MH3261-900Y

Overview

The Bourns MH3261-900Y is a high-current ferrite bead in a 1206 (3216 metric) surface-mount package. It provides an impedance of 90 Ohms at 100 MHz and supports a rated current of 3 A with a maximum DC resistance of 40 mOhm.

Feature Summary

• Compact 1206 footprint designed for dense circuit layouts
• High current handling capability for power and signal lines
• Low DC resistance to minimize insertion losses

Applications

• Power line filtering
• Signal line noise suppression
• EMI mitigation in compact electronics

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's official datasheet to confirm impedance tolerance and tape-and-reel packaging specifications. Ensure the component meets the required temperature rating and current derating curves for the intended operating environment before finalizing procurement.

Selection Notes

Select this component when space constraints require a 1206 footprint but high current capacity is necessary. The 90 Ohm impedance at 100 MHz targets specific EMI frequencies, while the low DCR ensures efficiency in power delivery paths where voltage drop must be minimized.

Part Context

This part belongs to the MH3261-T series of high-current chip ferrite beads from Bourns. The series is characterized by its ability to handle high currents up to 11 A in some variants, offering a balance between size, current rating, and noise suppression performance for modern electronic designs.

Replacement Considerations

Consult the official Bourns datasheet for direct cross-reference part numbers or alternative series within the MH3261 family that match the 90 Ohm @ 100 MHz impedance and 3 A current requirements.
