Overview
The MH2029-601Y is a high current chip ferrite bead from the Bourns MH series, designed for surface mount technology. It features an impedance of 600 ohms with a tolerance of ±25% at a test frequency of 100 MHz. The component supports a maximum DC current of 1 A and has a maximum DC resistance of 200 mOhms. Housed in an 0805 (2012 metric) package measuring 2 mm x 1.2 mm x 0.9 mm, it operates within a temperature range of -55°C to +125°C.
Feature Summary
- Engineered for high current applications with optimized magnetic properties
- Provides effective electromagnetic interference suppression in compact form factors
- Designed for reliable surface mount integration into dense circuit layouts
Applications
- High current power line filtering
- Electromagnetic interference suppression in portable devices
- Signal integrity protection in data lines
Procurement Notes
Verify the specific suffix 'Y' corresponds to the required packaging configuration, such as reel or cut tape, as indicated by distributor listings. Confirm that the 0805 footprint matches the target PCB design. Ensure the 1 A current rating and 600 Ohm impedance align with the circuit's noise suppression requirements and thermal constraints before finalizing procurement.
Selection Notes
Select this component when high current handling capability is critical alongside EMI suppression. The 0805 package offers a balance between current capacity and board space efficiency compared to smaller footprints. Verify that the 200 mOhm DC resistance meets voltage drop limitations in the power path. Consider the operating temperature range if deployed in harsh environments.
Part Context
This part belongs to the MH series of high current chip ferrite beads manufactured by Bourns. The series is characterized by its ability to handle significant DC bias currents while maintaining effective impedance characteristics for noise filtering. The MH2029-601Y specifically utilizes the 0805 case size to accommodate higher current demands than standard miniature beads.
Replacement Considerations
Direct substitutes must match the 600 Ohm impedance, 1 A current rating, and 0805 footprint. Check manufacturer datasheets for equivalent parts in the MH series or competing brands offering similar high-current specifications. Ensure compatibility with reflow soldering profiles and verify that alternative components meet the same RoHS compliance standards.
