74279274 Description

Short technical summary and product information.

The Würth Elektronik 74279274 is a WE-CBF series SMT EMI suppression ferrite bead. It offers a nominal impedance of 30 Ω at 100 MHz with a tolerance of ±25%, and a typical maximum impedance of 43 Ω at 500 MHz. The component is rated for a maximum DC resistance of 250 mΩ and has two rated current levels: 300 mA for a 20K temperature rise and 1.6 A for a 40K rise.

 

This ferrite bead is qualified to AEC-Q200 Grade 1, making it suitable for automotive applications. It operates over a temperature range of -55°C to +125°C and is housed in a compact 0402 (1005 Metric) surface-mount package with dimensions of 1.00 mm x 0.50 mm x 0.55 mm. The part is compliant with RoHS, REACH, and Halogen Free standards, and has an MSL of Level 1.
