Film capacitors belong to a family of capacitors that are characterized by their use of dielectric films. Common types of film capacitors include polyester, polyethylene naphthalate (PEN), polypropylene, and polystyrene. These films are ubiquitous in electrical and electronic equipment, as they offer several advantages over traditional capacitors. They are lightweight, have a stable temperature coefficient of capacitance, are mechanically robust and have low losses.

The WMF05W1K-F, developed by ZCAP, is a polyester film capacitor designed for high-voltage, high-frequency applications. This film capacitor has a rated voltage of 500V AC and an operating temperature range of -40°C to +85°C. It has a high insulation resistance and excellent AC voltage performance, making it suitable for use in high-voltage power supplies. Its capacitance value is 5mF.

The WMF05W1K-F’s construction features a metallized film that is tubular in shape with two end wires. The capacitor is wound into a tubular shape using a polyester dielectric film surrounded by a flexible metal foil. Its electrodes are tinned copper wire. Its body is made of epoxy resin and has a radial leaded design with good electrical performances. Additionally, the capacitor is rated for 105°C of temperature.

The WMF05W1K-F capacitor is well-suited for use in applications that require low-inductance performance. Its low ESR and ESL values make it suitable for high-frequency switching power supplies, UPS systems, and other power electronics applications. Its high rated voltage rating makes it an ideal choice for high-voltage AC circuits. It is also capable of withstanding high transients with minimal heat generation, allowing it to be used in demanding electrical circuits.

The WMF05W1K-F works by storing energy as an electrostatic field in the dielectric material between the two electrodes. In a DC circuit, current flows through the capacitor in one direction, charging the dielectric material. In an AC circuit, current alternates between forward and reverse direction, leading to a charge-discharge cycle. The capacitor is able to store energy by storing its charge and then releasing it as the AC voltage reaches its maximum and minimum values. This results in a reduction of the AC voltage, leading to a less noisy signal and improved system performance.

The WMF05W1K-F polyester film capacitor is a reliable and durable product that is well-suited for use in a wide range of high-voltage, high-frequency applications. It has a robust construction and long-term stability, making it capable of delivering improved performance for years. Its ability to withstand high transients and its low inductance values give it the flexibility to be used in a wide range of power electronics applications.
