Wurth Elektronik WE-CMBNC Series Common Mode Choke, 3mH Inductance, 250V AC Choke Voltage - 7448024503


This common mode choke is a through-hole EMI suppression component designed to reduce differential noise in mains and signal lines. It employs a nanocrystalline core to provide stable inductive behaviour across typical test conditions and is suited to assemblies where higher operating temperatures and moderate DC currents are required. The part is supplied in tray packaging with solder-pad terminations for straightforward manual or wave solder processes.

Features and Benefits:


• 3mH inductance delivering effective common-mode attenuation
• 4.5A maximum DC current supporting moderate power circuits
• 22mΩ low DCR reducing insertion losses
• -40°C to 125°C operating range enabling high-temperature applications
• RoHS VDE ENEC REACH approvals ensuring regulatory conformity

Applications


• Suitable for mains EMI suppression in power supplies
• Ideal for filtering in industrial control equipment
• Used with signal lines requiring common-mode noise reduction
• Can be used for retrofit EMI mitigation on assemblies
• Appropriate for consumer electronics with Compact through-hole layouts

What termination style is provided for soldering?


It has solder-pad terminations compatible with manual and wave solder techniques.

What core material affects magnetic performance?


The component uses a nanocrystalline core to influence inductance stability.

How is inductance accuracy specified?


Inductance tolerance is given as -30 to +50% for design margin considerations.

What test conditions are referenced for frequency response?


A test frequency of 10kHz is specified for characteristic measurement.
