MZ2029-202Y

Overview

The MZ2029-202Y is a surface-mount ferrite bead manufactured by Bourns Inc. in the 0805 (2012 Metric) package. It provides an impedance of 2 kOhms at 100 MHz and supports a maximum current rating of 50 mA. The component features a low DC resistance of 600 mOhm and has a maximum height of 1.10 mm. Designed for single-line applications, it serves as a passive filter to suppress electromagnetic interference in power and signal circuits.

Feature Summary

• Provides high impedance attenuation for noise suppression in single-line configurations
• Compact surface-mount design suitable for space-constrained PCB layouts
• Low DC resistance minimizes voltage drop across the filtered line

Applications

• Power line filtering in portable electronic devices
• Signal line noise suppression in communication modules
• Electromagnetic interference mitigation in consumer electronics

Procurement Notes

Verify the complete part number including suffixes against official Bourns documentation to ensure correct impedance and tolerance specifications. Confirm RoHS compliance status and lead times through authorized distributors. Ensure storage conditions meet manufacturer requirements to maintain material integrity prior to assembly.

Selection Notes

Select this component when a compact ferrite solution with 2 kOhm impedance at 100 MHz is required. Verify that the 50 mA current rating meets the circuit's operational demands. Consider the 600 mOhm DC resistance impact on signal integrity or power efficiency before finalizing the design.

Part Context

This ferrite bead belongs to Bourns' passive component portfolio, which includes resistors, capacitors, and inductors. The MZ2029 series is designed for general-purpose EMI suppression. It complements other Bourns protection devices used in automotive, industrial, and consumer markets to ensure signal purity and system reliability.

Replacement Considerations

Consult official Bourns substitution guides for compatible alternatives. Verify that any substitute matches the 0805 footprint, 2 kOhm @ 100 MHz impedance, and 50 mA current rating. Ensure equivalent DC resistance and temperature characteristics are maintained.
