Overview
The Würth Elektronik part number 742863122 is a WE-CBF HF series surface-mount EMI suppression ferrite bead. It features a 0603 (1608 metric) package with an impedance of 220 Ohms at 100 MHz and a maximum DC current rating of 600 mA. The component exhibits a maximum DC resistance of 250 mOhms and operates within a temperature range of -55°C to +125°C.
Feature Summary
- Provides effective electromagnetic interference suppression for high-frequency signal lines
- Designed for direct surface-mount placement on printed circuit boards
- Constructed from specialized SMD chip bead ferrite material
Applications
- EMI suppression in high-frequency signal circuits
- Noise filtering for portable electronic devices
- Signal line protection in compact consumer electronics
Procurement Notes
Verify the specific impedance value against design requirements, as datasheets may list 22 Ohms or 220 Ohms depending on the exact revision. Confirm the package size is 0603 and the current rating meets the 600 mA requirement. Ensure compatibility with RoHS standards and check for any recent PCN updates regarding packaging or materials before finalizing procurement.
Selection Notes
Select this component when low DC resistance and high-frequency noise attenuation are critical. The 0603 footprint suits space-constrained designs. Evaluate the 600 mA current handling capability against peak load conditions. Consider the operating temperature range up to 125°C for thermal stability in demanding environments.
Part Context
This ferrite bead belongs to the WE-CBF HF series, which focuses on high-frequency performance. It is manufactured by Würth Elektronik GmbH & Co. KG. The series is designed for SMD applications, offering a compact solution for EMI suppression without requiring through-hole mounting techniques.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and impedance characteristics if considering alternative manufacturers' components.
