Procurement Notes

Verify the specific part number against official Wurth Elektronik documentation to ensure accuracy. Confirm that the required impedance characteristics and physical dimensions align with the design specifications. Check for compliance with relevant environmental standards such as RoHS before finalizing procurement decisions.

Selection Notes

Select this component when a small form factor ferrite bead is required for high-frequency noise reduction. Ensure the target cable diameter fits within the 4 mm inner diameter constraint. Evaluate the 160 ohm impedance value against the specific noise spectrum requirements of the application to confirm adequate attenuation.

Part Context

This component belongs to the WE-SAFB series, which focuses on small-size EMI suppression solutions. The series offers various impedance values and dimensions to accommodate different cable sizes and noise profiles. It serves as a passive component for mitigating electromagnetic interference in electronic systems.

Replacement Considerations

Consult official Wurth Elektronik resources for verified substitute part numbers within the same series or compatible alternatives. Do not assume interchangeability based solely on similar dimensions; verify electrical parameters and material composition.
