The Würth Elektronik 74269241601 is a surface-mount EMI suppression ferrite bead from the WE-TMSB series. It features a 0402 (1005 metric) package with an impedance of 600 ohms at 100 MHz and a DC resistance of 0.25 ohms. The component supports a nominal DC current of 850 mA and operates within a temperature range of -55°C to +125°C.
Verify the specific package dimensions and electrical ratings against the official datasheet before integration. Confirm compliance with RoHS directives and REACH regulations for your target market. Ensure the selected supplier provides authentic components with traceable documentation to maintain supply chain integrity and product reliability standards.
Select this component when a small footprint is critical for EMI reduction on signal or power lines. The 600-ohm impedance offers significant attenuation for high-frequency noise, while the 850 mA current rating suits moderate load applications. Consider the low DC resistance to minimize voltage drop and power loss in sensitive circuits.
This ferrite bead belongs to the WE-TMSB series, which focuses on miniaturized EMI suppression solutions. The 0402 package allows for high-density PCB mounting, making it ideal for modern portable electronics where space is limited. It complements other passive components by providing targeted noise filtering without increasing board size.
The impedance is 600 ohms at 100 MHz.
The nominal DC current rating is 850 mA.
