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
• 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
