74279216

Overview

The Würth Elektronik 74279216 is a single-line ferrite bead in the WE-CBF series, designed for surface mount assembly in a 1206 (3216 metric) package. It provides an impedance of 1.2 kOhms at 100 MHz with a maximum DC resistance of 500 milliohms and a rated current of 200mA. The component operates within a temperature range of -55°C to 125°C and has a maximum height of 1.30mm.

Feature Summary

• Provides effective electromagnetic interference suppression for high-speed data lines
• Supports compact surface mount integration in small form factor designs

Applications

• High speed USB 2.0 signal line filtering
• IEEE 1394 interface protection
• LVDS signal integrity enhancement

Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging format matches production requirements. Confirm that the 1206 footprint dimensions align with the PCB layout. Check RoHS compliance status and moisture sensitivity level before storage and reflow soldering processes.

Selection Notes

Select this component when designing circuits requiring EMI suppression for high-speed digital interfaces. Ensure the 200mA current rating exceeds the maximum operating current of the protected line. Verify that the 1.2 kOhm impedance value effectively attenuates noise at the target frequency without degrading signal integrity.

Part Context

This part belongs to the WE-CBF series of surface mount ferrite beads from Würth Elektronik. These components are engineered for general EMI suppression applications where space constraints require a compact 1206 package profile while maintaining reliable performance across industrial temperature ranges.

Replacement Considerations

No public confirmed substitute part numbers are available.
