Wurth Elektronik WE-CMB HC Series Common Mode Choke, 10mH Inductance, 230V Choke Voltage - 744822110
This common mode choke is designed to reduce electromagnetic interference in mains and signal lines while operating across standard mains voltages. It is a radial, PCB-mounted component supplied with solder-pad terminations and intended for general electronic assemblies rather than automotive use. The component functions within a wide temperature range and meets multiple international standards for materials and safety.
Features and Benefits:
• 10mH inductance delivers effective EMI suppression
• ±30% tolerance allows predictable performance margin
• 1A maximum DC current supports low-power applications
• 360mΩ maximum DCR minimises series resistance losses
• 10kHz test frequency verifies inductive behaviour under conditions
• ±30% tolerance allows predictable performance margin
• 1A maximum DC current supports low-power applications
• 360mΩ maximum DCR minimises series resistance losses
• 10kHz test frequency verifies inductive behaviour under conditions
Applications
• Suitable for mains EMI filtering in power supplies
• Used with signal lines to reduce common-mode noise
• Ideal for low-current industrial control electronics
• Can be used for equipment requiring regulatory approvals
