MH4516-800Y

Overview

The MH4516-800Y is a high current chip ferrite bead from the Bourns MH series, designed for surface mount applications in the 1806 (4516 metric) package. It exhibits an impedance of 80 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 3 A and has a maximum DC resistance of 50 mOhms. It operates within a temperature range of -55°C to +125°C and measures 4.5 mm in length, 1.6 mm in width, and 1.6 mm in height.

Feature Summary

• High current handling capability rated at 3 A
• Robust construction resistant to heat, humidity, mechanical shock, and pressure
• Accurate dimensions optimized for automatic surface mounting processes

Applications

• Power line filtering
• Signal line noise suppression
• High current circuit protection

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's latest documentation to confirm packaging configuration and compliance status. Ensure the ordering information matches the required impedance tolerance and current rating specifications for the target application environment.

Selection Notes

Select this component when designing circuits requiring significant current capacity alongside EMI suppression. The 1806 footprint provides a balance between physical size and thermal performance. Confirm that the 80 Ohm impedance value aligns with the noise frequencies present in the specific power or signal lines being filtered.

Part Context

This part belongs to the MH series of high current chip ferrite beads manufactured by Bourns Inc. The series includes various impedance values and package sizes, such as MH4532 and MH20 variants, allowing designers to choose appropriate components based on space constraints and electrical requirements.

Replacement Considerations

Compatible substitutes include other 80 Ohm ferrite beads in the 1806 package with similar current ratings. Verify pin compatibility and impedance curves before substitution.
