Overview
The Bourns MH3261-501Y 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 500 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current rating of 3 A and has a maximum DC resistance of 40 mOhms. The operating temperature range spans from -55°C to +125°C.
Feature Summary
- High current capability suitable for power and signal line filtering
- Low DC resistance minimizes power losses in the circuit
- Compact 1206 footprint facilitates dense layout designs
Applications
- EMI suppression on power lines
- Signal line noise filtering
- High current circuit protection
Procurement Notes
Verify component status as the MH3261-501Y is listed as End-of-Life (EOL). Confirm availability through authorized distributors or secondary market sources. Check RoHS compliance details and specific manufacturing dates against project requirements. Ensure replacement strategies are evaluated due to discontinuation status.
Selection Notes
Select this component when high current handling up to 3 A is required alongside significant impedance at 100 MHz. The low DCR of 40 mOhms makes it efficient for power integrity. Consider the 1206 package size for board space constraints. Verify thermal performance within the -55°C to +125°C range for the specific application environment.
Part Context
This part belongs to the Bourns MH series of high current chip ferrite beads. The series offers various impedance values tailored for different filtering needs while maintaining high current ratings. The MH3261-501Y specifically targets applications requiring robust EMI suppression in compact surface mount layouts.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, alternative components from other manufacturers or different Bourns series may require re-evaluation of electrical parameters and mechanical fit.
