Wurth Elektronik WE-SL2 Series Common Mode Filter, 51μH Inductance, 5.5kΩ Impedance - 744227

This common-mode filter is a surface-mounted EMI suppression component designed for automotive and industrial environments. It operates across a wide temperature range and is intended to reduce conducted interference on differential signal lines while maintaining signal integrity. The component meets automotive-level reliability expectations and is supplied in an assembly-friendly packaging format for volume placement.

Features and Benefits:

• ±30% inductance tolerance provides predictable attenuation performance
• 80V choke voltage enables handling of elevated line potentials
• Low DCR 0.16Ω reduces insertion loss and heat generation
• 1A maximum DC current supports moderate power signal lines
• 125°C maximum operating temperature sustains high-temperature operation

Applications

• Suitable for EMI suppression in vehicle electronics
• Ideal for filtering signal lines in control units
• Used with power rails requiring noise attenuation
• Can be used for interference reduction on sensor interfaces

What termination style does it use?

It employs a surface-mount termination style for automated placement.

How is it packaged for production assembly?

The component is supplied on tape and reel to support pick-and-place processes.

What environmental approvals does it carry?

It complies with REACH and RoHS requirements.

What are the component’s physical envelope dimensions?

The device measures 9.2mm in length, 6mm in depth and 5mm in height.

What test condition defines its impedance rating?

Impedance is specified at a 1kHz test frequency.
