EKY-160ELL222MK25S

Aluminum electrolytic capacitors (AECs) are widely used in modern electronics systems and are ubiquitous components in almost all electrical and electronic systems. The EKY-160ELL222MK25S is one such AEC, marketed as “low-inductance standard capacitors” by its manufacturer. AECs can be described as electrochemical capacitors and provide the highest power densities in comparison to other capacitor families. They are typically used in applications that require large capacitances and/or low equivalent series resistances.

The EKY-160ELL222MK25S is an aluminum electrolytic capacitor of the miniature low inductance variety. It has very low ESR and is extremely small in size compared to other capacitors. It has a voltage rating of 160V DC, a capacitance of 222µF and a tolerance of ±20%. It is capable of operating at temperatures ranging from -40°C to +105°C and has a low temperature coefficient. The EKY-160ELL222MK25S is ideal for use in applications requiring low inductance, high ripple current and minimal ESR such as switching power supplies, audio equipment and advanced motion control systems.

An AEC consists of two aluminum foils separated by a separator membrane and an electrolyte. The aluminum foils form the capacitor’s electrodes, while the separator and electrolyte form the capacitor’s dielectric. The polarization of the AEC’s electrodes occurs when the capacitor is connected to an external voltage source. This is known as an electrolytic reaction and is the result of an unpolarized current flowing through the electrodes and electrolyte. The polarization of the capacitor’s electrodes causes them to become oppositely charged and an electric field is created between them. The electric field is responsible for storing electrical energy, thus forming the basis of an AEC’s working principle.

The EKY-160ELL222MK25S is constructed of two aluminum foils and a separator membrane that are immersed in an electrolyte solution. Its capacitance is determined by the size of the aluminum foils, the area of overlap and the thickness of the separator membrane. Its ESR is determined by the resistivity of the electrolyte, the thickness and composition of the separator membrane and the internal resistance of the aluminum foils themselves.

In summary, the EKY-160ELL222MK25S is an aluminum electrolytic capacitor of the miniature low inductance variety. It is capable of providing a high capacitance relative to its size, excellent temperature resistance and low ESR. As such, it is ideal for use in applications that require low inductance and high ripple current such as switching power supplies, audio equipment and advanced motion control systems.
