7427927141

Overview

The Würth Elektronik 7427927141 is a surface-mount EMI suppression ferrite bead from the WE-CBF series, designed for general electronic equipment. It features a compact 0402 (1005 metric) package with dimensions of 1.00mm length and 0.50mm width. The component provides an impedance of 470 Ohms at 100 MHz and has a maximum DC resistance of 450 milliohms. It supports a current rating of 250 mA and operates within a temperature range of -55°C to 125°C.

Feature Summary

• Provides high impedance for effective EMI noise suppression in signal lines
• Compact 0402 surface-mount footprint suitable for space-constrained designs
• Compliant with AEC-Q200 automotive qualification standards

Applications

• General electronic equipment
• Automotive electronics
• Signal line filtering

Procurement Notes

Verify the specific datasheet version when ordering, as manufacturer documentation may be updated. Confirm that the AEC-Q200 qualification status meets your project's reliability requirements. Ensure the 0402 package size aligns with your PCB layout constraints and soldering capabilities before finalizing procurement.

Selection Notes

Select this component for applications requiring significant attenuation at 100 MHz within a minimal footprint. The 250 mA current rating limits its use to low-power signal lines rather than power delivery paths. Consider the 450 milliohm DC resistance impact on voltage drop if used in sensitive circuits.
