Aluminum electrolytic capacitors are one of the most widely used and cost effective forms of capacitors available on the market, delivering relatively high capacitance per unit volume and are used in a variety of applications. The ECE-A1CKS100I belongs to the family of Aluminum electrolytic capacitors, and is often used in both high frequency and low frequency applications. In this article, we will explore its application field, as well as its working principle.

The ECE-A1CKS100I is an axial-type aluminum electrolytic capacitor that offers improved properties over general purpose aluminum electrolytic capacitors. It is widely used in a variety of applications due to its wide capacitance range ranging from 2.2uF to 220uF and a high voltage rating of up to 35V. It is ideal for DC-to-DC converter, rectifier circuit and switching power supply, noise suppression and filtering, snubber circuits or capacitor-input filters. Furthermore, this component is ideal for providing high ripple and low ESR (Equivalent Series Resistance), meaning that it is well suited for applications that require long life and a low failure rate.

Generally speaking, aluminum electrolytic capacitors are polarized devices which means they can only be inserted in one direction. Based on the component frame, the negative terminal of an aluminum electrolytic capacitor is usually marked with a black stripe. This component can be connected as electrolytic capacitors in series and/or parallel. In addition to that, it is important to keep the DC ripple current within the rated current of the component.

The ECE-A1CKS100I aluminum electrolytic capacitor works according to the principle of Faraday\'s laws of electrolysis. It consists of a rolled anode, made of aluminum foil and an electrolyte (most commonly an aqueous solution or organic solvent) together in a non-conductive injection-molded container. The aluminum foil is then anodized, i.e. plated with a thin layer of oxide, so that the aluminum foil does not directly contact the electrolyte. As a result, two layers of media are generated in the aluminum electrolytic capacitor: a dielectric oxide layer (also known as the dielectric layer) and the two metal layers.

When voltage is applied to the aluminum electrolytic capacitor, electrons will move from the anode to the cathode and create a field. This field increases the electric potential of the anode and attracts positively charged ions from the electrolyte. The electrolyte ions become split, with the cations (positive ions) attracted to the anode, and the anions (negative ions) attracted to the cathode. As the cations are attracted to the anode, they react with the anode, forming a thin film of oxide (the dielectric). As a result, charge accumulates on the anode and creates a capacitance. This appears across the two electrodes of the aluminum electrolytic capacitor and the capacitance is proportional to the size of the anode and the oxide layer.

In conclusion, the ECE-A1CKS100I is an axial-type aluminum electrolytic capacitor which offers a wide capacitance range and a high voltage rating. It is well suited for a variety of applications including DC-to-DC converters, rectifiers, noise suppression and filtering, and snubber circuits. The capacitor works according to Faraday’s laws of electrolysis and works when electrons move from the anode to the cathode and create a field, resulting in the accumulation of charge on the anode which results in the formation of the dielectric layer and the capacitance appears across the two electrodes.
