ECQ-E4225KFW

Film capacitors, also known as dielectric thin-film capacitors, are passive two-terminal electrical components used to store electrical energy in an electric field. They are made by depositing a thin film of plastic or ceramic material between two conducting electrodes. Film capacitors are mainly used in power conditioning, filtering and regulation circuits, as well as audio and instrumentation applications. The ECQ-E4225KFW is a unique type of film capacitor designed for high frequency switching and power factor correction.

The ECQ-E4225KFW is an ultra-compact, low-profile capacitor with a self-healing polyester film dielectric, thinner than conventional film capacitors of a similar size. The voltage rating of the ECQ-E4225KFW is 250 VAC, and is available in capacitance values from 0.47 microfarads (µF) to 1.2 microfarads (µF). It is mainly used in LED lighting, home appliances, air-conditioners, power supplies, and solar energy systems.

The ECQ-E4225KFW offers maximum operating frequency of 250 kHz and has a Ripple Current (RMS) rating of 0.24A. The main advantage of this capacitor is that it has high inrush and current handling capabilities, which makes it suitable for switching and power factor correction applications. Additionally, its thin form factor and low profile allows for use in high-density circuit boards.

In terms of working principle, the ECQ-E4225KFW is essentially a device that stores energy as an electrical field between two electrodes when voltage is applied across it. When the voltage is removed, the energy stored in the electrical field is released. The energy is then dissipated as heat and eventually converted into an electrical current.

The ECQ-E4225KFW is also capable of self-healing, which means that it can repair itself after sustaining any kind of damage due to over-voltage or extreme temperatures. The self-healing process is initiated by burning away the damaged portion of the dielectric film, which eliminates the short-circuit caused by the damage. The ECQ-E4225KFW is ideal for applications where reliable operation and sustained energy storage is required.

Overall, the ECQ-E4225KFW is a unique type of film capacitor designed for high frequency switching and power factor correction applications. It offers the advantages of a low profile form factor, high inrush and current handling capabilities, and self-healing capability. As a result, it is ideal for applications such as LED lighting, home appliances, air-conditioners, power supplies, and solar energy systems.
