74279205 Description

Short technical summary and product information.

The Würth Elektronik 74279205 is a single-line ferrite bead designed for EMI suppression in signal lines. It provides a nominal impedance of 1 kΩ at 100 MHz, with a typical maximum impedance of 1050 Ω at 150 MHz. The component is rated for a maximum DC resistance of 0.45 Ω and can handle a rated current of 200 mA at a temperature rise of 20 K, or 900 mA at 40 K.

 

This ferrite bead is housed in a compact 0805 (2012 metric) surface-mount package, measuring 2.00 mm by 1.20 mm with a maximum height of 1.10 mm. It operates over a wide temperature range of -55°C to +125°C, making it suitable for demanding environments. The component is qualified to AEC-Q200 Grade 1, indicating suitability for automotive applications.

 

The 74279205 is part of the WE-CBF series from Würth Elektronik, designed for wide-band/high-speed signal filtering. Its high impedance at high frequencies makes it effective for suppressing electromagnetic interference in digital circuits, power lines, and signal lines. The ferrite bead is RoHS compliant and halogen-free, meeting modern environmental standards.
