Its design also allows for a wide range of working temperature ranges, from -55°C to 85°C, making it suitable for use in a variety of environments.

Working Principle

The ECQ-E1473KF is a metallized film capacitor made of metalized polyester film. This type of capacitor is constructed by electrically connecting two pieces of metalized film using an electrically conductive material. The metalized film is then wrapped around an insulator, such as a polypropylene, or aluminum oxide dielectric. The insulator is then immersed in an electrically conductive fluid, such as a liquid electrolyte, or oil.When a voltage is applied to the ECQ-E1473KF, the metalized film acts as an electrical conductor. It stores energy in the form of an electrostatic field between the two pieces of metalized film. This stored energy produces an electric force which can be used to power electrical appliances or circuits.In addition, the ECQ-E1473KF also has a small ESR (Equivalent Series Resistance), which can be beneficial in AC filter circuits. The ESR helps the capacitor to absorb ripple currents and also helps to reduce the amount of waste heat produced by the capacitor as well.
