Film capacitors, also known as Polymer capacitors, are high-performance capacitors. Commonly used models are ECW-FA2J125J. This is a small size product with a maximum rated voltage of 250VDC, which is widely used in the industry. This article will introduce the characteristics, application field and working principle of ECW-FA2J125J.

Characteristics

First of all, ECW-FA2J125J\'s dielectric is Polypropylene Film, which is low the dielectric losses and high insulation resistance. ECW-FA2J125J is able to hold large voltage, high breakdown voltage and good insulation characteristics. Its temperature coefficient is also quite low. The moisture absorption of ECW-FA2J125J is also small, so it has excellent stability and long service life. This product has wide voltage scope and its capacitance range is 0.0082uF-0.047uF, it is an extremely low-loss capacitor which is formed by coating first-class plastic films and winding into a cylinder.

Application Field

ECW-FA2J125J is one of the most widely used film capacitors. This film capacitor has strong resistance to temperature, voltage and frequency. And it is widely used in the fields of medical equipment, communications, electric power, military, power electronics, electric instrumentation and audio. It can cooperate with other devices and components to complete many amazing applications, such as electric cars, robots, electronic equipment, electric vehicles, motor control, electronic energy storage, mobile phone power management.

Working Principle

The capacitor consists of a dielectric and two plates insulated by the dielectric. The two plates are made of a conductive material, while the dielectric is an insulator. When the two plates have a certain potential difference, the force of electric field appears and one charge is stored on each plate. The process of storing energy is energy storage, so the capacitor can store energy.

The ECW-FA2J125J uses the dielectric of Polypropylene Film to achieve higher capacity than electrolytic capacitors. Dielectric has a large effect on capacitance, so the capacitance decrease as the temperature increases. ECW-FA2J125J has the advantage of good temperature coefficient, it has been able to keep the dielectric constant under a certain temperature.

ECW-FA2J125J does not generate heat during working, and it does not need liquid cooling as electrolytic capacitors do. This ensures the reliability of ECW-FA2J125J. Moreover, the precision of capacitance of ECW-FA2J125J is relatively high. The total errors of the product are less than 5%, the measurement results are more accurate.

ECW-FA2J125J has many advantages and its application fields are very broad. It is a high-performance capacitor with excellent characteristics and performance. It has become a popular choice for many application fields.
