0805RB-751XMRC

Overview

The Coilcraft 0805RB-751XMRC is a wirewound ferrite bead designed for high-frequency noise suppression in surface-mount applications. It operates within a temperature range of -55°C to +125°C and features a compact 0805 (2012 metric) package with dimensions of 2.03 mm length, 1.27 mm width, and 0.93 mm height. The component provides an impedance of 750 Ohms at 100 MHz and supports a maximum DC current of 1.6 A with a maximum DC resistance of 0.14 Ohms. It is RoHS compliant and halogen-free.

Feature Summary

• Wirewound construction for robust high-current handling capabilities
• Low profile design suitable for space-constrained PCB layouts
• Halogen-free composition meeting environmental compliance standards

Applications

• High-speed data line filtering
• Power supply output decoupling
• RF interference suppression in portable electronics

Procurement Notes

Verify the specific suffix XMRC against official Coilcraft documentation to confirm halogen-free status and tape-and-reel packaging configuration. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity before procurement.

Selection Notes

Select this component when high current capacity is required alongside significant high-frequency attenuation. The wirewound architecture offers superior performance compared to standard chip beads for currents exceeding typical limits. Evaluate the 0805 footprint constraints against board density requirements. Confirm that the 1.6 A saturation current aligns with peak operational loads to prevent performance degradation.

Part Context

This component belongs to the Coilcraft 0805RB series of wirewound ferrite beads. The series is engineered for general-purpose EMI suppression in compact electronic devices. The 0805 form factor allows for automated surface-mount assembly processes. It serves as a critical passive element for maintaining signal integrity in noisy environments.

Replacement Considerations

Direct substitutes include other 0805 wirewound ferrite beads with matching 750 Ohm impedance and 1.6 A current ratings. Verify physical dimensions and terminal configurations to ensure compatibility with existing footprints.
