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
• 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
• 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?
