Overview
The Würth Elektronik 7427927291 is a surface-mount ferrite bead from the WE-CBF series, designed for signal line noise suppression. It features a 0402 (1005 metric) package with an impedance of 600 ohms at 100 MHz. The component supports a maximum current rating of 300 mA and has a maximum DC resistance of 600 milliohms. It operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards.
Feature Summary
- Provides high impedance for effective electromagnetic interference suppression in compact designs
- Automotive qualified under AEC-Q200 standards for reliability
- Utilizes reliable nickel-tin electrodes for soldering compatibility
Applications
- Automotive electronic circuits requiring EMI filtering
- High-frequency signal line noise suppression
- Compact consumer electronics with space constraints
Procurement Notes
Verify the specific impedance value and current rating against the official datasheet before integration. Confirm that the 0402 package dimensions align with the PCB footprint requirements. Ensure the operating temperature range covers the intended environmental conditions. Check for any recent product change notices or obsolescence announcements from the manufacturer.
Selection Notes
Select this component when high attenuation is required in a minimal footprint. The 600-ohm impedance at 100 MHz targets specific noise frequencies. The 300 mA current limit suits low-power signal lines rather than power delivery paths. Consider the AEC-Q200 certification if the application involves automotive systems.
Part Context
This part belongs to the WE-CBF series of chip ferrite beads. The series offers various impedances and package sizes, including 0402, 0603, and 0805. These components are engineered for broadband noise suppression in digital and RF circuits. The 7427927291 specifically addresses the need for high impedance in small form factors.
Replacement Considerations
No public substitute part numbers are confirmed in the provided documentation. Evaluate other WE-CBF variants with similar impedance and package size if availability is an issue.
