MEXY2A183K Film Capacitors

Film capacitors, also known as polyester film capacitors, are a type of high-value capacitors used in consumer and industrial applications for several years due to their excellent characteristics. The MEXY2A183K is a film capacitor designed and manufactured by Cornell Dubilier specifically for high-temperature, high-voltage applications.

Features

The MEXY2A183K features a capacitance value of 1.8 nF and a maximum voltage of 10 kV. It is rated for temperatures up to +200°C and offered in a variety of case sizes ranging from 2, 3, and 5 inches. It has a capacitance tolerance of ±10% and a dielectric strength of 250 V/mil (min). The MEXY2A183K is also RoHS compliant and UL Recognized under the UL 810 standard.

Applications

The MEXY2A183K is most commonly used in industrial, automation, electrostatic air filters, energy-storage, high-voltage, frequency-control, and resonance applications. It is specifically designed for extreme temperature environments and is well-suited for use in systems with alternating current (AC) loads or high voltage DC loads.

Working Principle

The principle of a film capacitor is relatively simple. It consists of two metal plates that are mounted in parallel and separated by a thin sheet of dielectric material. When voltage is applied to the capacitor, the lossless dielectric material holds the charge on the plates until it is discharged or dissipated. This subsequently allows the capacitor to store electrical energy and release it when necessary. The key features of film capacitors make them suitable for many different applications. They offer high breakdown voltages, low losses, long life, and high operating temperatures. Additionally, they have good frequency characteristics, meaning they are DC-stable, have a low capacitance-voltage coefficient, and offer low impedance and resonant frequencies.When it comes to safety, film capacitors have some advantages over other types of capacitors. They are self-healing, meaning any dielectric breakdown that takes place will dissipate the voltage across the plates before it reaches a dangerous level, resulting in minimal threat to personnel or equipment. Overall, the MEXY2A183K is an excellent film capacitor for industrial, automation, energy-storage, and high-voltage applications. Its high temperature and voltage ratings make it well-suited for extreme environments, and its self-healing properties make it a safe, reliable solution.
