Wurth Elektronik WE-SL2 Series Common Mode Filter, 500μH Inductance, 3.3kΩ Impedance - 744223

This common-mode filter is a surface-mounted component designed to suppress differential noise in automotive and industrial circuits. It operates across a wide temperature range and is intended for applications requiring adherence to environmental substance regulations and a Compact mounting style. The device is supplied on a reel for automated assembly.

Features and Benefits:

• 500 μH inductance delivers strong common-mode attenuation
• 3.3 kΩ impedance at 1kHz reduces interference at the test frequency
• ±50% inductance tolerance allows flexible design margins
• 0.15 Ω maximum DCR supports low-loss signal paths
• Rated for 1A maximum DC current to handle moderate loads

Applications

• Suitable for suppressing EMI in vehicle electrical systems
• Ideal for use in control modules with limited board space
• Used for noise reduction on data and power lines
• Can be used for retrofit filters in electronic subsystems
• Suitable for automated SMT assembly from tape and reel

What temperature range can it operate within?

It operates from -40°C up to a maximum of 125°C.

How is the component mounted to boards?

It uses surface-mount terminations suitable for SMT placement.

What automotive reliability standard does it meet?

The device conforms to AEC‑Q200 qualification for automotive parts.

What are its electrical voltage and current limits?

The choke is specified for an 80V choke voltage and a maximum 1A DC current.

Which environmental directives cover its substance compliance?

It is compliant with REACH and RoHS requirements.
