Film capacitors are constructed using metallized film as the dielectric material. They are some of the most reliable and stable capacitors available, as they have very low rates of dielectric absorption and losses, meaning that the dielectric material retains its original insulating properties, such as its ability to prevent leakage of current over time. These capacitors are also not affected by humidity and temperature changes and can handle high frequencies, up to 1GHz.

ECQ-E2393KBB belongs to this category of film capacitors. It is a self-healing polypropylene film capacitor, which has a polypropylene (PP) layer as the dielectric. It is designed for 105 degree Celsius operating temperature and uses silver and zinc wires as electrodes. This capacitor is wrapped in a metallized polypropylene film, which makes it highly resistant to insulation failure. The PP film ensures that the capacitor has minimal polarization and time-based variation in electrical characteristics.

This capacitor has wide applications and is used in many different fields. The most common applications are in power electronics such as in DC link capacitors for inverters and low voltage motor drive systems; in communication systems such as for broadcast and telecom equipment; in automotive systems; and in audio equipment and industrial controllers. Aside from these, ECQ-E2393KBB is also widely used in markets such as renewable energy and medical equipment.

The working principle behind the ECQ-E2393KBB capacitor is electrostatic induction. This occurs when two conductors, such as the silver and zinc wires on the capacitor, are separated by a dielectric, such as the PP film on the capacitor. Whenever a voltage is applied across the conductors, a static electric field is formed, which induces a current in the direction of the electric field. This produces an opposing electric field, which in turn induces another current, resulting in a continuous flow of current in the capacitor. This is what is known as the electric current, or capacitance.

The ECQ-E2393KBB film capacitor is a reliable and stable capacitor with a wide range of applications. Its self-healing PP film and silver/zinc electrode design make it highly resistant to insulation failure. This makes it a great choice for many power, audio, and communication applications, as it is able to handle high frequencies, withstand temperature and humidity changes, and maintain its insulating properties for a long time.
