Overview
The Wurth Elektronik 742792621 is a surface-mount EMI suppression ferrite bead from the WE-CBF series. It features a 0603 (1608 metric) package with an impedance of 140 Ohms at 100 MHz and a maximum DC resistance of 200 mOhms. The component supports a maximum DC current of 550 mA and operates within a temperature range of -55°C to +125°C.
Feature Summary
- High-speed EMI suppression for signal lines
- Compact 0603 surface-mount footprint
- Low DC resistance for minimal signal loss
Applications
- Portable electronic devices
- Data transmission lines
- Power supply filtering
Procurement Notes
Verify the specific impedance tolerance and DC current ratings against the official datasheet before integration. Confirm that the 0603 package dimensions align with the PCB layout constraints. Ensure the operating temperature range meets the environmental requirements of the final assembly.
Selection Notes
Select this component for applications requiring compact EMI filtering on high-speed signals. The low DC resistance helps maintain signal integrity while attenuating high-frequency noise. Consider the 550 mA current rating to ensure the component does not saturate under normal operating conditions.
Part Context
This part belongs to the WE-CBF series, designed for efficient electromagnetic interference suppression in space-constrained environments. The series utilizes advanced ferrite materials to provide effective noise reduction across a broad frequency spectrum, suitable for modern high-density electronics.
