Wurth Elektronik WE-LF Series Common Mode Choke, 1.2 Mh Inductance, 250V AC Choke Voltage - 7446723001
This common mode choke is a two-line EMI suppression component designed for through-hole mounting and intended to reduce interference in AC circuits. It operates across a wide temperature range and is supplied in tray packaging for handling in production environments. The part meets multiple regulatory standards and is rated for moderate current applications.
Features and Benefits:
• ±30% inductance tolerance provides predictable attenuation performance
• 3A maximum DC current enables moderate power line use
• 40mΩ impedance supports effective common-mode suppression
• 0.04 Ω maximum DC resistance minimises insertion loss
• 125°C maximum operating temperature allows high-temperature operation
• 3A maximum DC current enables moderate power line use
• 40mΩ impedance supports effective common-mode suppression
• 0.04 Ω maximum DC resistance minimises insertion loss
• 125°C maximum operating temperature allows high-temperature operation
Applications
• Suitable for mains EMI suppression in consumer equipment
• Ideal for filtering two-conductor power lines
• Used with switch-mode power supplies for noise reduction
• Can be used for industrial control panels requiring high temperature stability
