ASPI-8040S-390M-T Description

Short technical summary and product information.

The Abracon ASPI-8040S-390M-T is a shielded wirewound surface-mount power inductor from the ASPI-8040S series. It offers a nominal inductance of 39 µH with a ±20% tolerance and a saturation current rating of 1.95 A. The inductor's DC resistance is 107 mΩ, and its minimum self-resonant frequency is 7.8 MHz.

 

This component is designed for DC-DC converter applications, providing high energy storage and low radiation due to its shielded ferrite core construction. The drum core, wirewound design ensures reliable performance in power supply circuits.

 

The inductor measures 8.00 mm by 8.00 mm with a height of 4.20 mm, and comes in a nonstandard surface-mount package. It is rated for operation over a temperature range of -40°C to +125°C, making it suitable for a variety of environments.

 

With its low DCR and high current handling, this inductor is ideal for use in portable communication equipment, OA equipment, and other DC-DC converter applications.
