Introduction

Film capacitors, also known as plastic film capacitors or polymer film capacitors, are energy storage components that are widely used in modern electronic devices. They are made with capacitive films which are manufactured from a variety of materials such as plastic films, ceramic layers, foams, and other dielectric materials. ECQ-B1271JF is a type of film capacitor feature with high capacitance and excellent temperature stability. It is mostly used in high power radio frequency applications, such as switching power supply, inverter, etc. This paper will explain the application field and working principle of ECQ-B1271JF.

Application Fields

ECQ-B1271JF are widely used in high power and high frequency radio applications, such as inverters, switching power supply, and other RF communication systems. It is also suitable for circuit with high precision such as audio circuits and computer peripherals, and high quality power line filter circuits. In addition, ECQ-B1271JF are also used in large motor control, LED lighting, etc.

Working Principle

ECQ-B1271JF is a kind of film capacitors that utilizes the dielectric film and metallic electrodes to create a capacitor element and stored electrical energy. The basic structure of ECQ-B1271JF consists of two metallic electrodes and dielectric film between them. The dielectric film acts as an insulating medium and the electrodes act as current conductor. When a charge is applied to the electrodes, the film capacitor will store the charge and hold an electrostatic potential between them. This electrostatic potential will be discharged when the charge is depleted and the capacitor will recharge to its original condition.
