MI0603K181R-10

Overview

The MI0603K181R-10 is a single-line ferrite chip bead from the Laird MI series, designed for surface-mount assembly in the 0603 (1608 metric) package. It provides an impedance of 180 Ohms at 100 MHz with a maximum DC resistance of 90 mOhms and a rated current capacity of 2 Amperes. The component operates within a temperature range of -40°C to +125°C and measures 1.6 mm in length, 0.5 mm in width, and 0.5 mm in height.

Feature Summary

• Monolithic construction for broadband high-frequency noise suppression on power and signal lines
• Low DC resistance design to minimize voltage drop and power loss in high-current applications
• Compact 0603 footprint optimized for dense surface-mount PCB layouts

Applications

• High-speed digital signal line filtering
• Power supply rail noise attenuation
• RF interference suppression in compact electronic modules

Procurement Notes

Verify the manufacturer designation carefully, as some listings may incorrectly identify Qnity as the producer instead of Laird-Signal Integrity Products. Confirm RoHS compliance status through official datasheets, as documentation varies across distribution channels. Ensure the specific suffix matches the required impedance and current ratings for your circuit design.

Selection Notes

Select this component when a 0603 footprint is required with 180 Ohms impedance at 100 MHz. The 2A current rating supports moderate power delivery while maintaining effective EMI filtering. Verify that the 90 mOhm DC resistance meets the thermal and efficiency constraints of the target application circuit.

Part Context

This part belongs to the Laird MI series of ferrite beads, which are engineered for electromagnetic interference suppression in consumer electronics and industrial equipment. The series offers various impedance values and current ratings across standard SMD packages to support diverse signal integrity requirements.
