742792640

Overview

The Würth Elektronik 742792640 is a surface-mount EMI suppression ferrite bead from the WE-CBF series. It features a 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm height, and 0.8 mm width. The component provides an impedance of 300 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 300 mA and has a maximum DC resistance of 1.2 Ohms. It operates between -55°C and +125°C and holds AEC-Q200 qualification.

Feature Summary

AEC-Q200 qualified for automotive reliability standards
Compact 0603 surface-mount footprint for space-constrained designs
High-temperature operation up to 125°C

Applications

Automotive electronic circuit protection
EMI suppression in high-frequency signal lines
Power supply noise filtering

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 land pattern. Ensure the application environment remains within the specified -55°C to +125°C operating range. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a small SMD form factor is required for EMI filtering in automotive or industrial applications. The 300 mA current rating suits low-power signal lines rather than high-current power rails. Compare the 300 Ohm impedance at 100 MHz against other frequencies to ensure effective noise attenuation at the target interference spectrum.

Part Context

This part belongs to the WE-CBF series of chip ferrite beads manufactured by Würth Elektronik. The series is designed for electromagnetic interference suppression in compact electronic assemblies. The 0603 size offers a balance between performance and board space efficiency compared to larger packages.
