Overview
The MH1005-471Y is a high-current surface-mount ferrite bead from the Bourns MH1005 series, housed in a compact 0402 (1005 metric) package with dimensions of 1.0mm x 0.5mm x 0.5mm. It provides an impedance of 470 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current rating of 1.1A and features a maximum DC resistance of 180 mOhms. It operates within a temperature range of -55°C to +125°C.
Feature Summary
- Compact low-profile 0402 footprint designed for space-constrained PCB layouts
- High current handling capability suitable for power line filtering applications
- Surface mount termination type for automated assembly processes
Applications
- Power supply output filtering
- DC-DC converter noise suppression
- Signal integrity protection on data lines
Procurement Notes
Verify the specific suffix 'Y' against the manufacturer's latest datasheet to confirm tape and reel packaging specifications and RoHS compliance status. Ensure the ordering quantity aligns with standard reel sizes provided by authorized distributors. Cross-reference the part number with official Bourns documentation to validate availability and lead times prior to procurement planning.
Selection Notes
Select this component when a small form factor is required alongside moderate current carrying capacity. The 470 Ohm impedance value targets specific noise frequencies around 100 MHz. Compare the 1.1A current rating against peak load requirements to prevent saturation. Consider the 180 mOhm DCR impact on voltage drop in sensitive power rails.
Part Context
This part belongs to the Bourns MH1005 series of compact high-current ferrite beads. The series is engineered to provide effective electromagnetic interference suppression in minimal board space. The MH1005 designation indicates the 0402 case size, distinguishing it from larger series like MH2012 or MH2016 which offer higher current ratings but require more PCB area.
Replacement Considerations
Direct substitutes include other 0402 ferrite beads with similar 470 Ohm impedance and >1A current ratings. Verify that alternative components match the 180 mOhm maximum DC resistance and 100 MHz test frequency specifications to ensure equivalent circuit performance.
