7427923

Overview

The Würth Elektronik 7427923 is a surface-mount EMI suppression ferrite bead from the WE-CBF series, housed in a 1210 (3225 Metric) package. It provides an impedance of 90 ohms at 100 MHz with a rated current of 400 mA and a maximum DC resistance of 0.3 ohms. The component meets AEC-Q200 automotive standards, ensuring reliability for demanding applications.

Feature Summary

• AEC-Q200 qualified for automotive electronic applications
• High attenuation performance at 100 MHz frequency
• Compact 1210 surface-mount footprint

Applications

• Automotive electronics systems
• Signal line EMI suppression
• Power supply noise filtering

Procurement Notes

Verify that the specific part number matches the required impedance and current ratings for your circuit design. Confirm AEC-Q200 qualification status if the application involves automotive environments. Ensure the 1210 package size fits within the available PCB area constraints.

Selection Notes

Select this component when high-frequency noise suppression is critical in space-constrained designs. The 400 mA rating suits low-current signal lines rather than high-power rails. Consider the 0.3 ohm DC resistance impact on voltage drop in sensitive circuits before finalizing the selection.

Part Context

This ferrite bead belongs to the WE-CBF series, designed specifically for electromagnetic interference suppression in compact electronic assemblies. The series offers various impedance values and current ratings to accommodate different filtering requirements across consumer and industrial electronics.
