Film Capacitors

The WMC2D15K-F capacitor is a member of the film capacitor family. As most film capacitors, it is characterized by a high insulation resistance, excellent dielectric properties, a small size, good mechanical robustness, and an easy implementation into all sorts of circuits. The WMC2D15K-F has distinct properties compared to other film capacitors.

Features

The WMC2D15K-F is available in an oval, molded case, and rated for operating voltage of up to 1,400 Volts AC and 2.5 Inches Height. This unique capacitance range and profile make it ideal for a variety of applications, including motor and lighting controls, power factor correction in power supplies, voltage evaluation and other industrial needs. The unique air filled dielectric increases its heat resistance compared to other film capacitors. This makes it a great choice for heavier loads and high current circuits.

Application Field

The WMC2D15K-F is most widely used in motor and lighting control circuits, power factor correction for power supplies, voltage evaluation and other industrial applications that require higher capacitance. It also has the ability to work in high temperature environments, making it suitable for heavier loads and high current circuits.The WMC2D15K-F is generally used in higher-power, square-wave power supplies, providing the ability to store the energy required for switching. It is also frequently used as a line filter for voltage spikes on the mains power. Film capacitors provide much better performance in this regard compared to other industrial capacitors.

Working Principle

A film capacitor consists of two electrodes, usually metal foils, seperated by a thin dielectric film. As an AC voltage is applied, the current flow alternates between positive and negative, creating a continuous cycle of current flow. This results in a storing of energy once all the current flow reaches equilibrium.The electric current generates an electromagnetic field in the dielectric which produces a dielectric displacement effect in the opposite direction to the electric field. As a result, an electric field is generated and stored. When the electric field is removed, the stored charge dissipates and the capacitor reset for the next cycle.The WMC2D15K-F capacitor has a dielectric that is much more heat resistant than other film capacitors, which means that it is able to store more energy and work for longer periods of time without overheating.

Advantages and Disadvantages

The WMC2D15K-F has several advantages including a unique capacitance range and profile, an oval, molded case, and the ability to work in high temperature environments due to its air-filled dielectric. The film capacitor family also offers the most cost effective way to achieve low distortion and low noise levels in audio and video circuits, suitable for whole-house systems and production lines.However, there are some drawbacks as well. Film capacitors are susceptible to moisture and humidity, and may require a specialized coating to protect from corrosion. Furthermore, they are usually less reliable than electrolytic capacitors and should not be used in applications where capacitor failure is not an option. In addition, they also consume more energy than other capacitor types, although their main performance benefit, low distortion, balances out this limitation.
