Overview
The MU3261-122Y is a high impedance ferrite chip bead manufactured by Bourns Inc. in the MU series. It features an SMD/SMT termination style within a 1206 (3216 metric) package, measuring 3.2 mm in length and 1.6 mm in width. The component provides an impedance of 1200 ohms at 100 MHz with a tolerance of 25%. It supports a maximum DC current of 900 mA and has a maximum DC resistance of 150 mohms. The device operates reliably within a temperature range of -55°C to +125°C.
Feature Summary
- High impedance performance for effective EMI suppression
- Compact 1206 surface mount footprint
- Wide operating temperature range
Applications
- EMI suppression in high-frequency applications
- Signal integrity protection in electronic circuits
Procurement Notes
Verify the specific part number MU3261-122Y against official manufacturer documentation to confirm availability status. Some sources indicate this specific variant may be End-of-Life or discontinued. Ensure compatibility with design requirements before procurement. Cross-reference datasheets from authorized distributors to validate current stock levels and lead times. Confirm RoHS compliance details as per the latest product specifications.
Selection Notes
Select this component when high impedance at 100 MHz is required for noise filtering. The 1206 package offers a balance between size and current handling capability. Consider the 900 mA current rating for power line applications. Verify thermal management needs given the wide operating temperature range. Compare impedance characteristics against other ferrite beads in the MU series for optimal circuit performance.
Part Context
This ferrite bead belongs to Bourns' MU series of high impedance chip beads. The series includes various impedance values tailored for different frequency suppression needs. The MU3261-122Y specifically targets higher impedance requirements compared to lower value variants like the 120 ohm version. It shares the same physical dimensions and general electrical characteristics with other parts in the 1206 package family.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided data. Check for direct replacements within the MU3261 series such as MU3261-121Y or MU3261-221Y if impedance differences are acceptable. Consult manufacturer guidelines for cross-referencing alternatives.
