Overview
The Bourns MF3261-301Y is a high impedance ferrite chip 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 300 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 300 mA and has a maximum DC resistance of 300 mOhms. The operating temperature range spans from -55 C to +125 C.
Feature Summary
- High impedance performance for effective noise suppression
- Surface mount design for automated assembly integration
- Robust construction suitable for demanding thermal environments
Applications
- EMI suppression in portable electronic devices
- Signal line filtering in consumer electronics
- Noise control in automotive infotainment systems
Procurement Notes
Verify the specific suffix Y against the official Bourns datasheet to confirm packaging details and material compliance. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit design. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity before finalizing procurement orders.
Selection Notes
Select this component when high impedance attenuation is required at 100 MHz within a compact 1206 footprint. Evaluate the 300 mA current limit to ensure it exceeds the peak operational current of the protected line. Consider the 300 mOhm DC resistance impact on signal integrity and power loss in low voltage applications during the schematic phase.
Part Context
This ferrite bead belongs to the MF series of chip beads manufactured by Bourns Inc. The series offers various impedance values and package sizes tailored for different EMI suppression needs. The MF3261-301Y specifically targets applications requiring moderate current handling with high frequency noise reduction capabilities in space-constrained designs.
Replacement Considerations
Consult the Bourns official cross-reference guide or contact technical support for verified substitute part numbers. Do not assume compatibility based solely on impedance and package size; verify current ratings and impedance curves.
