Overview
The MH2029-101Y is a high-current chip ferrite bead manufactured by Bourns Inc. It features a 0805 (2012 Metric) surface-mount package with dimensions of 2.00mm x 1.25mm and a maximum height of 1.10mm. The component provides an impedance of 100 Ohms at 100 MHz with a tolerance of ±25%. It supports a maximum DC current rating of 2A and has a maximum DC resistance (DCR) of 0.1 Ohm. The device operates within a temperature range of -55°C to +125°C and is RoHS compliant.
Feature Summary
- Designed for high-current applications in power and signal line filtering
- Compact 0805 surface-mount footprint for space-constrained PCB layouts
- Robust thermal performance suitable for wide industrial temperature ranges
Applications
- Power supply input/output filtering
- High-speed digital signal line noise suppression
- Automotive electronics circuit protection
Procurement Notes
Verify the specific suffix and manufacturing date code upon ordering, as component specifications may vary between production batches. Confirm that the replacement part meets all electrical requirements, including impedance curves and current ratings, before finalizing integration into the design. Ensure compliance with relevant environmental regulations such as RoHS3 for the target market.
Selection Notes
Select this component when a compact ferrite bead capable of handling 2A continuous current is required. The 0805 package offers a balance between current capacity and board space efficiency. Consider the 100 Ohm impedance at 100 MHz for targeting specific noise frequencies in power delivery networks or data lines.
Part Context
This component belongs to the MH Series of high-current chip ferrite beads from Bourns. These components are engineered to suppress electromagnetic interference (EMI) in high-density electronic assemblies. The series is widely used in consumer electronics, telecommunications, and automotive systems where reliable noise filtration is critical for signal integrity.
Replacement Considerations
The Samsung Electro-Mechanics CIC21P101NE is listed as a similar substitute. Verify mechanical compatibility and exact impedance characteristics before substitution.
