Overview
The Würth Elektronik 742792311 is a surface-mount ferrite bead from the WE-CBF series, designed for high-speed EMI suppression. It features a 1210 (3225 metric) package with dimensions of 3.2 mm length and 2.5 mm width. The component exhibits an impedance of 52 ohms at 100 MHz and supports a maximum DC current rating of 3 A. It has a maximum DC resistance of 25 milliohms and operates within a temperature range of -55°C to +125°C. The device is AEC-Q200 qualified.
Feature Summary
- High rated current capability up to 3 A for power line applications
- AEC-Q200 automotive qualification ensuring reliability in harsh environments
- Reliable nickel-tin electrodes suitable for reflow soldering processes
Applications
- Automotive electronics systems requiring EMI filtering
- High-speed data lines needing signal integrity protection
- Power supply input/output stages for noise suppression
Procurement Notes
Verify the specific impedance tolerance and DC resistance values against the official datasheet before integration. Confirm that the 1210 package footprint matches the PCB layout requirements. Ensure the selected supplier provides genuine components with traceable documentation to maintain AEC-Q200 compliance standards.
Selection Notes
Select this component when a compact SMD ferrite bead is required for high-current applications. The 52-ohm impedance at 100 MHz targets common noise frequencies in digital circuits. Consider the low DC resistance to minimize voltage drop across the component in power-sensitive designs.
Part Context
This part belongs to the WE-CBF series of shielded ferrite beads manufactured by Würth Elektronik. The series is engineered for effective electromagnetic interference suppression in space-constrained electronic assemblies. The 1210 form factor balances performance with standard surface-mount compatibility.
Replacement Considerations
Check for direct substitutes within the WE-CBF series offering similar impedance and current ratings. Verify package dimensions and terminal configurations to ensure mechanical compatibility without redesigning the PCB footprint.
