MI1206K310R-00

Overview

The MI1206K310R-00 is a single-line ferrite bead chip from the MI series, manufactured by Laird-Signal Integrity Products. It features a 1206 (3216 metric) surface-mount package with dimensions of 3.20mm x 1.60mm and a maximum height of 1.4mm. The component provides an impedance of 31 Ohms at 100 MHz and supports a maximum DC current of 1.5A. Its maximum DC resistance is 45 mOhms. It operates within a temperature range of -40°C to +125°C and is classified as a differential mode power filter.

Feature Summary

• Provides electromagnetic interference filtering for power and signal lines
• Designed for high-current applications with low DC resistance
• Monolithic construction in a compact surface-mount footprint

Applications

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

Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates non-compliance for this specific suffix. Confirm the exact impedance value and current rating against the target circuit requirements. Check for direct replacement part numbers if availability is a concern due to discontinuation status.

Selection Notes

Select this component when a 31 Ohm impedance at 100 MHz is required for a single-line application. Ensure the PCB layout accommodates the 1206 package size. Verify that the 1.5A current rating meets the peak load requirements of the circuit without causing excessive saturation or heating.

Part Context

This component belongs to the MI series of ferrite beads, which are engineered for general-purpose EMI suppression. It serves as a passive filter element to attenuate high-frequency noise on conductors. The product is listed as obsolete, indicating it has been replaced by newer iterations in the manufacturer's portfolio.

Replacement Considerations

The direct replacement part number is MI1206K310R-10. Alternative similar components include BLM31PG330SN1L from Murata Electronics.
