Wurth Elektronik WE-SL2 Series Common Mode Filter, 250μH Inductance, 1.2A Maximum DC Current - 744224

This common mode filter is a shielded, moulded surface-mount component designed to suppress differential and common-mode interference on signal and power lines in Compact assemblies. It operates across a wide temperature range suitable for demanding environments and incorporates a ferrite multilayer inductor construction with four terminals for straightforward PCB placement and automated assembly.

Features and Benefits:

• 250μH inductance provides effective EMI suppression
• 1.2A maximum DC current supports moderate current rails
• 0.13Ω low DCR reduces insertion loss
• Ferrite core improves high-frequency attenuation
• Meets RoHS and REACH for restricted-substance compliance

Applications

• Suitable for automotive signal-line noise suppression
• Ideal for high-density SMT power filtering
• Used with communication interfaces to reduce EMI
• Can be used for noise control in control modules

What termination style is provided for PCB assembly?

It uses surface-mount terminations compatible with standard SMT soldering processes.

What construction details affect its electrical performance?

The component uses a multilayer inductor layout with a ferrite core and four pins to deliver common-mode attenuation and defined DC handling.

What packaging format aids automated production?

Components are supplied on tape and reel to support pick-and-place and reflow workflows.
