MI1206L501R-10

Overview

The MI1206L501R-10 is a monolithic ferrite chip bead from the MI series, manufactured by Laird-Signal Integrity Products. It provides electromagnetic interference (EMI) filtering for power and signal lines in surface-mount applications. The component features a 1206 (3216 metric) package with dimensions of 3.2 mm length, 2.5 mm width, and 1.4 mm height. Key electrical specifications include an impedance of 500 Ohms at a test frequency of 100 MHz, a maximum DC current rating of 2 A, and a maximum DC resistance of 60 mOhms. It operates within a temperature range of -40°C to +125°C.

Feature Summary

• Monolithic construction designed for high-current power line filtering
• Surface-mount technology compatible with standard SMD/SMT assembly processes
• Optimized for EMI suppression in both power and signal line circuits

Applications

• Power supply input filtering
• Signal line noise suppression
• DC-DC converter output stages

Procurement Notes

Verify the manufacturer designation on official datasheets, as some distributor listings may incorrectly identify the maker as Qnity while others correctly cite Laird-Signal Integrity Products. Confirm RoHS compliance status through the specific product documentation, as conflicting information exists regarding regulatory adherence. Ensure the ordering suffix matches the required packaging format, such as cut tape or reel, to align with production requirements.

Selection Notes

Select this component when a 500 Ohm impedance at 100 MHz is required for EMI attenuation in compact designs. The 2 A current rating supports moderate power applications without significant saturation effects. The 1206 footprint offers a balance between thermal performance and board space efficiency compared to smaller packages.

Part Context

This part belongs to the MI series of ferrite beads, which are engineered for general-purpose EMI filtering in consumer electronics and industrial equipment. The series utilizes monolithic ceramic technology to provide stable performance across varying environmental conditions.

Replacement Considerations

Direct substitutes include variants with different suffixes such as MI1206L501R-00 if packaging differences exist. Cross-manufacturer alternatives like Murata BLM series components may require verification of impedance curves and current ratings.
