MH1608-221Y

Overview

The Bourns MH1608-221Y is a surface-mount ferrite bead designed for electromagnetic interference suppression in power and signal lines. It features an impedance of 220 Ohms at 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 2A and exhibits a maximum DC resistance of 100 milliohms. Housed in a compact 0603 (1608 metric) package measuring 1.60mm x 0.80mm x 0.95mm, it operates within a temperature range of -55°C to 150°C. This AEC-Q200 qualified device is suitable for automotive applications.

Feature Summary

• Provides effective electromagnetic interference suppression for sensitive circuits
• Automotive-grade construction compliant with AEC-Q200 standards
• High current handling capability for power line filtering
• Compact surface-mount footprint for space-constrained designs

Applications

• Power supply input/output filtering
• Battery charger circuit protection
• Portable electronic device signal integrity enhancement
• Automotive electronics EMI mitigation

Procurement Notes

Verify the specific suffix 'Y' corresponds to the required tape-and-reel packaging configuration. Confirm that the 2A rated current aligns with the peak operational demands of the target circuit. Ensure the 100 milliohm maximum DC resistance meets voltage drop constraints. Validate compliance with RoHS 3 directives if required by the end product specifications.

Selection Notes

Select this component when high current capacity is required alongside moderate impedance values. The 0603 package offers a balance between thermal performance and board space efficiency. Consider the 220 Ohm impedance profile for frequencies around 100 MHz. Verify that the operating temperature range covers the environmental conditions of the final assembly.

Part Context

This part belongs to the Bourns MH1608 series of ferrite beads. The series is characterized by its ability to handle high currents while maintaining low DC resistance. These components are widely used in modern electronics where size reduction and reliability are critical. The MH1608 series specifically targets applications requiring robust EMI filtering in compact form factors.

Replacement Considerations

Check for direct substitutes from other manufacturers offering identical 220 Ohm impedance at 100 MHz and 2A current rating in a 0603 package. Ensure any replacement maintains AEC-Q200 qualification if used in automotive contexts. Verify pin compatibility and thermal characteristics before substitution.
