0805RB-272XMRC

Overview

The Coilcraft 0805RB-272XMRC is a wirewound ferrite bead designed for high-frequency noise suppression in surface-mount applications. It features an unshielded construction with a ceramic core, housed in a compact 0805 (2012 metric) package measuring 2.03 mm in length, 1.27 mm in width, and 1.65 mm in height. The component exhibits an impedance of 2700 Ohms at 100 MHz and maintains a maximum DC resistance of 0.4 Ohms. It supports a maximum DC current of 1 A and operates reliably within a temperature range of -55°C to +125°C.

Feature Summary

• Wirewound ferrite construction provides effective isolation of AC noise from DC bias or power injection lines
• Unshielded design suitable for baseband RF amplifier applications
• RoHS compliant and halogen-free manufacturing

Applications

• Baseband RF amplifier circuits
• DC power injection line filtering
• AC noise isolation in signal paths

Procurement Notes

Verify the specific suffix XMRC against official Coilcraft documentation to confirm termination and packaging details. Ensure compatibility with RoHS and halogen-free requirements. Confirm availability status through authorized distributors as supply conditions may vary. Cross-reference the full part number to avoid confusion with similar series variants.

Selection Notes

Select this component when high impedance at 100 MHz is required for noise suppression in space-constrained designs. The 0805 footprint allows for dense PCB layouts. Verify that the 1 A current rating meets the circuit's DC bias requirements. Consider the unshielded nature of the device regarding potential electromagnetic interference coupling in sensitive environments.

Part Context

This component belongs to the Coilcraft 0805RB series of wirewound ferrite beads. These parts are engineered specifically for isolating AC noise from DC bias or DC power injection lines in baseband RF amplifier applications. The series offers various impedance values to suit different frequency suppression needs while maintaining a consistent low-profile form factor.

Replacement Considerations

Consult official Coilcraft documentation for confirmed substitute part numbers. Ensure any replacement matches the 0805 footprint, 2700 Ohm impedance at 100 MHz, and 1 A current rating. Verify that alternative components maintain RoHS compliance and similar thermal characteristics.
