The ECW-F2W394JAQ has a dielectric layer of polypropylene film, excellent self-healing properties and a wide operating temperature range. The capacitor has excellent capabilities for handling high inrush currents and surge voltages. The ECW-F2W394JAQ has a maximum working voltage of 500 volts.

The ECW-F2W394JAQ’s application field includes motor drive units, power converters, power electronics, smart grid, and industrial automation. It is also used in applications such as AC and DC motor drives, renewable energy inverters and converters, lighting ballasts, computer power supplies, switching power supplies and surge protection. In these applications, the capacitor provides excellent insulation resistance and can withstand high inrush currents and surge voltages.

The working principle of a film capacitor is based on dielectric constant and electrostatics. The capacitor has two or more layers of dielectric material, with a metal or other electrically conductive material between them. The dielectric material is selected according to its electricity insulating properties, which is known as the “dielectric constant.”

When a voltage is applied across the capacitor’s terminals, the electric field created between the metal layers attracts electrons from one plate to the other, creating an electric charge. This charge builds up until it is equal in magnitude and opposite in sign to the applied voltage and the current flow between the plates stops. The electric field also produces an electric field between the plates, which creates an electrostatic capacitance.

The capacitance of the ECW-F2W394JAQ is high, making it suitable for use in applications with high inrush currents and surge voltages. Its surface mounted form factor makes it easy to install and integrate into a design. The wide operating temperature range and the low impedance, high frequency capability make it an excellent choice for motor drive units, power converters, power electronics, smart grid and industrial automation applications.
