MG1608-400Y

Overview

The MG1608-400Y is a single-line ferrite bead manufactured by Bourns Inc. in the 0603 (1608 metric) surface-mount package. It exhibits an impedance of 40 Ohms at 100 MHz and supports a maximum current rating of 300 mA. The component features a low DC resistance of 300 mOhms with a tolerance of ±25%. Designed for power and signal line filtering, it provides effective noise suppression in compact electronic circuits.

Feature Summary

• Provides electromagnetic interference suppression for power and signal lines
• Compact 0603 surface-mount footprint for space-constrained designs
• Low DC resistance to minimize voltage drop in high-current applications

Applications

• Power supply input/output filtering
• Battery charger circuit noise reduction
• Voltage regulation stage decoupling

Procurement Notes

Verify the manufacturer part number MG1608-400Y against official Bourns documentation to confirm specifications. Ensure compatibility with 0603 soldering profiles. Check RoHS compliance status if required by project standards. Confirm availability through authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a 40 Ohm impedance at 100 MHz is required for EMI filtering in small form factors. The 300 mA current rating suits moderate power applications. Consider the 300 mOhm DC resistance impact on circuit efficiency. Verify thermal performance under continuous load conditions.

Part Context

This ferrite bead belongs to Bourns' standard chip ferrite bead series designed for general-purpose noise suppression. The MG1608 series offers various impedance values in the 0603 package. It complements other passive components in power management and signal integrity solutions.

Replacement Considerations

Consult official substitution guides for equivalent ferrite beads with matching 40 Ohm @ 100 MHz impedance and 0603 package dimensions. Verify current ratings and DC resistance limits before cross-referencing.
