Overview
The MH3261-121Y is a high current ferrite chip bead from the MH series, manufactured by Bourns Inc. It features an SMD/SMT termination type and is housed in a 1206 (3216 metric) package with dimensions of 3.2 mm length and 1.6 mm width. The component provides an impedance of 120 ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 2 A and has a maximum DC resistance of 100 mOhms. The operating temperature range extends from -55 C to +125 C.
Feature Summary
- Designed for high current applications with low DC resistance to minimize power losses
- Compact 1206 footprint suitable for dense circuit layouts
- Wide impedance range allows for targeted EMI suppression
Applications
- Power supplies
- Battery chargers
- Portable devices
- Energy-efficient systems
Procurement Notes
Verify the specific part number MH3261-121Y against official Bourns documentation to confirm electrical parameters and physical dimensions. Ensure compatibility with surface mount assembly processes. Check for RoHS compliance status as indicated in the manufacturer's datasheet. Confirm that the 1206 package size meets the design constraints for the target application.
Selection Notes
Select this component when high current handling capability is required alongside effective EMI filtering. The low DC resistance helps maintain efficiency in power paths. The 1206 package offers a balance between current capacity and board space. Consider the 120 ohm impedance at 100 MHz for noise suppression requirements in the specified frequency range.
Part Context
This ferrite bead belongs to the MH series of high current chip beads from Bourns. These components are engineered to suppress electromagnetic interference in circuits carrying significant direct current. The series is characterized by its ability to handle high currents while maintaining low DC resistance, making it suitable for modern compact electronic designs.
Replacement Considerations
Publicly confirmed substitute part numbers for MH3261-121Y were not identified in the provided source material. Verify cross-references through official Bourns documentation or authorized distributor databases before substitution.
