MH2029-151Y

Overview

The Bourns MH2029-151Y is a high-current chip ferrite bead designed for surface-mount applications. It features an impedance of 150 Ohms at 100 MHz with a tolerance of ±25%. The component supports a maximum DC current rating of 2A and has a maximum DC resistance of 100 mOhms. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 2.00mm in length, 1.20mm in width, and 1.10mm in height, corresponding to the 0805 (2012 Metric) package.

Feature Summary

• High current handling capability suitable for power line filtering
• Compact 0805 surface-mount footprint for space-constrained designs
• Wide operating temperature range for diverse environmental conditions

Applications

• Power supply output filtering
• Signal line noise suppression
• Automotive electronic circuits

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's datasheet to confirm halogen-free status and tape-and-reel packaging specifications. Ensure the ordering quantity aligns with standard reel sizes if bulk procurement is required. Cross-reference the impedance value at 100 MHz to confirm compatibility with target noise frequencies.

Selection Notes

Select this component when a 150 Ohm impedance at 100 MHz is required for high-current applications up to 2A. The low DC resistance minimizes voltage drop in power lines. Consider the 0805 package size for board space limitations and verify thermal management requirements given the self-heating characteristics under full load current.

Part Context

This part belongs to the MH2029 series of high-current chip ferrite beads from Bourns. The series offers various impedance values while maintaining consistent physical dimensions and current ratings. It is designed to replace older through-hole or larger surface-mount solutions in modern compact electronics.

Replacement Considerations

Direct substitutes include other MH2029 series variants with different impedance values if electrical parameters differ. Verify that any replacement maintains the same 0805 footprint and 2A current rating to ensure mechanical and thermal compatibility.
