ECQ-E6122KF

Film capacitors, also known as plastic film capacitors, are capacitor components with a dielectric formed by a plastic film with a thickness ranging from a few micrometers to several hundred micrometers. Due to their superior performance, such as high temperature stability, high volumetric efficiency, small size, low leakage current, and excellent self-healing properties, film capacitors are widely used in modern electronic products. In this article, we will introduce the application field and working principle of ECQ-E6122KF, a popular film capacitor. The ECQ-E6122KF is a cylindrical plastic film capacitor. It is made of capacitor plastic film and a thin aluminum foil as the core layer and electrodes, with a dielectric formed by metallized polypropylene. It is mainly used in pulse circuits and switching power supply to suppress high frequency noise and reduce power factor. In high-precision electronics, ECQ-E6122KF is also used as a filter, energy storage, and alternating current filter. Similar to other capacitors, the ECQ-E6122KF works on an electro-static principle. When a voltage is applied to two conductive electrodes, a charge will accumulate on the electrodes and an electric field will be formed between them. This electric field will then transmit the electrical energy from one electrode to the other in the form of an electric current. The ECQ-E6122KF is designed to store electrical energy in the electric field and to dissipate it when the voltage across the electrodes drops, thus preventing the flow of current.There are three important parameters for determining the performance of the ECQ-E6122KF: capacitance, voltage rating and impedance. The capacitance of the ECQ-E6122KF indicates the amount of charge it can store, which is measured in Farads. The voltage rating of the ECQ-E6122KF refers to the maximum voltage that the capacitor can tolerate, while the impedance of the ECQ-E6122KF is an indication of the current that can be passed through the capacitor. The higher the impedance, the lower the current that can be passed.In addition, the ECQ-E6122KF has some unique properties that make it a preferred choice for many applications. It is highly resistant to temperature and humidity and can withstand extreme temperatures up to 125℃. It also features low ESR (equivalent series resistance) that ensures stable performance over long periods of time. The aluminum core is also capable of self-healing and has superior electrical arc-erosion characteristics.In summary, the ECQ-E6122KF is a great choice for low-power applications that require reliable performance over long periods of time. Its unique properties and design make it ideal for use in pulse circuits, power supplies, and high-precision electronics. With its low ESR and excellent temperature and humidity resistance, the ECQ-E6122KF is a great option for applications where reliability is a key factor.
