Film capacitors, also known as plastic film capacitors, are increasingly popular due to their superior performance and low cost. WMC2D47K-F is a type of film capacitor widely used in industrial and automotive applications. It is constructed from two sheets of polypropylene film that are sandwiched between two aluminum electrodes for increased reliability and performance. The capacitor is encapsulated in an epoxy coating to protect it from the elements and ensure long-term performance. The WMC2D47K-F has a rated voltage of up to 450V AC and a temperature rating of -40°C to 85°C.

The WMC2D47K-F capacitor is commonly used in power electronics system, such as switch mode power supplies (SMPS), adjustable speed drives, UPS systems, motor drives, and automatic speed control units. It is a self-healing type of film capacitor, which means that the capacitor can recover from damage due to excessive current or stress. The capacitance of the WMC2D47K-F ranges from 0.015uF to 2.2uF, with a dielectric strength of 1.5kV AC and an insulation resistance of 5,000 MΩ. The capacitor also has low dissipation factor and low temperature dependence, making it suitable for applications requiring high capacitance stability under varying temperatures.

The WMC2D47K-F capacitor’s working principle is fairly simple. When a voltage is applied across the capacitor, an electric field is created between the two conductive metal plates. This electric field causes the plates to be attracted towards each other and the space between them is filled with an insulating dielectric, such as polypropylene film. When an alternating current is applied to the plates and the dielectric material, the alternating field causes a small amount of current to be created and stored in the capacitor. This stored energy is then used to power various electrical components or systems.

The WMC2D47K-F is a reliable and cost effective capacitor that can be used in a variety of applications. Its superior performance and long-term stability make it an ideal choice for power electronic systems, such as motors, lighting systems, and HVAC, among many others. Additionally, the WMC2D47K-F is suitable for harsh environments, including those with high temperatures or humidity, owing to its robust epoxy coating.
