74279266 Description

Short technical summary and product information.

The 74279266 is a surface mount ferrite bead from Würth Elektronik's WE-CBF series. It offers a nominal impedance of 1 kΩ at 100 MHz with ±25% tolerance, and a typical maximum impedance of 1350 Ω at 140 MHz. This single-line signal line filter is designed for EMI suppression in high-speed circuits.

 

With a maximum DC resistance of 0.6 Ω, it can handle rated currents up to 200 mA (ΔT=20K) and 650 mA (ΔT=40K). The component is qualified to AEC-Q200 Grade 1, making it suitable for automotive environments. It operates over a temperature range of -55°C to +125°C.

 

Housed in a compact 0603 (1608 metric) package measuring 1.60mm x 0.80mm x 1.00mm, it is designed for surface mount assembly. The ferrite bead is RoHS3 compliant, REACH unaffected, halogen free, and has MSL 1 (unlimited) moisture sensitivity.
