742792012 Description

Short technical summary and product information.

The Würth Elektronik 742792012 is a surface mount ferrite bead from the WE-CBF series, designed for EMI suppression in signal line applications. It provides a nominal impedance of 33 Ohms at 100 MHz with a tolerance of ±25%, and a maximum impedance of 58 Ohms at 800 MHz.

 

This ferrite bead offers a low DC resistance of 0.008 Ohms, minimizing power losses in high current circuits. It is rated for a maximum current of 4 A at a 40 K temperature rise and 3 A at a 20 K rise, making it suitable for power supply and filtering applications.

 

The component is housed in a compact 0805 (2012 metric) package with surface mount termination. It operates over a wide temperature range from -55°C to 125°C and is AEC-Q200 Grade 1 qualified for automotive applications. Compliance with RoHS, REACH, and halogen-free standards ensures environmental friendliness.

 

Applications include EMI filtering on signal lines, noise suppression in high current DC lines, and use in automotive electronics where reliability is critical.
