74279221100 Description

Short technical summary and product information.

The Würth Elektronik 74279221100 is a WE-MPSB series EMI multilayer power suppression bead designed for high-current filtering applications. It offers a nominal impedance of 10 Ω at 100 MHz with a maximum impedance of 41 Ω typical at 2178 MHz. The component is rated for a maximum continuous current of 10.5 A and features a low DC resistance of 3 mOhm maximum (1 mOhm typical), minimizing power loss in high-current paths.

 

This ferrite bead is housed in a standard 1206 (3216 Metric) surface-mount package with dimensions of 3.20 mm x 1.60 mm and a maximum height of 1.30 mm. It operates over a wide temperature range from -55°C to +125°C, making it suitable for demanding environments. The component is AEC-Q200 Grade 1 qualified, ensuring reliability in automotive applications.

 

Designed for use in power supply lines and DC power buses to suppress high-frequency noise and EMI, the WE-MPSB series is optimized for high-current circuits. Its multilayer construction provides effective attenuation across a broad frequency range while maintaining low DC resistance and high current handling capability.
