Wurth Elektronik WE-SL5 Surface Mount Common Mode Line Filter with Ferrite Core 250μH Sectional Winding ±40 % 2A 744272251

Wurth Elektronik 744272251 WE-SL5 Surface Mount Common Mode Line Filter features a 250μH inductance with a ferrite core and sectional winding construction. It is engineered for EMI suppression, effectively limiting high-frequency common-mode and differential noise in compact electronic assemblies. The filter operates reliably across a wide temperature range from -40°C to 125°C, making it suitable for demanding industrial and automotive applications.

This component supports a maximum DC current of 2 amperes and has a low DC resistance of 35 milliohms to minimize insertion loss. Its inductance tolerance of ±40% provides tolerance for varied design margins. The device complies with the automotive standard AEC-Q200, ensuring high reliability in automotive control modules and communication lines.

The compact surface mount design with dimensions 10mm length, 6.5mm height, and 8.7mm depth eases implementation on dense PCB layouts. It is supplied on tape and reel to facilitate high-speed, automated pick-and-place SMT manufacturing processes. The housing material meets UL-94 V-0 flame retardance standards for safety.

Common applications include noise reduction for automotive signal lines, EMI suppression in power-line modules, integration in compact power supplies for conducted emission control, and communication-line filtering in embedded systems. The sectional winding construction and ferrite core provide robust and stable performance under variable operating conditions.
