Film capacitors, also called film dielectric capacitors, plastic film capacitors and film capacitors, are capacitors with a plastic film as the medium between the two electrodes. The most commonly used plastic films are polyester films, polypropylene films, polystyrene films, polycarbonate films and polytetrafluoroethylene films. Film capacitors have featured electrodes which are typically made of aluminum foil and a dielectric layer of film formed by vacuum deposition technique. Film capacitors are not power type capacitors, they are typically low voltage devices with elevated capacitance values.

Among them, ECQ-M2224KZ plastic film capacitor is a type of high precision film capacitor. It has a long life and a stable capacity to voltage ratio. Its main applications include consumer electronics, digital circuits, toys, circuit protection and various other small household appliances. Its characteristics include low equivalent serial inductance, high insulation resistance and wide range of temperature compensation.

ECQ-M2224KZ film capacitors use electrolytic aluminum foil as their electrodes and plastic films as their dielectric layers. The plastic films used are PET, PP, PEN or PPS film, while the polarizing electrolyte consists of a special aluminum oxide layer formed on the film\'s surface by anionic polymerization. ECQ-M2224KZ capacitors have a nominal capacity of 220uf and a rated voltage of 16V.

The working principle of ECQ-M2224KZ film capacitors involves two parts, namely the capacitive element and the ionic charge of the film. The capacitive element consists of two electrodes connected to each other by an insulating medium. When an electric field is applied between the two electrodes by means of an external voltage, a current will flow between them due to the difference in electric potential. This current is known as capacitance current. The capacitance of the capacitor is then determined by the size of the electric field and the amount of electric charge stored between the two electrodes.

On the other hand, the ionic charge of the film is what gives film capacitors their unique properties. The polarity of the charge on the film determines the polarity of the capacitor and this determines the polarity of the voltage applied to the capacitor. It is this charge which allows film capacitors to withstand higher voltages and is responsible for the higher capacitance values compared to other types of capacitors.

The ECQ-M2224KZ film capacitor can therefore be used in a variety of applications. It is most commonly used in consumer electronics and toys, particularly for circuit protection and storing energy within small systems. It can also be used in switching power supplies, rectifiers and DC converters, as well as for signal filtering and signal control in various electronic circuits. Its high insulation resistance ensures a long life and makes it suitable for use in high temperature, high voltage and high frequency circuits.

The ECQ-M2224KZ film capacitor is a reliable and versatile device that can be used in a variety of applications. Its wide range of temperature compensation and long life ensures it will be a great choice for any project requiring high precision, reliable performance and long life.
