E91F421VND122MBA0T

Aluminium electrolytic capacitors are components consisting of two aluminium foils separated by a thin layer of oxide. They provide a large capacitance per unit volume, making them extremely useful in power electronics designs. This article outlines the application field and working principle of the E91F421VND122MBA0T aluminium electrolytic capacitor.

The E91F421VND122MBA0T aluminium electrolytic capacitor is a radial, non-polarized capacitor with a capacitance of 4.7µF. It is rated up to 420V and has an operating temperature range of -25°C to +105°C.

The application fields of the E91F421VND122MBA0T capacitor are many because of its high voltage and temperature ratings. It is commonly used in high-power electronic equipment such as automotive, motor control, lighting, telecom, power supplies and UPS systems. The capacitor is suitable for both DC and AC circuits.

In terms of its working principle, the E91F421VND122MBA0T capacitor relies on two plates with opposing charges. One side of the capacitor is connected to a positive voltage source, while the other is connected to ground. This creates an electrostatic field between the two plates that stores energy. When the voltage across the capacitor changes, electric charges are transferred between the plates, thus changing the capacitor’s electrical state.

The E91F421VND122MBA0T aluminium electrolytic capacitor is a reliable and cost-effective high-voltage capacitor. Its high capacitance and voltage ratings make it suitable for a wide range of applications, and its robust construction makes it an excellent choice for long-term use.
