Overview
The MI0805M221R-00 is a monolithic ferrite bead designed for power line filtering in the 0805 (2012 metric) surface-mount package. It provides an impedance of 220 Ohms at 100 MHz with a maximum DC resistance of 50 milliohms and a rated current of 2.5 Amperes. The component operates within a temperature range of -55°C to +125°C. This specific suffix variant is non-RoHS compliant, distinguishing it from the RoHS-compliant MI0805M221R-10 version which shares identical electrical characteristics.
Feature Summary
- Monolithic construction for reliable EMI suppression on power lines
- High current handling capability suitable for dense PCB layouts
- Low DC resistance minimizes voltage drop and power loss
Applications
- Power supply input filtering
- DC-DC converter output stages
- Noise suppression on high-current signal traces
Procurement Notes
Verify compliance requirements carefully as this part is non-RoHS. Confirm availability status as older suffixes may be discontinued. Ensure the ordering suffix matches the exact regulatory needs of the target market. Cross-reference with the -10 suffix if RoHS compliance is mandatory for the final assembly.
Selection Notes
Select this component when a 220 Ohm impedance at 100 MHz is required for power line noise attenuation. The 2.5A rating supports moderate to high current applications. Consider the -10 suffix variant if environmental regulations require RoHS compliance. Verify that the 0805 footprint fits the design constraints.
Part Context
This component belongs to the Laird MI series of ferrite beads, optimized for signal integrity and EMI filtering. The MI series offers various impedance values and current ratings in standard footprints. The MI0805M221R-00 represents the legacy non-RoHS configuration within this product family.
Replacement Considerations
The MI0805M221R-10 is a direct replacement offering identical electrical performance but with RoHS3 compliance. Other manufacturers' 0805 ferrite beads with 220 Ohm @ 100 MHz and >2.5A ratings may serve as alternatives if pin compatibility is verified.
