Film capacitors are electrical components that are made up of multiple layers of insulation material, typically plastic or paper. They are widely used in the fields of electronics and electrical engineering, as they are well-suited to handle large currents and are able to block fluctuations in voltage. The C4AF9BW5170A3OK is a type of film capacitor made from polypropylene dielectric and aluminum foil. It is most commonly used for applications such as pulse discharge, power supplies, resonance circuits, and motor starters.

Applications

The C4AF9BW5170A3OK is best suited for applications that require stable performance and high frequency response. Its high current capacity makes it a popular choice for power supply smoothing and filtering, as well as for pulse discharge circuits where fast switching is required. The C4AF9BW5170A3OK is also used in motor starters and resonance circuits, due to its high- and low-frequency response ratings.

Working Principle

The C4AF9BW5170A3OK works on the same principle as other film capacitors. When a voltage is applied across the capacitor, it effectively stores the electrical energy by creating an electric field between the two layers of insulation material. This is known as the dielectric effect. The electric field builds up in proportion to the applied voltage, creating an opposing electrical force that can be used to charge the capacitor and store electrical energy.

The C4AF9BW5170A3OK’s polypropylene dielectric material provides excellent high-temperature and flame-resistant properties, making it ideal for use in high-temperature environments such as motors and power supplies. The aluminum foil used in the construction of the C4AF9BW5170A3OK offers great electrical insulation and a low leakage current, making it very reliable in applications where pulse discharge is important.

The C4AF9BW5170A3OK is rated for an operating voltage of up to 85V DC (direct current) and a surge voltage of up to 200V DC. Its temperature range can go from -25°C to +85°C. Additionally, it has a capacity of 0.2μF, a dissipation factor of 0.50, and a self-healing property, making it resistant to dielectric breakdown and allowing for a longer lifetime than other types of capacitors.

The C4AF9BW5170A3OK is a high-performance film capacitor that is suitable for a variety of applications, including pulse discharge, power supplies, resonance circuits, and motor starters. Its high current capacity, temperature and voltage ratings, and self-healing properties make it a reliable and versatile choice for many electronics and electrical engineering applications.
