MI0603L221R-11

Overview

The MI0603L221R-11 is a single-line ferrite bead chip from the Laird-Signal Integrity Products MI series, designed for surface mount assembly in the 0603 (1608 metric) package. It provides an impedance of 220 Ohms at 100 MHz with a maximum DC resistance of 50 milliohms and a rated current of 2 Amperes. The component operates within a temperature range of -40°C to 125°C and measures 1.60mm x 0.80mm x 0.80mm.

Feature Summary

• Provides high impedance filtering for power and signal lines
• Supports high current handling up to 2A
• Low DC resistance minimizes power loss
• Compact 0603 surface mount footprint

Applications

• Power line EMI suppression
• Signal line noise filtering
• RF circuit impedance matching

Procurement Notes

Verify RoHS compliance status as documentation indicates potential variations between lead-free and non-compliant versions. Confirm package dimensions and mounting type against schematic requirements. Check manufacturer datasheets for specific thermal and electrical derating curves before finalizing design integration.

Selection Notes

Select this component when a 220 Ohm impedance at 100 MHz is required for 0603 form factor applications. Ensure the 2A current rating meets circuit load demands. Compare DCR specifications against other variants to balance insertion loss and power efficiency requirements for the specific board layout.

Part Context

This part belongs to the MI series of EMI filtering components manufactured by Laird-Signal Integrity Products. It shares the standard 0603 footprint with other series members but differs in impedance and current ratings. It serves as a passive filter element for suppressing electromagnetic interference in compact electronic assemblies.

Replacement Considerations

MI0603L221R-10 is listed as a direct substitute with identical electrical parameters and packaging.
