742792621 Description

Short technical summary and product information.

The 742792621 is a high speed ferrite bead from Würth Elektronik's WE-CBF series, designed for EMI suppression in signal line applications. It provides a nominal impedance of 140Ω at 100MHz with ±25% tolerance, and a typical maximum impedance of 430Ω at 550MHz. The DC resistance is 0.2Ω maximum.

 

Rated current is 550mA for a 20K temperature rise and 1250mA for a 40K rise, allowing flexible use depending on thermal constraints. The component operates over a temperature range of -55°C to 125°C and is qualified to AEC-Q200 Grade 1 for automotive applications. It is RoHS3, REACH, and Halogen Free compliant, with MSL level 1.

 

Packaged in the standard 0603 (1608 metric) surface mount footprint, it measures 1.60mm x 0.80mm with a maximum height of 1.00mm. The recommended land pattern is provided in the datasheet. Storage conditions should be below 40°C and 75% RH.
