Overview
The Würth Elektronik WE-CBF 742792601 is a surface-mount EMI suppression ferrite bead in a 0603 (1608 metric) package. It provides an impedance of 30 Ohms at 100 MHz and supports a maximum DC current of 1000 mA. The component features a low DC resistance of 0.03 Ohms and operates within a temperature range of -55°C to +125°C. It is AEC-Q200 qualified for automotive reliability.
Feature Summary
- Provides effective high-frequency noise attenuation with 30 Ohm impedance at 100 MHz
- Supports rated currents up to 1000 mA for power line applications
- AEC-Q200 qualified for automotive electronic environments
- Utilizes reliable Ni-Sn electrodes for soldering compatibility
Applications
- Automotive electronics circuits
- Power line filtering
- EMI suppression in compact SMD designs
Procurement Notes
Verify the specific impedance value and current rating against the official datasheet before integration. Confirm that the 0603 package dimensions align with the PCB footprint requirements. Ensure the operating temperature range meets the environmental specifications of the final assembly.
Selection Notes
Select this component when space constraints require a 0603 footprint but higher current handling than standard signal-line beads. The 1000 mA rating distinguishes it from lower-current variants, making it suitable for power distribution networks where moderate noise suppression is required without excessive voltage drop.
Part Context
This part belongs to the Würth Elektronik WE-CBF series of surface-mount ferrite beads. The series offers various package sizes including 0402, 0603, 0805, and larger formats. These components are designed for EMI/RFI suppression in digital and analog circuits, with many variants holding AEC-Q200 certification for automotive use.
Replacement Considerations
Check for other WE-CBF parts in the 0603 package with similar 30 Ohm impedance and 1A current ratings. Verify that any substitute maintains the same AEC-Q200 qualification if used in automotive applications.
