Overview
The Würth Elektronik WE-CBF 74279268 is a surface-mount EMI suppression ferrite bead designed for single-signal line applications. It features a 0603 (1608 metric) package with dimensions of 1.60mm length, 0.80mm width, and 1.00mm maximum height. The component provides an impedance of 15 Ohms at 100 MHz and supports a maximum DC current of 500mA. It exhibits a maximum DC resistance of 100 milliohms and operates within a temperature range of -55°C to +125°C. This part is AEC-Q200 qualified.
Feature Summary
- Provides electromagnetic interference suppression for single signal lines
- AEC-Q200 qualified for automotive reliability standards
- Compact 0603 surface-mount footprint for space-constrained designs
Applications
- Automotive electronics systems
- Signal line filtering in compact devices
- EMI suppression in portable electronics
Procurement Notes
Verify the specific impedance tolerance and DC resistance values against the official datasheet before integration. Confirm that the 0603 package dimensions align with your PCB land pattern requirements. Ensure the 500mA current rating meets the operational demands of your circuit design under all expected thermal conditions.
Selection Notes
Select this component when a low-profile, single-line filter is required for high-frequency noise attenuation. The 15 Ohm impedance at 100 MHz targets specific RF interference ranges. Consider the 100 milliohm DC resistance impact on voltage drop if the signal line carries significant continuous current. The AEC-Q200 qualification makes it suitable for automotive environments requiring robust performance.
Part Context
This ferrite bead belongs to the Würth Elektronik WE-CBF series, which offers various impedance and current ratings across multiple standard packages. The 74279268 specifically addresses needs for moderate impedance in small form factors. It complements other WE-CBF parts like the 742792095 or 74279244, which offer higher impedances or different current capabilities for diverse filtering scenarios.
