MKT1817468066

Film capacitors, also known as metalized film capacitors, are passive electrical components which store energy in an electric field between two conductors, usually referred to as the plates of the capacitor. These capacitors are used in an array of applications including power factor correction, noise filtering, decoupling, and energy storage. The MKT1817468066 is one such capacitor, with specific characteristics that are beneficial depending on the application.

MKT1817468066 Applications

The MKT1817468066 capacitor is a radial leaded, metallized polypropylene film capacitor. Specifically, it has a capacitance of 18uF and a voltage rating of 250VAC. This particular capacitor is ideal for use in AC motor start and run applications, as well as in filters such as mains filters, capacitor banks, and snubbers. The active life of the MKT1817468066 capacitor is 2000 hours, however, its lifetime is rated at 6000 hours.

MKT1817468066 Working Principle

The working principle of a film capacitor is based on the electrostatic principle of storing energy between two conductors. As the voltage across the plates increases, the electric field, or electrostatic field, between the plates increases. This electrostatic field stores the electrical energy, and as such, the capacitor, or energy storage unit, becomes charged. The application of an electric current across the plates of the capacitor causes electrons to accumulate on one plate and deplete from the other, thus creating the charged condition.

The MKT1817468066 capacitor mainly finds use in power factor correction applications, where it is used to reduce the effect of fluctuations in the power supply and maintain the power factor at a constant level. This helps make the power supplies more efficient and lowers the costs associated with power generation and transmission.
