742792620 Description

Short technical summary and product information.

The Würth Elektronik 742792620 is a WE-CBF series SMT EMI suppression ferrite bead designed for signal line filtering. It offers a nominal impedance of 100 Ω at 100 MHz with a maximum impedance of 125 Ω at 450 MHz. The component is rated for a continuous current of 500 mA at a 20 K temperature rise and up to 1650 mA at 40 K. DC resistance is 150 mΩ maximum.

 

This ferrite bead is housed in a standard 0603 (1608 metric) surface-mount package with dimensions of 1.60 mm x 0.80 mm and a maximum height of 1.00 mm. It operates over a wide temperature range of -55°C to +125°C and is qualified to AEC-Q200 Grade 1, making it suitable for automotive and other harsh environments.

 

The part is RoHS3 compliant, REACH unaffected, halogen free, and has an MSL of 1 (unlimited floor life). It is designed for wide band / high speed applications where EMI suppression is required on signal lines.
