Overview
The Würth Elektronik 74279262 is a surface-mount EMI suppression ferrite bead from the WE-CBF series. It features a 0603 (1608 metric) package with an impedance of 120 Ohms at 100 MHz and a maximum DC current rating of 500 mA. The component has a maximum DC resistance of 600 mOhms and operates within a temperature range of -55°C to +125°C. It holds AEC-Q200 qualification for automotive reliability.
Feature Summary
- Provides effective electromagnetic interference suppression through high impedance characteristics.
- Designed for direct surface mounting on printed circuit boards.
- Features low DC resistance to minimize signal loss in power lines.
Applications
- Automotive electronics requiring AEC-Q200 compliance
- General-purpose EMI filtering in compact electronic devices
- Power line noise suppression in space-constrained designs
Procurement Notes
Verify the specific manufacturer part number against official Wurth Elektronik documentation to ensure authenticity. Confirm that the AEC-Q200 qualification status matches your project requirements. Check for any recent product change notices or end-of-life announcements directly from the manufacturer before finalizing procurement decisions.
Selection Notes
Select this component when a small 0603 footprint is required for EMI filtering. Ensure the 500 mA current rating meets the circuit's operational needs. Consider the 120 Ohm impedance at 100 MHz for appropriate noise attenuation. Verify compatibility with standard SMT assembly processes for the specified package size.
Part Context
This ferrite bead belongs to the WE-CBF series, which offers various impedance and current ratings in standard SMD packages. The series is designed for efficient EMI suppression in modern electronic applications where space is limited. The 74279262 specifically targets applications needing moderate current handling with compact dimensions.
Replacement Considerations
Consult official Wurth Elektronik catalogs for direct substitutes within the WE-CBF series with similar impedance and current ratings. Cross-reference with other manufacturers' 0603 ferrite beads only if electrical parameters match exactly. Verify package dimensions and terminal configurations before substitution.
