Aluminum Electrolytic Capacitors: EKMS401VSN221MA20S Application Field and Working Principle

Aluminum electrolytic capacitors, often referred to as “aluminium caps”, are widely used in electrical electronic components due to their small size, high energy density and low cost. The element of an aluminum electrolytic capacitor is comprised of the positive and negative terminal “posts” with a thin film “dielectric” layer between them. The “posts” of the element are typically made of aluminum and are held together with a “case” which houses a liquid electrolyte solution that facilitates the electric charge. CAPXON’s EKMS401VSN221MA20S Aluminum Electrolytic Capacitor is a premium quality capacitor that features a long service life, excellent insulation properties, and is RoHS compliant.

The EKMS401VSN221MA20S Aluminum Electrolytic Capacitor is primarily used in consumer electronic devices, automotive, and home appliance applications. A benefit of this capacitor is its ability to store large amounts of energy quickly. This capacitor is also able to handle high current along with its compact size which can provide convenience in tight space applications. The long lifetime of up to 2000 hours also ensures efficiency for home appliance and industrial equipment.

The EKMS401VSN221MA20S Aluminum Electrolytic Capacitor is made up of two aluminum plates connected together by a thin film layer of an aluminum oxide dielectric. On the negative plates a porous material is used which allows the electrolyte solution seal the element. During the operation of the capacitor, the electrons created when the positive and negative electrodes are connected is pulled into the porous material of the negative plates where oxygen will be extracted from the electrolyte solution. This process forms the electrolytic oxide layer on the plate which is the dielectric of the capacitor. This dielectric provides the capacitor with a high level of capacitance.

The EKMS401VSN221MA20S Aluminum Electrolytic Capacitor also has a wide range of temperature possible operation, up to 105°C withstanding voltage which can ensure its reliability in harsh environments. It also has excellent rating in terms of its temperature coefficient of capacitance, which range from -30 to +85°C. Additionally, the pad size and its lead pitch of 0.95mm gives the manufacturer and designer the convenience in optimizing the design of the boards with less effort.

The EKMS401VSN221MA20S Aluminum Electrolytic Capacitor is one of the most widely used capacitors available in the market, due to its high level of capacitance, low ESR, low impedance, high temperature operation, and long lifetime capabilities. These features make it suitable for a wide range of applications from consumer electronic devices to home appliances and automotive and industrial equipment. Its superior insulation properties and RoHS compliance makes this capacitor ideal for applications in highly sensitive environments. Its convenience in the pad size and lead pitch design also ensures efficient and cost-effective production.
