Film Capacitors have been frequently used in electrical applications such as radio communications, electronic control modules and even in power systems. A Film Capacitor, such as the MKT1818510066F, can be used as a capacitor, resistor, or both. This capacitor is made from two thin metal foils which have an insulating dielectric material, such as a PVC, between them. The movement of electrons between the foils when a voltage is applied creates an electrical field between the foils which results in a capacitance.

Application Field and Working Principle of the MKT1818510066F

The MKT1818510066F is an AC film capacitor used in applications such as power supply filters, motor start capacitors and AC applications where high across-the-line surge voltages can occur. The film capacitors like the MKT consist of both air gap and dielectric elements.

Air gap elements are the simplest of all capacitors, and consist of two metal plates separated by an air dielectric. When a voltage is applied across the plates, the electric field will want to pass through the air gap, causing a short circuit. When a dielectric material is placed between the two plates, the electric field is effectively blocked, resulting in a capacitor. This is the working principle of the MKT1818510066F film capacitor.

The MKT1818510066F can be used in a wide variety of applications where high levels of AC voltage may occur. It is particularly useful in applications that require low-level impedance and low RF losses. Popular uses include motor start capacitors, power supply filters, and conventional capacitor-start motor applications.

The MKT1818510066F is a general purpose capacitor that provides excellent performance in both AC and DC applications. It is constructed from two thin layers of metal foil separated by a polyester film dielectric. The main benefit of this type of construction is its low ESR (Equivalent Series Resistance) which results in lower losses and higher ripple-current ratings. The low ESR also improves the noise performance of the capacitor.

In addition to its low ESR, the MKT1818510066F film capacitors also provide excellent endurance, withstanding up to 1,000 hours of temperature cycling. This makes them ideal for use in applications that are subject to extreme temperatures and vibration. The capacitors are also RoHS compliant, making them suitable for use in lead-free applications.

The MKT1818510066F film capacitor is a versatile and reliable capacitor suitable for a wide range of AC and DC applications. With its low ESR and excellent endurance, it is an ideal solution for applications requiring high levels of performance and reliability.
