Overview
The Würth Elektronik part number 742792093 is a Surface Mount Device (SMD) EMI suppression ferrite bead belonging to the WE-CBF series. It features an 0805 package size with dimensions of 2.0 mm length, 1.2 mm width, and 0.9 mm height. The component provides an impedance of 2700 Ohms at a test frequency of 100 MHz. It has a maximum DC current rating of 200 mA and a maximum DC resistance of 600 mOhms. The device operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.
Feature Summary
- Provides high impedance for effective electromagnetic interference suppression in compact surface mount designs
- AEC-Q200 qualified for automotive electronics reliability standards
- Capable of handling rated DC currents while maintaining low DC resistance
Applications
- EMI suppression in automotive electronic circuits
- Signal line filtering in digital devices
- Power supply noise reduction in portable electronics
Procurement Notes
Verify the specific impedance value and current rating against the official datasheet before integration. Confirm that the 0805 package dimensions align with the PCB footprint requirements. Ensure the operating temperature range meets the environmental conditions of the final assembly. Check for RoHS compliance status if required by regulatory standards.
Selection Notes
Select this component when high attenuation is required at 100 MHz for signals carrying low DC current. The 200 mA rating limits its use in high-power applications. Consider the 600 mOhm DC resistance impact on voltage drop. The AEC-Q200 certification makes it suitable for automotive environments where reliability is critical.
Part Context
This ferrite bead is part of the WE-CBF series from Würth Elektronik, designed for SMD applications. The series offers various impedance values and current ratings to suit different EMI suppression needs. The 0805 form factor allows for dense circuit board layouts while providing effective noise filtering capabilities.
Replacement Considerations
Consult the manufacturer's cross-reference guide for verified substitutes. Ensure any replacement matches the 0805 package, 2700 Ohm impedance at 100 MHz, and 200 mA current rating. Verify AEC-Q200 qualification if automotive use is intended.
