Overview
The Bourns MH3261-301Y is a high-current ferrite chip bead in the MH3261-T series, designed for surface-mount applications. It features a 1206 (3216 metric) package with an impedance of 300 Ohms at 100 MHz and a tolerance of 25%. The component supports a maximum DC current of 1 A and maintains a maximum DC resistance of 200 mOhms. It operates within a temperature range of -55°C to +125°C.
Feature Summary
- High current capability suitable for dense layouts
- Low DC resistance to minimize power losses
- Compact 1206 footprint design
Applications
- EMI suppression in high-density circuit boards
- Power line filtering for high-current signals
- Signal integrity protection in compact electronic devices
Procurement Notes
Verify the specific suffix 'Y' against the manufacturer's official datasheet to confirm packaging details and compliance status. Ensure the selected variant matches the required impedance and current ratings for the target application. Cross-reference the Mouser number 652-MH3261-301Y with the original Bourns documentation to validate technical specifications before procurement.
Selection Notes
Select this component when a 1206 footprint is required for high-current EMI suppression. The 300 Ohm impedance at 100 MHz targets specific noise frequencies. Verify that the 1 A current rating and 200 mOhm DCR meet the circuit's thermal and efficiency requirements. Confirm compatibility with SMD/SMT assembly processes.
Part Context
This part belongs to the Bourns MH3261-T series of high-current chip ferrite beads. The series is characterized by its compact size, low profile, and ability to handle rated currents up to 11 A depending on the specific model. The MH3261-301Y specifically utilizes the 1206 case size to balance performance with board space constraints.
Replacement Considerations
Check the MH3261-T series for alternative impedance values or current ratings. Verify physical dimensions and electrical characteristics against other 1206 ferrite beads from different manufacturers if sourcing flexibility is needed.
