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
• 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
