MH3261-310Y

Overview

The Bourns MH3261-310Y is a single-line differential mode ferrite bead in the MH series, housed in a 1206 (3216 metric) surface-mount package. It exhibits an impedance of 31 ohms at 100 MHz and supports a rated DC current of 3A. The component features a maximum DC resistance (DCR) of 40 milliohms. Physical dimensions are 3.20mm in length and 1.60mm in width, with a maximum height of 1.30mm.

Feature Summary

• Compact 1206 footprint designed for dense circuit layouts
• High rated current capability for power line applications
• Low DC resistance to minimize insertion losses

Applications

• Power supply filtering
• Signal line noise suppression
• EMI reduction in compact electronic devices

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's official datasheet to confirm material composition and moisture sensitivity level. Ensure the ordering quantity matches the standard tape-and-reel packaging specifications provided by Bourns Inc. Cross-reference the impedance value at 100 MHz with design requirements before finalizing procurement.

Selection Notes

Select this component when a low-profile surface-mount ferrite bead is required for high-current applications up to 3A. The 1206 package size suits space-constrained designs. Verify that the 31-ohm impedance at 100 MHz aligns with the target frequency spectrum for EMI suppression. Confirm that the 40-milliohm DCR meets the thermal and efficiency constraints of the power path.

Part Context

This part belongs to the Bourns MH3261-T series of high-current multilayer chip ferrite beads. The series is characterized by its ability to handle significant DC currents while maintaining a small physical profile. These components are engineered for effective electromagnetic interference filtering in modern electronics where space and current capacity are critical design factors.

Replacement Considerations

Consult the official Bourns replacement guide for verified substitutes within the MH series or equivalent impedance ratings. Do not assume functional interchangeability with other manufacturers' parts without verifying electrical parameters and mechanical dimensions.
