MI1206K310R-10

Overview

The MI1206K310R-10 is a monolithic ferrite chip bead designed for surface mount applications in the 1206 (3216 metric) package. It provides an impedance of 31 Ohms at 100 MHz with a maximum DC resistance of 45 mOhms and a current rating of 1.5 A. The component operates within a temperature range of -40°C to +125°C, featuring dimensions of 3.2 mm length, 2.5 mm width, and 1.4 mm height.

Feature Summary

• Monolithic construction for differential mode EMI filtering
• High current handling capability up to 1.5 A
• Low DC resistance design for minimal signal loss

Applications

• Power line noise suppression
• Signal line filtering
• General purpose EMI suppression in compact electronics

Procurement Notes

Verify RoHS compliance status through official manufacturer documentation prior to integration, as environmental declarations may vary by production batch or region. Confirm that the specific ordering suffix corresponds to the required packaging format, such as cut tape or reel, to ensure compatibility with automated assembly processes.

Selection Notes

Select this component when a 1206 footprint is required for circuits carrying currents up to 1.5 A. The 31 Ohm impedance at 100 MHz targets specific high-frequency noise profiles. Ensure the low DCR specification aligns with power integrity requirements to prevent excessive voltage drop across the filter.

Part Context

This part belongs to the Laird MI series of ferrite beads, which are engineered for robust performance in space-constrained designs. The series offers various impedance and current ratings within standard industry footprints, providing designers with standardized options for integrating passive filtering into dense PCB layouts.
