MH3261-101Y

Overview

The Bourns MH3261-101Y is a high current chip ferrite bead designed for electromagnetic interference (EMI) suppression in compact surface-mount layouts. It features a 1206 (3216 metric) package with dimensions of 3.2 mm length and 1.6 mm width. The component provides an impedance of 100 ohms at a test frequency of 100 MHz, with a tolerance of 25%. It supports a maximum DC current of 3 A and maintains a maximum DC resistance of 40 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• High current capability suitable for dense circuit layouts
• Low DC resistance to minimize power losses
• Robust construction resistant to heat, humidity, mechanical shock, and pressure

Applications

• Power supply line filtering
• DC-DC converter output stages
• General EMI suppression in portable electronics

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's latest documentation to confirm packaging details and availability status. Cross-reference the part number with official Bourns databases to ensure compliance with current RoHS directives and material declarations before finalizing procurement specifications.

Selection Notes

Select this component when high current handling is required alongside moderate impedance values in a standard 1206 footprint. Ensure the application current remains below the 3 A rating to prevent saturation. Verify that the low DC resistance meets the efficiency requirements of the target power rail.

Part Context

This component belongs to the MH series of high current chip ferrite beads from Bourns. The series is engineered for applications demanding significant current capacity while maintaining effective noise suppression in space-constrained environments.

Replacement Considerations

Consult official Bourns substitution guides for verified equivalents. Generic cross-references may not match the specific high-current ratings or impedance characteristics of this model.
