28F0121-1SR-10

Overview

The 28F0121-1SR-10 is a single-line ferrite bead manufactured by Laird-Signal Integrity Products, designed for power line EMI filtering. It features a 2-SMD J-Lead surface mount package with dimensions of 3.05 mm in length, 2.54 mm in width, and a maximum height of 3.05 mm. The component exhibits an impedance of 96 Ohms at 100 MHz and supports a maximum rated current of 10A. Its maximum DC resistance (DCR) is specified as 1 mOhm. The device operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides broadband frequency noise suppression for power lines through high impedance characteristics.

Applications

• Power supply input filtering
• DC bus decoupling
• High-current signal line protection

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with RoHS directives if required by the target application environment. Cross-reference the DigiKey part number 240-1002-2-ND or TTI listings for accurate sourcing channels and lead times from authorized distributors.

Selection Notes

Select this component when high current handling capability near 10A is required alongside significant attenuation at 100 MHz. The J-lead package facilitates robust surface mounting on PCBs where space constraints allow for the 3312 footprint. Evaluate thermal management requirements given the low DC resistance and high current rating to ensure stable operation under load.

Part Context

This ferrite bead belongs to Laird-Signal Integrity Products' lineup of passive components aimed at electromagnetic interference mitigation. It serves as a critical element in maintaining signal integrity and compliance with emission standards in electronic circuits. The product is categorized under ferrite beads and chips, distinct from inductors or resistors, focusing specifically on lossy absorption of high-frequency noise.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult the manufacturer's catalog for direct equivalents or functional alternatives that match the 96 Ohm impedance at 100 MHz and 10A current rating specifications.
