Working Principle of the ECW-FD2W474P1

The ECW-FD2W474P1 is an electrolytic-film capacitor that works on electrostatic principles. The metallized polyester film is coated with a conductive material and then rolled onto a spool. This forms multiple layers of film, which are then connected to the two electrodes. When a voltage is applied across the film, an electric field is created, which causes a charge separation. The charge separation creates a property known as capacitance, which is measured in Farads. The more layers of film, the higher the capacitance.

Capacitance is an important parameter to measure when selecting the right capacitor for a particular application. The ECW-FD2W474P1 has a maximum capacitance of 0.47µF and a tolerance of ±10%. This indicates that the capacitance of the capacitor can vary by ±10%, allowing for a wide range of uses.

In addition to the capacitance, the ECW-FD2W474P1 also has a maximum voltage rating of 650V and a temperature coefficient of -55°C to +105°C. These parameters must be taken into account when selecting the right capacitor for a particular application. The maximum voltage rating indicates the maximum voltage the capacitor can withstand, while the temperature coefficient indicates how much the capacitance of the capacitor changes with changes in temperature.

Overall, the ECW-FD2W474P1 is a reliable film capacitor that is used in a wide variety of applications. Its wide operating temperature range and high maximum voltage rating make it suitable for use in a variety of different environments, from power factor correction to high voltage inverters. Its wide capacitance range and tolerance also make it suitable for many different applications.
