Film Capacitors

Film capacitors—which are also known as AC and DC film capacitors, polyester film capacitors, motor start capacitors and more—are used to store and discharge electricity within electrical and electronic circuits. As with most electrical components, such as transformers and resistors, film capacitors are designed for use in circuit applications where a predictable and dependable electrical performance is required. Furthermore, film capacitors also offer the added benefit of providing a variety of temperature stability and insulation qualities, making them ideal for use in a multitude of industries and applications.

History of Film Capacitors

The very first film capacitors were developed in Germany in the early 1920s. Polyester film capacitors, in particular, have been a popular choice since they made their debut on the market in 1948. Film capacitors began to be widely used in consumer devices such as radios and televisions in the 1950s and, since then, have become an indispensable component in a range of consumer and industrial electronics.

Types of Film Capacitors

Film capacitors are available in two main types: non-inductive and inductive. Non-inductive film capacitors are the most commonly used type, as they are less prone to losing power when being used in high frequency applications. This is due to the fact that non-inductively wound film capacitors contain two layers of conducting material and one layer of insulation, which helps to reduce the amount of power lost when the capacitor is in use. Inductively wound film capacitors, however, contain three layers of conducting material, spaced evenly between two layers of insulation. This type of inductive film capacitor is typically used in applications that demand high voltage characteristics, such as power supplies and power management systems.

MKT1817322014D application field and working principle

The MKT1817322014D is a radial, snap-in style film capacitor with a voltage rating of 100 VAC and a capacitance of 2.2 μF. It offers excellent performance in a wide range of applications, including power supplies, generators, electric motors and more. Its low loss design makes it suitable for high current applications, and its temperature range of -40°C to +105°C makes it a reliable component when used in ambient temperatures.

The MKT1817322014D is a non-inductively wound film capacitor, designed for use in both AC and DC circuits. The two conducting layers are spiral wire wound on a polyester-film dielectric, with each layer separated from the other by an insulation layer. The use of polyester in the construction of the dielectric helps to increase the capacitor’s stability and reduce the risk of performance degradation over time. The capacitor can be used in circuits with voltages up to its rated voltage, however the use of higher voltages may result in decreased performance or even damage to the component.

The MKT1817322014D offers a wide range of benefits, including low self-inductance, low dissipation factor, and high insulation resistance. It is also reliable in operation, making it a preferred choice for many applications. Due to its superior performance and reliability, it is widely used in a number of industries, including automotive, electronics and telecommunications.
