742792662

Overview

The Würth Elektronik 742792662 is a surface-mount EMI suppression ferrite bead from the WE-CBF series, housed in an 0603 (1608 metric) package. It provides an impedance of 1000 Ohms at a test frequency of 120 MHz and supports a maximum DC current of 600 mA. The component features a minimum operating temperature of -55°C and a maximum operating temperature of +125°C. It complies with AEC-Q200 automotive standards and RoHS directives.

Feature Summary

• Provides high impedance for effective electromagnetic interference suppression in compact designs
• Automotive-grade reliability certified under AEC-Q200 standards
• Capable of handling specified DC currents within a wide industrial temperature range

Applications

• EMI suppression in automotive electronic circuits
• Signal line filtering in portable digital devices
• Power supply noise reduction in compact electronics

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official manufacturer datasheet prior to ordering. Confirm that the 0603 package dimensions align with the target PCB footprint. Ensure the selected supplier sources directly from authorized channels to guarantee component authenticity and traceability.

Selection Notes

Select this component when space-constrained applications require significant attenuation at 120 MHz. The 600 mA rating suits low-to-medium current signal lines. Verify thermal management requirements given the 125°C upper limit. Compare impedance characteristics against alternative ferrite materials if higher frequency performance is critical.

Part Context

This part belongs to the WE-CBF family of surface-mount ferrite beads designed for EMI/RFI suppression. The series offers various impedance levels and current ratings in standard footprints like 0603 and 0805. These components are engineered for automated assembly and provide reliable noise filtering for sensitive digital and analog circuitry.

Replacement Considerations

Cross-reference with other Wurth Elektronik WE-CBF parts sharing the 0603 footprint and similar 1000 Ohm impedance at 120 MHz. Ensure any substitute matches the 600 mA current rating and AEC-Q200 qualification if automotive use is required.
