The rated ripple current is 200mArms and the peak current is 22A. Additionally, it has an insulation resistance of 500M Ohm at 500V DC.

Working Principle

The ECQ-E4474JF3 is a film capacitor, which means it works by using a thin sheet of a dielectric material like polyester or polypropylene. Film capacitors are very reliable and efficient as they can store and release energy quickly. Essentially, a film capacitor works by having two conductors separated by a dielectric material. When a voltage is applied to the two conductors, a small electric field is created within the dielectric material. This electric field creates charges on the surface of the material which in turn creates a capacitance.

Applications

The ECQ-E4474JF3 is suitable for a variety of applications, including, static electricity suppression, line filtering, inverters, energy storage, power Supplies, and high dynamic range signal circuits. It can also be used in various electromagnetic interference suppression circuits, as well as various other circuits such as rectifiers, voltage regulators, and motor starters. Its robust design and high temperature tolerance also make it well suited for very harsh environmental conditions. All these features make the ECQ-E4474JF3 an ideal choice for many power applications.
