Introduction

Film capacitors are a type of capacitors that are constructed using capacitance film. The capacitance film is typically formed with layers of plastic material if it is a non-polarized film capacitor, and one layer of plastic and one metallic layer if it is a polarized film capacitor. Film capacitors have a much higher energy and no charge handling capacity as compared to other type of traditional capacitors. They are also more reliable and have a lower drainage rate and self-healing ability. This makes them ideal for use in power applications.

394MKP275KE application field and working principle

The 394MKP275KE is a 275VAC rated, 2000VAC breakdown voltage film capacitor, mainly used in industrial applications. The capacitor is certified UL, CSA, and VDE. This makes it suitable for a wide range of applications that involve harsh and polluted environments where the capacitor is exposed to temperatures ranging from -40C to +105C.

The 394MKP275KE uses a polypropylene film as the main dielectric, made from high quality polypropylene film and a decoupling element, which allows for good stability and reliability. The main dielectric is also designed to avoid micro-crystalline, which improves the dielectric’s lifetime. The capacitor’s outside case is made from PPE and has a stable construction and is easy to install. The PPE material is rated IP00, air tight and waterproof, which increases the capacitor’s life span and reliability.

The 394MKP275KE has a very simple working principle. The capacitor consists of two electrical plates that are separated by an insulating material called the dielectric. The electric field strength produced between the two plates depends on the electric charge that passes through the plates and the material’s dielectric constant, which determines the amount of electrical energy stored in the capacitor.

The 394MKP275KE gives a wide range of voltage and frequency ranges, up to 275 VAC and 800 Hz respectively, which makes it a very versatile product. Additionally, it offers outstanding insulation performance to ensure product reliability, with excellent performance after overvoltage and power factor tests.

Conclusion

The 394MKP275KE film capacitor is a very reliable component for a wide range of applications and offers a wide range of voltage and frequency ranges. It has a simple working principle and is designed to have a high insulation performance to ensure reliability. The product also features a robust construction and is certified UL, CSA, and VDE making it an ideal component for industrial applications.
