ECQ-E2185KB

Film capacitors have been widely used in different aspects of our life and industry, and they are typically divided into motor run capacitors, power capacitors and various special capacitors upon how they are applied. The ECQ-E2185KB is one of these special capacitors, and it is a kind of axial leaded, snap-in type radial chip capacitor. This article introduces its application field and working principle.

The ECQ-E2185KB uses standard plastic case and epoxy coating for better performance, and is made of self-healing Polyethylene-Naphthalate (PEN) film and fire-retardant plastic. It fits a wide range of applications and is ideal for automotive electronic products, AC adapters, power supplies and other electronic products. It boasts a range of electrical properties such as a maximum operating temperature of 125°C and voltage rating up to 400VAC.

The ECQ-E2185KB adopts the principle of semiconductor capacitance and charge transfer, and its main working principle relies on the formation of an electrostatic shield between two electrodes that store energy, and they can also transfer stored charge. When the capacitor is charged, energy is stored as an electrostatic field between the two electrodes, and when it discharges, it transfers the energy stored as charge. This transfer of energy is regulated by the dielectric of the capacitor, which determines the amount of charge stored and transferred.

Compared to standard electrolytic capacitors, the ECQ-E2185KB has the advantages of low ESR, low impedance, high ripple current and low distortion. Besides, its very long service life ensures long-term use, and makes it suitable for applications where endurance and stability are essential. It also has good stability on temperature variation and vibration, thus need no extra additional measures for compensating its capacitance change.

In conclusion, the ECQ-E2185KB film capacitor is a perfect choice for automotive electronics, AC adapters, power supplies and other electronic products. With its low ESR, low impedance, high ripple current, low distortion and its long service life, it is sure to be a reliable and stable power source in any application.
