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
• 4.5A maximum DC current supporting moderate power circuits
