Overview
The Würth Elektronik 742792005 is a single-line surface-mount EMI suppression ferrite bead from the WE-CBF series. It features an 0805 (2012 metric) package with dimensions of 2.0mm x 1.2mm and a maximum height of 0.9mm. The component provides an impedance of 5 ohms at 100 MHz and supports a maximum DC current rating of 700 mA. Its maximum DC resistance is specified at 0.07 ohms. The device operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards.
Feature Summary
- Provides electromagnetic interference suppression through high-frequency impedance characteristics
- Constructed using a multi-layer ceramic structure for robust signal line filtering
- Qualified for automotive applications under AEC-Q200 reliability standards
- Designed for surface mount assembly in compact electronic circuits
Applications
- Automotive electronics signal line filtering
- General purpose EMI suppression in consumer devices
- Data line protection in portable equipment
Procurement Notes
Verify the specific impedance tolerance and DC resistance values against the official manufacturer datasheet prior to integration, as these parameters are critical for circuit performance. Confirm that the 0805 footprint matches the design layout requirements. Ensure the selected variant aligns with the required current handling capabilities for the target application environment.
Selection Notes
Select this component when low impedance at DC is required alongside moderate attenuation at 100 MHz. The 700 mA current rating makes it suitable for power-sensitive signal lines where minimal voltage drop is necessary. Consider the 0805 package size for space-constrained designs requiring standard SMT processing compatibility.
Part Context
This part belongs to the WE-CBF series of SMD EMI suppression ferrite beads manufactured by Würth Elektronik. The series offers various impedance and current ratings in standardized packages to support diverse filtering needs across industrial and automotive sectors.
Replacement Considerations
Consult the official Würth Elektronik cross-reference documentation for verified substitutes. Ensure any replacement maintains the 0805 footprint, 700 mA current rating, and 5 ohm impedance specification.
