Overview
The Würth Elektronik 742792118 is a surface-mount EMI suppression ferrite bead from the WE-CBF series, housed in a 1206 (3216 metric) package. It provides an impedance of 600 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 2500 mA. The component features a maximum DC resistance of 100 mOhms and operates within a temperature range of -55°C to +125°C. It holds AEC-Q200 qualification for automotive reliability.
Feature Summary
- Provides high impedance for effective electromagnetic interference suppression in compact surface-mount designs
- AEC-Q200 qualified for robust performance in demanding automotive electronic environments
- Capable of handling high direct current loads without significant saturation
Applications
- Automotive electronics requiring AEC-Q200 compliance
- High-current signal line filtering
- Power supply output noise suppression
Procurement Notes
Verify the specific impedance tolerance and DC resistance values against the official manufacturer datasheet prior to finalizing procurement. Confirm that the 1206 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 designing circuits that require substantial current handling capability alongside effective high-frequency noise attenuation. The 1206 form factor offers a balance between thermal performance and space efficiency. Consider the low DC resistance to minimize voltage drop and power loss in high-current paths compared to higher-resistance alternatives.
Part Context
This part belongs to the WE-CBF series of surface-mount ferrite beads manufactured by Würth Elektronik. The series is engineered for general-purpose EMI suppression across various industrial and consumer applications. The 742792118 variant specifically targets applications needing higher current ratings than standard small-signal ferrites while maintaining a standardized SMD footprint.
Replacement Considerations
Consult the official Wurth Elektronik cross-reference documentation for verified substitutes. Ensure any replacement matches the 1206 package size, 600 Ohm impedance at 100 MHz, and 2.5A current rating. Verify that alternative components also meet AEC-Q200 standards if used in automotive contexts.
