Overview
The Bourns MH3261-800Y is a high current chip ferrite bead designed for surface mount applications. It features a 1206 (3216 metric) package with dimensions of 3.2 mm length, 1.6 mm width, and 1.1 mm height. The component provides an impedance of 80 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 4 A and has a maximum DC resistance of 30 mOhms. The operating temperature range spans from -55 C to +125 C.
Feature Summary
- Compact 1206 footprint suitable for dense circuit layouts
- High rated current capability for power line filtering
- Low DC resistance to minimize insertion losses
Applications
- Power supply output filtering
- Signal line noise suppression
- EMI suppression in compact electronic devices
Procurement Notes
Verify the specific suffix 'Y' against the manufacturer's latest documentation to confirm packaging and compliance details. Confirm availability status as distribution channels may vary. Ensure the selected component matches the required impedance and current ratings for the target application circuit design.
Selection Notes
Select this component when a low profile SMD ferrite bead with high current handling is required. The 1206 size offers a balance between physical space constraints and electrical performance. Verify that the 80 Ohm impedance at 100 MHz aligns with the noise spectrum of the application. Ensure the PCB layout accommodates the specified thermal and current requirements.
Part Context
This part belongs to the Bourns MH3261-T series of high current chip ferrite beads. The series is characterized by its ability to handle significant DC currents while maintaining a small form factor. These components are engineered for effective electromagnetic interference suppression in modern electronics where space and efficiency are critical design factors.
Replacement Considerations
Consult official substitution guides for compatible parts within the MH3261-T series or equivalent high current ferrite beads from other manufacturers. Verify that any substitute maintains the same 1206 footprint, 80 Ohm impedance, and 4 A current rating to ensure circuit compatibility.
