Overview
The Würth Elektronik 742792664 is a surface-mount EMI suppression ferrite bead from the WE-CBF series, housed in a 0603 (1608 metric) package. It exhibits an impedance of 1000 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 300 mA. The component features a maximum DC resistance of 50 mOhms with a 25% impedance tolerance. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification for automotive reliability.
Feature Summary
- Provides effective electromagnetic interference suppression through high impedance characteristics at target frequencies.
- Designed for automated assembly using standard surface-mount technology reflow soldering processes.
- Constructed with reliable nickel-tin electrodes to ensure robust electrical connections.
Applications
- Automotive electronic circuits requiring AEC-Q200 qualified components
- High-frequency signal line filtering on printed circuit boards
- Power supply input/output noise attenuation
Procurement Notes
Verify the specific manufacturer datasheet to confirm exact impedance tolerances and thermal derating curves before finalizing designs. Ensure that the selected packaging format aligns with available automated placement equipment capabilities. Cross-reference the AEC-Q200 certification status directly with the manufacturer's official documentation to validate automotive suitability requirements.
Selection Notes
Select this component when space constraints necessitate a 0603 footprint while maintaining significant current handling capabilities relative to smaller packages. Evaluate the 1000 Ohm impedance profile against the specific noise spectrum requiring attenuation. Confirm that the 300 mA current rating exceeds the maximum operational current of the protected circuit line under all conditions.
Part Context
This part belongs to the WE-CBF family of SMD ferrite beads manufactured by Würth Elektronik. The series offers various impedance values and current ratings across multiple standard package sizes, including 0402, 0805, and 1206. These components are engineered to provide consistent performance in compact electronic assemblies where space efficiency and noise suppression are critical design parameters.
Replacement Considerations
Direct substitutes include other 0603 ferrite beads with comparable 1000 Ohm impedance and 300 mA current ratings. Verify that alternative parts meet the same AEC-Q200 automotive qualification standards if required for the application. Check physical dimensions and terminal configurations to ensure compatibility with existing PCB footprints.
