MG2029-400Y

Overview

The MG2029-400Y is a single-line ferrite bead manufactured by Bourns Inc. in an 0805 (2012 Metric) surface-mount package. It provides 40 Ohms of impedance at a frequency of 100 MHz. The component has a maximum DC resistance of 200 mOhm and supports a maximum current rating of 300 mA. Designed for power and signal line applications, it effectively suppresses high-frequency noise in compact electronic circuits.

Feature Summary

• Provides effective suppression of high-frequency electromagnetic interference on power and signal lines
• Compact 0805 surface-mount footprint suitable for space-constrained designs
• Single-line configuration for straightforward integration into circuit paths

Applications

• Power supply input filtering
• Signal line noise suppression
• High-frequency EMI reduction in portable electronics

Procurement Notes

Verify the exact part number MG2029-400Y against manufacturer datasheets to ensure correct impedance and current ratings. Confirm package type and terminal finish requirements with the supplier. Check for authorized distribution channels to guarantee component authenticity and traceability.

Selection Notes

Select this component when a low-profile ferrite bead is required for 100 MHz noise attenuation. Ensure the operating current does not exceed 300 mA to prevent saturation. Verify that the 200 mOhm DCR meets the voltage drop constraints of the specific circuit design.

Part Context

This component belongs to Bourns' MG series of ferrite beads, designed for general-purpose noise suppression. The MG series offers various impedance values and current ratings in standard packages to support diverse electronic applications requiring EMI control.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement matches the 0805 package, 40 Ohm @ 100 MHz impedance, and 300 mA current rating.
