Overview
The Würth Elektronik 742792605 is a WE-CBF series SMD EMI suppression ferrite bead in a 0603 (1608 metric) package. It provides an impedance of 33 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 2.2 A. The component features a maximum DC resistance of 15 mOhms and operates within a temperature range of -55°C to +125°C.
Feature Summary
- Provides effective electromagnetic interference suppression for high-speed signal lines
- Designed for surface mount assembly on printed circuit boards
- Capable of handling high direct current loads without saturation
Applications
- High-speed data line filtering
- Power supply output decoupling
- General EMI noise reduction in compact electronics
Procurement Notes
Verify the specific impedance value and current rating against the official datasheet before integration, as these parameters are critical for circuit performance. Confirm that the 0603 package dimensions align with the PCB footprint requirements. Ensure the operating temperature range meets the environmental specifications of the final application.
Selection Notes
Select this component when a low-impedance path is required for power lines or high-current signals while maintaining EMI suppression capabilities. The 0603 form factor is suitable for space-constrained designs. Compare the 33 Ohm impedance and 2.2 A current rating against alternative ferrite beads to ensure compatibility with the target signal frequencies and load conditions.
Part Context
This part belongs to the WE-CBF series of surface mount ferrite beads from Würth Elektronik. These components are engineered for general-purpose EMI suppression in consumer and industrial electronics. The series offers various impedance and current ratings across standard packages to support diverse design needs.
Replacement Considerations
Check for updated versions within the WE-CBF series that may offer improved thermal stability or different impedance characteristics. Verify cross-reference availability from authorized distributors to ensure supply chain continuity.
