742792025 Description

Short technical summary and product information.

This is a WE-CBF series SMT EMI suppression ferrite bead from Würth Elektronik, designed for power line filtering. It offers 120Ω impedance at 100MHz (typical) with a maximum impedance of 160Ω at 400MHz.

 

Electrical characteristics include a DC resistance of 20mΩ maximum and two current ratings: 3A at ΔT=20K and 5A at ΔT=40K. The component is rated for operating temperatures from -55°C to 125°C.

 

The ferrite bead is housed in an 0805 (2012 metric) surface mount package with dimensions 2.00mm x 1.20mm x 1.10mm. It is qualified to AEC-Q200 Grade 1, making it suitable for automotive applications. Compliance includes RoHS, REACH, and Halogen Free.

 

Storage conditions recommend <40°C and <75% RH. Moisture sensitivity level is MSL 1 (unlimited). This component should not be used beyond rated current to avoid excessive heat.
