Film capacitors, also known as film dielectric capacitors, are 3-terminal capacitors with a film as the dielectric. The most common type of film capacitors is the polyester type, which is the most commonly used electrolytic capacitor in AC applications. These are used in a wide range of electronic equipment, from high-frequency audio equipment to acousto-optic modulators.

The ECQ-E6564JFB film capacitor is an excellent choice for AC applications such as switch mode power supplies, AC motor drives, and other applications. The ECQ-E6564JFB is a 3-terminal capacitor with a maximum voltage rating of 600 volts, a maximum ripple current of 100mA, and a maximum leakage current of 5mA. Its dielectric is an ethylene tetrafluoroethylene-based film with a temperature coefficient of approximately -33ppm/C.

The main application field of the ECQ-E6564JFB is in switch mode power supplies. The capacitor provides energy storage to compensate for intermittent current demands from the load, while protecting against power line disturbances. It also serves as a filter, reducing the peak voltage and increasing the power factor. The capacitance value and size necessary will depend on the required load current and the allowable output voltage ripple.

The working principle of the ECQ-E6564JFB is based on the charge-discharge cycle of a capacitor. A series circuit with the ECQ-E6564JFB and a resistor is used, with the capacitor initially charged to the required voltage. When the switch is closed, the capacitor starts to discharge through the resistor, producing a decaying voltage and an associated current flow. When the voltage has decayed to zero, the switch is opened, and the capacitor starts to charge again through the resistor. This cycle is repeated, and the capacitor voltage is monitored by the controller. This process is repeated until the desired voltage is reached.

The ECQ-E6564JFB film capacitor is a highly reliable product with superior features such as low leakage current, low equivalent series resistance (ESR), and a quick response time. It is designed to operate in high temperature and high humidity conditions, and is RoHS-compliant. The ECQ-E6564JFB is a great choice for AC applications such as switch mode power supplies, AC motor drives, and other applications where reliable and efficient performance is required.
