MU2029-221Y

Overview

The MU2029-221Y is a high-impedance ferrite bead manufactured by Bourns Inc. in the MH series. It features a 0805 surface-mount package with dimensions of 2.0 mm length, 1.2 mm width, and 0.9 mm height. The component provides an impedance of 220 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It has a maximum DC resistance of 100 mOhms and operates within a temperature range of -55°C to +125°C.

Feature Summary

• High impedance design for effective electromagnetic interference suppression
• Compact 0805 surface-mount footprint for space-constrained layouts
• Wide operating temperature range suitable for diverse environmental conditions

Applications

• EMI suppression in power supply lines
• Signal line filtering in high-frequency circuits
• Noise reduction in digital communication interfaces

Procurement Notes

Verify the specific part number suffix against official Bourns documentation to ensure correct impedance and current ratings. Confirm RoHS compliance status through the manufacturer's latest datasheet or environmental declaration. Cross-reference ordering information with authorized distributors to avoid counterfeit components. Ensure storage conditions align with manufacturer guidelines for surface-mount devices.

Selection Notes

Select this component when high impedance is required at 100 MHz for noise attenuation. The 0805 package size offers a balance between current handling capability and board space efficiency. Consider the 100 mOhms DC resistance for voltage drop calculations in low-voltage applications. Verify thermal performance requirements against the specified operating temperature range.

Part Context

This ferrite bead belongs to Bourns' MH series of chip beads, designed for general-purpose EMI suppression. The series includes various impedance values and package sizes to accommodate different circuit requirements. Ferrite beads in this category function as passive components that dissipate high-frequency noise energy as heat.

Replacement Considerations

Check for direct substitutes from Bourns with identical impedance and package dimensions. Evaluate alternative manufacturers offering 0805 ferrite beads with 220 Ohms impedance at 100 MHz. Ensure replacement parts meet the same DC resistance and temperature rating specifications.
