MI1206K101R-00

Overview

The MI1206K101R-00 is a single-line ferrite bead chip manufactured by Laird-Signal Integrity Products. It features a 1206 (3216 metric) surface-mount package with dimensions of 0.126 inches in length and 0.063 inches in width. The component provides an impedance of 100 ohms at 100 MHz. It has a maximum DC resistance of unspecified low value and operates within a temperature range of -40°C to 125°C. The part status is obsolete.

Feature Summary

• Provides electromagnetic interference filtering for power lines
• Designed for high-current applications in compact surface-mount layouts
• Utilizes solid ferrite core construction for signal integrity

Applications

• Power line noise suppression
• RF inductor circuits
• General EMI filtering in electronic assemblies

Procurement Notes

This component is officially listed as obsolete and no longer manufactured by the producer. Verification of current availability requires checking authorized distributors for remaining stock or approved substitute parts. Ensure compliance with environmental regulations, noting that this specific suffix version may not meet RoHS standards compared to newer alternatives.

Selection Notes

Select this part only if legacy compatibility is required, as it is discontinued. For new designs, consider the direct replacement MI1206K101R-10 which offers RoHS compliance. Verify that the 1206 footprint and 100-ohm impedance at 100 MHz match the circuit requirements before sourcing from secondary markets.

Part Context

This ferrite bead belongs to the MI series from Laird-Signal Integrity Products, specialized for EMI filtering and RF inductance. The series includes various impedances and package sizes. The MI1206K101R-00 specifically denotes the non-RoHS compliant variant in the 1206 package format, distinguishing it from the RoHS-compliant -10 suffix version.

Replacement Considerations

The direct replacement is MI1206K101R-10. This alternative maintains identical electrical characteristics and physical dimensions while offering RoHS compliance. Other similar components may require verification of impedance curves and current ratings.
