Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are generally composed of two aluminum foils wound together and coated with electrolyte paste, and sealed in a metal can. They are used in power supplies, audio equipment, power amplifiers, filters, timing circuits and other electronic products. The ELBK250ELL952ALP1S is a type of aluminum electrolytic capacitor.

Application Field

The ELBK250ELL952ALP1S capacitor is a high-frequency, long-life aluminum electrolytic capacitor with a rated temperature range from -55°C to +150°C. It features very low ESR and high ripple current ratings for extended life, making it a cost-effective solution for applications such as automotive electronic systems, small appliances, and sophisticated power supplies. It is available in radial and axial leaded versions and is compatible with automated placement machines.

Working Principle

An aluminum electrolytic capacitor is a capacitor in which aluminium serves as an anode which is partially or wholly covered in an electrolyte, usually a mixture of of borax and water or a specialized electrolyte such as glycol or ethylene glycol. It is different from the non-polarized aluminum capacitor because two layers of aluminium are used in the anode, as opposed to one. These two layers of aluminium are isolated from each other by a rippled dielectric barrier (which has higher surface area and allows for greater capacitance size). The electrolytic capacitors also utilizes a back compartment in order to create an anode compartment that increases the capacitance size to have higher values than what non-polarized aluminum capacitors can offer.

The ELBK250ELL952ALP1S tantalum capacitor has an ESR rating of 4mΩ, and is capable of discharging up to 3.0A of ripple current at 120Hz with 0.45 Voltage ripple. Moreover, it features a wide voltage range of 25V-100VDC, which makes it suitable for power supply applications in automotive, aerospace and consumer electronics.

In addition to its high ESR and low ripple current ratings, the ELBK250ELL952ALP1S has a very high voltage handling capability of up to 100V DC. This makes it useful for high voltage, high frequency applications such as power supplies, filtering circuits, and MOSFET drive circuits. Moreover, its low internal resistance also improves its self-heating capability, allowing for increased power dissipation.

The ELBK250ELL952ALP1S is a highly reliable capacitor suitable for applications that require long operating life and minimal energy loss. Its reasonable pricing and high performance make it a popular choice for video and audio applications, power supplies, and battery charging circuits.
