Overview
The MH2029-300Y is a high current chip ferrite bead manufactured by Bourns. It features an impedance of 30 ohms at 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 3 A and has a maximum DC resistance of 25 mohms. It operates within a temperature range of -55°C to +125°C. The device utilizes a surface mount 0805 package, measuring 2 mm in length, 1.2 mm in width, and 0.9 mm in height.
Feature Summary
- Designed for high current applications in power supply circuits
- Provides effective electromagnetic interference suppression at 100 MHz
- Compact surface mount construction suitable for space-constrained designs
Applications
- Power supply filtering
- Signal line noise suppression
- Electromagnetic interference reduction in electronic devices
Procurement Notes
Verify the specific impedance value and current rating against the official Bourns datasheet before procurement. Confirm that the 0805 package dimensions align with the target PCB layout requirements. Ensure the operating temperature range meets the environmental conditions of the intended application. Cross-reference the manufacturer part number to avoid confusion with similar series components.
Selection Notes
Select this component when high current handling capability is required alongside noise suppression. The 3 A rating makes it suitable for power lines where standard beads may saturate. Consider the 30 ohm impedance profile for the specific frequency range of interest. Evaluate the low DC resistance to minimize voltage drop and power loss in the circuit path.
Part Context
This part belongs to the MH2029 series of high current chip ferrite beads from Bourns. The series offers various impedance values tailored for different filtering needs while maintaining robust current handling. The MH2029 series is designed for surface mount technology, providing reliability in compact electronic assemblies.
Replacement Considerations
Check for direct substitutes within the MH2029 series or other Bourns ferrite bead lines with matching 0805 footprints. Verify that any replacement maintains the 3 A current rating and similar impedance characteristics at 100 MHz.
