0805RB-221XMRC

Overview

The Coilcraft 0805RB-221XMRC is a wirewound ferrite bead in an 0805 (2012 metric) surface-mount package. It provides 220 Ohms impedance at 100 MHz with a maximum DC resistance of 180 mOhms and a rated current of 1A. The component operates within a temperature range of -40°C to +80°C and supports up to three reflow soldering cycles at +260°C.

Feature Summary

• Wirewound construction for effective AC noise isolation from DC bias or power injection lines
• Designed for baseband RF amplifier applications
• RoHS compliant and halogen-free composition

Applications

• Baseband RF amplifiers
• DC power injection lines
• AC noise isolation circuits

Procurement Notes

Verify the specific suffix XMRC against official Coilcraft documentation to confirm exact impedance tolerance, current rating, and packaging configuration. Ensure compatibility with standard SMD/SMT PCB mounting processes and thermal profiles during assembly.

Selection Notes

Select this component when high-frequency noise suppression is required on DC lines without significant signal attenuation. The 1A current rating suits moderate power applications, while the low DCR minimizes voltage drop. Confirm that the 220 Ohm impedance profile matches the target noise frequency spectrum.

Part Context

This part belongs to the Coilcraft 0805RB series of wirewound ferrite beads. These components are engineered specifically for isolating AC noise from DC bias or DC power injection lines, particularly in baseband RF amplifier environments where signal integrity is critical.

Replacement Considerations

Consult official Coilcraft substitution guides for verified equivalents. Generic replacements may differ in Q-factor, saturation current, or impedance curves.
