MH2029-401Y

Overview

The MH2029-401Y is a high-current ferrite chip bead manufactured by Bourns Inc. It features an impedance of 400 ohms with a tolerance of 25%. Designed for surface mount applications, it utilizes the 0805 (2012 metric) package with dimensions of 2 mm length, 1.2 mm width, and 0.9 mm height. The component operates within a temperature range of -55°C to +125°C and is RoHS compliant.

Feature Summary

• High current handling capability suitable for power line filtering
• Single-line configuration for signal and power circuit noise suppression
• Compact 0805 surface mount footprint for space-constrained designs

Applications

• Power supply input filtering
• Signal line noise suppression
• Electromagnetic interference (EMI) reduction in compact electronics

Procurement Notes

Verify the specific manufacturer part number against official Bourns documentation to ensure accuracy. Confirm that the required impedance value and current rating align with the design specifications. Check for RoHS compliance status if environmental regulations apply to the final product assembly.

Selection Notes

Select this component when high current capacity is required alongside significant impedance at target frequencies. The 0805 package offers a balance between current handling and board space efficiency. Ensure the operating temperature range meets the environmental requirements of the intended application.

Part Context

This component belongs to the MH2029 series of high-current ferrite beads from Bourns. The series provides robust noise filtering solutions for modern electronic circuits where standard ferrite beads may saturate under high load conditions.
