Film Capacitors

Capacitors are electronic components commonly used to store and release electricity. They store electric energy in both the forms of static electric charges and electric voltage. One of them is the film capacitor, is made of thin plastic films such as polyester (PET), polypropylene (PP), polystyrene (PS), Teflon (PTFE), etc. Film capacitors have the advantage of low inductance, high dielectric strength, excellent temperature stability, high reliability and long life expectancy. Their electrical parameters are almost independent of frequency.

ECW-F2105JAB Application Field and Working Principle

ECW-F2105JAB is a special type of film capacitor offered by Shenzhen JPW Technology Co.,Ltd. It is used for various applications in the field of Electrical, Electronics, Automobile, Medical, Lighting, and Energy Management. It is generally used for filtering, coupling, and bypass circuits. The capacitors also have high temperature and humidity resistance.

The functioning of the ECW-F2105JAB film capacitor is based on the principle of capacitance. It works by storing electric energy in the form of static electric charges and electric voltage between two conducting surfaces separated by a dielectric material. The two conducting surfaces are usually made up of aluminum foil and are separated by a single layer or multiple layers of polyester film. When electric current passes on the electrodes, electrons are accumulated and stored on the conducting surface resulting in the formation of electric potentials. When the potentials reach a certain level, the capacitor is charged and the electric current is blocked. This complete process of storage and blocking electric current forms a capacitor circuit.

The ECW-F2105JAB has a high energy storage capacity and its temperature and humidity resistance is superior to other types of film capacitors. It has a low ESR value (Equivalent Series Resistance) and a low tolerance range, making it more stable in performance. It is particularly suitable for applications like voltage filtering, high frequency signal bypass application, DC-DC conversion input or output buffer, forming a compensation COG network to reduce EMI (Electromagnetic Interference), etc.

The ECW-F2105JAB is also used for the anti-interference purpose on data communication and video and audio equipment. It has a wide range of operating voltage and temperature range. It is suitable for high voltage slow charging/discharging circuit as well as crash switching operations, can operate in a wide frequency range and has a high grade dielectric breakdown. It is an ideal choice for applications involving capacitive load, for noise filtering, signal buffering and power supply converting.

The ECW-F2105JAB is widely used in automotive, medical, lighting and energy management systems. It is suitable for applications such as passenger vehicle electronics, AC alternator and inverter, switching circuit, audio amplifier etc. Its rugged construction allows it to be used in harsh environmental conditions. It is also used in solar cell connection systems and medical imaging equipment, as well as in LED driver systems.

The ECW-F2105JAB can be used in many other applications as well. It is suitable for AC switching operation, for use in power supply converters and for anti-interference purpose on data communication and video & audio equipment. Its excellent electrical characteristics include low ESR, low temperature drift, and low impedance, making them a great choice for many applications.
