Overview
The Coilcraft 0805PB-221XMRC is a wirewound ferrite bead in the 0805 (2012 metric) surface-mount package. It provides an impedance of 220 Ohms at 100 MHz with a maximum DC resistance of 30.5 mOhms and a rated current of 3 A. The component operates within a temperature range of -40°C to +80°C and meets AEC-Q200 automotive qualification standards.
Feature Summary
- Wirewound construction for stable high-frequency performance
- Automotive-grade reliability certified under AEC-Q200
- Low DC resistance minimizes power loss in signal lines
Applications
- High-speed signal line filtering
- Automotive electronic circuits
- EMI suppression in compact PCB designs
Procurement Notes
Verify the specific suffix XMRC against official Coilcraft documentation to confirm packaging and material specifications. Ensure the requested quantity matches available reel sizes. Confirm RoHS compliance status directly from the manufacturer's latest datasheet before finalizing procurement orders.
Selection Notes
Select this component when low insertion loss and high current handling are required for single-channel signal integrity. The 0805 footprint suits space-constrained layouts. Verify that the 220 Ohm impedance profile aligns with the target noise frequency spectrum for effective EMI attenuation.
Part Context
This part belongs to the 0805PB series of wirewound ferrite beads designed for robust signal conditioning. The series offers various impedance values tailored for different frequency ranges, maintaining consistent physical dimensions for standardized board placement across multiple design iterations.
Replacement Considerations
Consult official Coilcraft substitution guides for verified equivalents. Generic replacements may not match the wirewound construction or AEC-Q200 certification requirements.
