Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are the most widely used type of capacitor in electrical engineering. They are composed of two aluminum foils (typically an anode and a cathode) separated by a dielectric separator of either paper or a plastic material, which is soaked in an electrolyte. This dielectric holds a certain amount of electrical charge and acts as a barrier to prevent the flow of current between the two metal plates. The level of electrical charge that can be stored in a capacitor is related to its voltage rating, and the amount of current it can handle is related to its capacitance.

EKZN6R3ELL122MH15D Application Field and Working Principle

EKZN6R3ELL122MH15D capacitors are aluminum electrolytic capacitors with a capacitance of 1.2 μF, rated voltages of 10, 16, 25 and 50 VDC, and a capacitance tolerance of ±8%. The application field for this part is in general motor drive and power supply systems, with a max ripple current of 4.3A and temperature range between -40°C to +105°C.

The working principle of EKZN6R3ELL122MH15D capacitors is based on the principles of capacitance, in that they convert electric energy into stored charge. The capacitor works by transferring electric charge between its two different plates, with the amount of charge stored depending on the voltage applied across the capacitors electrodes, and the current rating determined by the capacitance.

When voltage is applied to the capacitor, electric charge is stored on the metal plates, and when the voltage is removed, the charge dissipates. The amount of charge that can be stored is related to the size of the capacitor and the voltage applied, and this determines the level of peak current that is allowed to pass through the capacitor before it releases the stored charge.

The capacitor also acts as a filter, allowing some frequencies of current to pass through and blocking others. This is a result of the capacitance value, the higher the capacitance the lower the frequencies that will be blocked, and vice versa. Thus capacitors can be used to tailor the currents that enter a certain circuit, allowing only the desired frequencies to pass through.

Aluminum electrolytic capacitors are typically used in electric motor drive and power supply circuits to store charge and preserve the frequency response of the circuit, providing stable voltage, current, and power levels.

In summary, EKZN6R3ELL122MH15D is a type of aluminum electrolytic capacitor with a capacitance of 1.2 μF, and DC voltage ratings of 10, 16, 25, and 50 VDC. Its applications include general motor drive and power supply systems, where its capacitance, voltage and ripple current ratings make it ideal for these purposes.
