Overview
The MH2029-331T is a high-current ferrite bead from Bourns, housed in a compact 0805 (2012 metric) surface-mount package. It provides an impedance of 330 ohms at 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 2.8A and features a maximum DC resistance of 40 milliohms. It operates within a temperature range of -55°C to +125°C and complies with RoHS directives.
Feature Summary
- Compact thin profile suitable for dense PCB layouts
- High current handling capability for power lines
- Effective high-frequency noise suppression
Applications
- EMI suppression in power circuits
- Signal line filtering in mobile devices
- Noise reduction in consumer electronics
Procurement Notes
Verify the specific suffix 'T' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications. Ensure the impedance value of 330 ohms matches the design requirements for the target frequency. Confirm RoHS compliance status through the latest product documentation before finalizing procurement orders.
Selection Notes
Select this component when space constraints require a 0805 footprint but high current capacity is necessary. The low DC resistance minimizes voltage drop in power delivery paths. Evaluate the 2.8A rating against peak load currents to ensure reliable operation under thermal stress conditions defined by the operating temperature range.
Part Context
This part belongs to the MH2029-T series of high-current ferrite beads designed for EMI suppression. The series utilizes iron oxide materials to provide stable impedance characteristics across a wide frequency spectrum. It is engineered for use in portable electronics where size and current handling are critical design factors.
Replacement Considerations
Check for direct substitutes within the MH2029 series with different impedance values if signal attenuation requirements vary. Verify pin compatibility and thermal performance against other 0805 ferrite beads from alternative manufacturers before substitution.
