in high-voltage conditions without degradation. The operating voltage for this device is 400V, which makes it suitable for high-voltage applications in both industrial and automotive sectors.

This polypropylene device works on the principle of dielectric polarization. When voltage is applied to this device, the electric charge responds with its own dielectric polarization, allowing for a greater capacitance than conventional electrolytic capacitors. This phenomenon allows this device to store energy and provide a significant level of energy storage when required. Additionally, its ultra-low ESR (equivalent series resistance) greatly reduces the self-heating of the device, enabling it to stay cool even under prolonged high-voltage conditions.

Because of its superior insulation capability and high-voltage performance, the 185153K400RFA-F is well-suited for use in a wide range of electrical applications such as DC power supplies, high-voltage power amps, electric motor drives, and UPS systems. It is commonly used in automotive battery management systems, and providing high-efficiency power for LED lighting systems. The device is also able to handle peak currents, allowing it to store energy for long periods of time, providing a longer life cycle and increased reliability.

This polypropylene film capacitor is also notable for its wide temperature range, being able to withstand operation from -40°C to 125°C without any degradation in performance. This makes it suitable for use in harsh environments, allowing it to be used in outdoor systems that require a high level of reliability and performance.

Overall, the 185153K400RFA-F is a reliable and efficient electric signal processing device. Its superior capability in both high-voltage and harsh-environment applications makes it a great choice for a variety of electric power systems. Its wide temperature range ensures its reliable performance and long lifespan, making it a great addition to any electrical system.
