MI0805M221R-10

Overview

The MI0805M221R-10 is a single-line ferrite bead from the Laird MI series, designed for surface mount applications in the 0805 (2012 metric) package. It provides an impedance of 220 Ohms at a test frequency of 100 MHz. The component supports a maximum DC current rating of 2 Amperes and features a maximum DC resistance of 50 milliohms. It operates within a temperature range of -40°C to +125°C and complies with ROHS3 standards.

Feature Summary

• Monolithic construction for effective electromagnetic interference suppression on power lines
• High current handling capability suitable for dense circuit board layouts
• Low DC resistance to minimize signal attenuation and power loss

Applications

• Power line filtering in portable electronic devices
• Noise suppression in high-speed digital circuits
• EMI mitigation in automotive electronics systems

Procurement Notes

Verify the specific suffix designation during procurement to ensure compliance with environmental regulations, as the MI series includes both RoHS-compliant and non-compliant variants. Confirm the manufacturer part number against official datasheets to distinguish between obsolete legacy parts and active production units. Cross-reference distributor catalogs for accurate availability status.

Selection Notes

Select this component when a 220 Ohm impedance at 100 MHz is required for noise suppression in single-line power applications. Ensure the design accommodates the 2A current rating and the physical dimensions of the 0805 package. Verify thermal management requirements given the operating temperature range and power dissipation characteristics under load conditions.

Part Context
