MH1005-301Y

Overview

The Bourns MH1005-301Y is a high current chip ferrite bead from the MH1005 series, designed for surface mount applications. It features a compact 0402 (1005 metric) package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 300 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 1.2 A and has a maximum DC resistance of 150 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• High current handling capability in a low-profile surface mount package
• Compact physical dimensions suitable for space-constrained designs
• Wide operating temperature range for diverse environmental conditions

Applications

• EMI suppression in portable electronic devices
• Signal line filtering in consumer electronics
• Power distribution network noise reduction

Procurement Notes

Verify the specific suffix and packaging configuration when ordering, as availability may vary between cut tape, reel, or specialized formats like MouseReel. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the selected supplier provides valid traceability data for quality assurance purposes.

Selection Notes

Select this component when a small footprint is required alongside moderate current carrying capacity. The 300 Ohm impedance value targets specific noise frequencies around 100 MHz. Compare the 1.2 A rating against circuit requirements to ensure adequate margin under peak load conditions without exceeding thermal limits.

Part Context

This part belongs to the Bourns MH1005 series of high current chip ferrite beads. The series is characterized by its ability to manage significant DC currents while maintaining a minimal profile. Other variants in the series offer different impedance values and current ratings within the same 0402 mechanical envelope.

Replacement Considerations

Check datasheets for alternative ferrite beads with identical 0402 dimensions and similar impedance-current characteristics. Verify that substitute components meet the same thermal and electrical specifications for direct replacement.
