ASPI-0403-390K-T

Fixed Inductors Overview

The ASPI-0403-390K-T is a fixed power inductor from Abracon LLC, featuring a 39 µH nominal inductance with ±10% tolerance. It utilizes an unshielded drum core wirewound construction and supports surface mount installation. The component operates within a temperature range of -40°C to +85°C. Key electrical specifications include a maximum DC current rating of 520 mA and a maximum DC resistance (DCR) of 587 mΩ. The physical dimensions are 4.50 mm in length, 4.00 mm in width, and 3.50 mm in height.

Fixed Inductors Feature Summary

• Unshielded drum core wirewound design for specific magnetic field requirements
• Surface mount package suitable for automated PCB assembly processes
• Robust thermal performance across extended industrial temperature ranges

Fixed Inductors Applications

• General purpose power supply filtering circuits
• DC-DC converter input and output stages
• Signal processing and energy storage applications

Fixed Inductors Procurement Notes

Verify the exact ordering suffix and packaging configuration against the manufacturer's latest documentation before purchase. Confirm that the specified tolerance and current ratings align with the target circuit requirements. Ensure compliance with RoHS directives and check for any regional export control classifications relevant to the procurement destination.

Fixed Inductors Selection Notes

Select this component when an unshielded inductor is required to minimize electromagnetic interference coupling or when cost-effective general-purpose filtering is needed. The 39 µH value and 520 mA current rating make it suitable for low-to-medium power applications. Consider the physical footprint constraints as the 4.0 x 4.5 mm size fits standard compact layouts.

Fixed Inductors Part Context

This part belongs to the ASPI series of fixed inductors manufactured by Abracon LLC. The series offers various inductance values and current ratings tailored for different power management needs. The ASPI-0403-390K-T specifically addresses applications requiring moderate inductance with a non-shielded core structure.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 39 µH inductance, 520 mA current rating, and 4.0x4.5x3.5 mm footprint. Verify that alternative components maintain the same unshielded drum core construction and operate within the -40°C to +85°C temperature range.
