EKYB350ELL182MK30S

Aluminum Electrolytic Capacitors are a type of capacitor which utilizes an electrolyte to achieve a larger capacitance than other types of capacitors. These capacitors are formed by two layers of aluminum foil, a dielectric material (such as paper or plastic), and an electrolyte, which is normally liquid,. EKYB350ELL182MK30S is one type of aluminum electrolytic capacitor, widely used in various fields. Below we will discuss its application fields and its working principle.

Application Fields

The EKYB350ELL182MK30S aluminum electrolytic capacitor is a high-performance model, relatively light in weight, with small internal power loss and high electrical stability, good recovery performance, and wide range of operating temperature from -55 to +105℃. These characteristics make EKYB350ELL182MK30S aluminum electrolytic capacitor suitable for filter-circuits and energy storage such as DC&AC filter, adjustable and stabilizing circuits, DC&AC bypass, etc., as well as in audio-frequency filters and other related electronic equipments application.

Working Principle

As mentioned above, EKYB350ELL182MK30S is a type of aluminum electrolytic capacitor. This type of capacitor has two sides of aluminum foil which are covered with a dielectric material. In between the two aluminum foils lies an electrolyte, which is either liquid or solid, depending on the design. Aluminum electrolytic capacitors have an anode, which is aluminium, and a cathode, which is a metal oxide. When a voltage is applied to the anode it causes the electrolyte to break down and create an electric double layer of ions at the metal oxide surface. This double layer of ions creates an electrical field which interacts with the metal oxide layer.

The aluminum electrolytic capacitors\' capacitance mostly depends on the anode surface area, electrolyte type and the dielectric material. The larger the anode surface area and thinner the dielectric material, the higher the capacitance. The resistance in the aluminum electrolytic capacitor comes from the leakage current flowing through the electrolyte as well as the ESR (equivalent series resistance). The higher the ESR, the heavier the energy conversion, and the larger the heat generated by the capacitor.
