Aluminum electrolytic capacitors are widely used in commercial and industrial products, particularly those requiring the provision of energy storage capacity, such as audio amplifiers, computers and digital music players. The EMVA250ARA102MKE0S is an aluminum electrolytic capacitor specifically designed for applications requiring small size and high ripple current capability.

The EMVA250ARA102MKE0S is categorised as an “auto-reform” type capacitor, a relatively new variant of aluminum electrolytic capacitors that boasts of an advanced design and construction. The capacitor features a small case size, very low ESR, high ripple current ability and an ultra-long working life. This makes it suitable for a wide range of applications that require reliable and stable performance.

The EMVA250ARA102MKE0S is made up of two core components; a metalized aluminum foil with an oxide film and a pressed paper separator. It also consists of manganese dioxide, organic solvent, and electrolyte. The metalized aluminum foil forms the anode and the cathode is formed by the organic solvent and electrolyte. The current flows from the anode to the cathode through the separator, thereby forming an electrical circuit.

The working principle behind the EMVA250ARA102MKE0S is the same as any other electrolytic capacitor in operation. Just like any other capacitor, when a voltage is applied between its two leads, an electric field is induced across the separator which generates a small current through the capacitor. The current capacity of the capacitor depends on the amount of charge stored in its components, which is determined by the voltage applied across its leads. The EMVA250ARA102MKE0S also features auto-reform which recharges the capacitor after every discharge cycle, thus providing a more reliable and stable operation.

The EMVA250ARA102MKE0S is ideally suited for low frequency applications that require high ripple current and long life, such as audio power amplifiers, automotive applications, and switching power supplies. Its wide operating temperature range and superior tolerance of high ambient temperatures makes it an excellent choice for environments with temperature extremes, such as automotive and military electronics.

The compact size, combined with its low ESR, makes the EMVA250ARA102MKE0S an ideal choice for applications in areas with limited space. Electronics designers can save valuable circuit board area and reduce the possibility of electrical noise and other interference.

Thanks to its high-end performance and reliability, the EMVA250ARA102MKE0S is a popular choice in applications across various industries. From audio amplifiers to military electronics, this aluminum electrolytic capacitor is a reliable and efficient choice across a wide range of applications, delivering everything from high-capacity energy storage to low-noise performance.
