Wurth Elektronik WE-SL5 HC Series Surface Mount Common Mode Line Filter, 5μH Inductance, 5A Maximum DC Current - 744273501


This surface-mount common mode line filter is a Compact ferrite choke designed to suppress differential noise on paired conductors in high-current PCB assemblies. It operates across a wide temperature range and is supplied in tape-and-reel packaging for automated placement. The device is intended for applications requiring a sectional-wound, low-resistance solution that fits standard SMD assembly processes.

Features and Benefits:


• 5μH inductance reduces common-mode interference for cleaner signals
• 5A maximum DC current enables use in high-current circuits
• 5.5mΩ maximum DC resistance minimises power loss in lines
• Sectional winding lowers imbalance and improves suppression performance
• Rated to 125°C supports elevated operating temperature environments

Applications


• Suitable for EMI suppression in power distribution lines
• Ideal for filtering in DC-DC converter input stages
• Used with high-current bus interfaces on Compact PCBs
• Can be used for common-mode noise control in industrial electronics
• Suitable for automated PCB assembly with tape-and-reel supply

What termination style does it use for PCB mounting?


It uses a surface-mount termination style compatible with SMD soldering processes.

What core material contributes to its filtering behaviour?


The component employs a ferrite core to provide frequency-dependent impedance for noise attenuation.

How many electrical connections are provided and how is the winding arranged?


It has a four-pin configuration and utilises sectional winding construction.

What environmental approvals and material standards apply to the part?


It conforms to RoHS and REACH requirements and aligns with JEDEC JS709B and IEC 61249-2-21 standards.

How is the component packaged for manufacturing and what is its physical profile?


It is supplied in tape-and-reel packaging and measures 9.5mm length, 8.3mm depth, and 5.3mm height.
