74279218 Description

Short technical summary and product information.

The 74279218 is a WE-CBF series SMT EMI suppression ferrite bead from Würth Elektronik. It features 600 Ω nominal impedance at 100 MHz (±25% tolerance) with a typical maximum impedance of 700 Ω at 90 MHz. The component is rated for a continuous current of 1.2 A at a 20 K temperature rise and 2 A at 40 K rise, with a maximum DC resistance of 100 mΩ.

 

Designed for high current applications, the ferrite bead is qualified to AEC-Q200 Grade 1, making it suitable for automotive and other high-reliability environments. It operates over a temperature range of -55°C to +125°C and meets RoHS3, REACH, and halogen-free requirements.

 

The part is housed in a standard 1206 (3216 Metric) surface mount package, with dimensions of 3.2 mm x 1.6 mm and a maximum height of 1.3 mm. It is moisture sensitivity level 1 (MSL 1) and can be stored under standard conditions.
