Wurth Elektronik WE-LF Series Common Mode Choke, 700μH Inductance, 4A Maximum DC Current - 74466240007
This common mode choke provides differential-noise suppression in mains and signal lines for non-automotive equipment. It is designed for through-hole mounting and intended to operate across a wide temperature range while meeting recognised European electrical standards. Typical deployment is where EMI attenuation and robust current handling are required in power-conversion and filter networks.
Features and Benefits:
• 700μH inductance reduces common-mode interference in two-line circuits
• ±30% inductance tolerance allows predictable performance variation
• 4A maximum DC current supports moderate power applications
• 27mΩ impedance yields low insertion loss for minimal voltage drop
• 125°C maximum operating temperature permits elevated thermal operation
• ±30% inductance tolerance allows predictable performance variation
• 4A maximum DC current supports moderate power applications
• 27mΩ impedance yields low insertion loss for minimal voltage drop
• 125°C maximum operating temperature permits elevated thermal operation
Applications
• Suitable for EMI suppression in switch-mode power supplies
• Ideal for filtering in industrial control equipment
• Used with mains input stages requiring 250V AC handling
• Can be used for noise reduction on two-line data interfaces

What pin configuration does it provide for PCB assembly?
It uses a four-pin through-hole layout providing two-line common-mode placement with straightforward soldering.
How is long-term exposure to elevated temperatures addressed?
The component is rated to operate up to 125°C which maintains electrical parameters under high-temperature conditions.
What packaging formats are available for handling and storage?
Units are supplied in tray and carton packaging suitable for automated pick-and-place and bulk transport.
Which tests define the component’s inductance measurement conditions?
Inductance is specified at a 10kHz test frequency to reflect performance in typical EMI environments.
What approvals confirm its suitability for regulated applications?
It holds ENEC, VDE, RoHS and REACH approvals indicating conformity with specified European safety and material standards.
