MH1608-121Y

Overview

The Bourns MH1608-121Y is a high-current chip ferrite bead in a 0603 (1608 metric) SMD package. It provides an impedance of 120 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 2 A and has a maximum DC resistance of 100 mOhms. It operates within a temperature range of -55°C to +125°C. Physical dimensions are 1.6 mm length, 0.8 mm width, and 0.8 mm height.

Feature Summary

• Designed for effective noise filtering in high-current applications
• Surface mount construction for automated assembly
• Robust thermal performance across extended industrial temperature ranges

Applications

• High-speed data line filtering
• Power supply output decoupling
• EMI suppression in compact mobile devices

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's official datasheet to confirm packaging type and compliance status. Ensure the ordering quantity aligns with the manufacturer's standard reel or cut tape specifications. Cross-reference the RoHS documentation directly from Bourns Electronic Solutions to validate environmental compliance requirements for your specific manufacturing process.

Selection Notes

Select this component when circuit design requires significant current handling capability alongside EMI suppression in a minimal footprint. The 2 A rating distinguishes it from lower-current alternatives in the same series. Verify that the 120 Ohm impedance at 100 MHz matches the target noise frequency spectrum. Confirm that the 0603 package fits the available PCB real estate constraints.

Part Context

This part belongs to the Bourns MH series of high-current chip ferrite beads. The MH1608A series designation indicates the specific product line utilizing advanced materials for improved performance. These components are engineered to replace traditional wire-wound inductors where space is limited but current capacity remains critical for signal integrity.

Replacement Considerations

Consult the official Bourns MH series datasheet for direct pin-compatible substitutes with identical impedance and current ratings. Verify that any alternative maintains the 0603 footprint and 2 A DC current handling capability.
