74279217

Overview

The Würth Elektronik 74279217 is a surface mount EMI suppression ferrite bead from the WE-CBF series. It features a 1206 [3216 Metric] package and provides an impedance of 1 kOhm at its rated frequency. The component supports a DC current rating of 650 mA and operates within a temperature range of -55°C to +125°C. Designed for single signal line applications, it serves as an effective solution for electromagnetic interference suppression in compact electronic circuits.

Feature Summary

• Surface mount construction for automated assembly
• High impedance value for effective noise attenuation
• Wide operating temperature range for reliability

Applications

• Single signal line EMI suppression
• Data line filtering
• General purpose noise reduction in compact electronics

Procurement Notes

Verify availability status carefully as this specific part number is scheduled for obsolescence and has been discontinued by the manufacturer. Confirm that any proposed substitute components meet all original electrical specifications, including impedance, current rating, and package dimensions, before finalizing procurement plans.

Selection Notes

Select alternative components from the same manufacturer or compatible suppliers that match the 1206 footprint and 1 kOhm impedance requirement. Ensure the replacement maintains the 650 mA DC current handling capability and operates reliably across the required -55°C to +125°C temperature range to preserve circuit integrity.

Part Context

This component belongs to the WE-CBF series of surface mount ferrite beads. These devices are engineered for high-frequency noise suppression in space-constrained designs. The 1206 package size offers a balance between performance and board real estate efficiency for modern electronic assemblies.

Replacement Considerations

Available substitutes include part number 782763102. Verify that the substitute matches the 1206 package, 1 kOhm impedance, and 650 mA current rating.
