MI1206L391R-10

Overview

The MI1206L391R-10 is a single-line differential mode ferrite chip bead manufactured by Laird-Signal Integrity Products. It features a 1206 (3216 metric) surface-mount package with dimensions of 3.20 mm length, 1.60 mm width, and 1.4 mm height. The component provides an impedance of 390 Ohms at a test frequency of 100 MHz. It supports a maximum DC current rating of 2 A and has a maximum DC resistance of 50 mOhms. The device operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides high impedance for effective electromagnetic interference filtering in power and signal lines
• Designed for surface-mount assembly using SMD/SMT termination types
• Constructed as a differential mode ferrite chip bead for targeted noise suppression

Applications

• Power line filtering
• Signal line filtering

Procurement Notes

Verify the manufacturer designation, as some listings may display Qnity instead of Laird. Confirm RoHS compliance status through official documentation, as sources vary. Ensure the specific suffix matches the required packaging format, such as reel or cut tape, before ordering. Cross-reference the impedance value of 390 Ohms at 100 MHz to confirm correct part selection.

Selection Notes

Select this component when a 390 Ohm impedance at 100 MHz is required for EMI suppression. The 2 A current rating suits moderate power applications. The 1206 footprint allows for standard surface-mount placement. Verify thermal limits against operating conditions, as the range extends to 125°C.

Part Context

This component belongs to the MI series of ferrite beads from Laird-Signal Integrity Products. It is categorized under ferrites and specifically designed for EMI filtering. The product utilizes a single-line configuration within a standard 1206 metric package size.
