Overview

The Wurth Elektronik part number 74279230 is a Surface Mount Device (SMD) EMI suppression ferrite bead belonging to the WE-CBF series. It features a 1210 [3225 Metric] package configuration designed for direct mounting on printed circuit boards. The component provides an impedance of 32 Ohms and supports a current rating of 400 mA. It utilizes specialized SMD chip bead technology to deliver effective anti-EMI properties alongside low DC resistance, ensuring efficient signal integrity in compact electronic assemblies.

Feature Summary

Specialized SMD chip bead construction enabling direct PCB mounting
Effective anti-EMI suppression characteristics
Low DC resistance design

Applications

General EMI suppression on printed circuit boards
Signal line filtering in compact electronics

Procurement Notes

Verify the specific datasheet version when sourcing this component, as manufacturer documentation may be updated. Confirm that the 1210 package dimensions and 400 mA current rating align with your circuit requirements. Ensure compliance with RoHS3 standards if required by your manufacturing specifications. Cross-reference the impedance value at the target frequency to validate performance for your specific application needs.

Selection Notes

Select this component when space constraints necessitate an SMD form factor rather than through-hole or snap-on ferrites. The 1210 package offers a balance between physical size and current handling capability. Consider the 32 Ohm impedance profile for high-frequency noise attenuation. Evaluate the low DC resistance benefit for power-sensitive lines where voltage drop must be minimized.

Part Context

This component is part of Wurth Elektronik's WE-CBF series, which focuses on surface mount EMI suppression solutions. The series is engineered for modern electronics requiring reliable noise filtering in small footprints. The WE-CBF line emphasizes ease of assembly via standard SMD processes while maintaining robust electromagnetic interference reduction capabilities for sensitive digital and analog circuits.
