Wurth Elektronik WE-SL2 Series Common Mode Filter, 51μH Inductance, 5.5kΩ Impedance - 744227S

This common mode filter is a surface-mounted choke designed to suppress differential and common-mode interference in automotive and industrial systems. It operates across a wide temperature range and meets automotive quality criteria for use in demanding environments. The component is supplied on tape and reel for automated assembly and is suitable where Compact EMI mitigation is required.

Features and Benefits:

• 51μH inductance reduces unwanted common-mode noise
• 5.5kΩ impedance at test frequency improves EMI attenuation
• ±30% inductance tolerance allows predictable circuit behaviour
• 0.16Ω maximum DC resistance minimises insertion loss
• Rated to 80V choke voltage for moderate-voltage systems

Applications

• Suitable for automotive ECU noise suppression
• Ideal for CAN and LIN bus interference control
• Used with power supply input filtering in vehicles
• Can be used for in-vehicle infotainment EMI reduction

What temperature range can it withstand?

It functions from -40°C up to 125°C for extended automotive operation.

How many lines does the component filter?

It filters two lines using a dual-line common mode arrangement.

What mounting and termination method does it use?

It is designed for surface mounting with SMD termination style for pick-and-place assembly.

What packaging format is provided for production runs?

Components are shipped on tape and reel to support automated placement.

What test frequency is used to specify impedance?

Impedance and related measurements are specified at a 1kHz test frequency.
