Wurth Elektronik WE-CMBNC Series Common Mode Choke, 30mH Inductance, 250V AC Choke Voltage - 7448021230
This common-mode choke is a through-hole EMI suppression component designed to reduce differential noise in electronic circuits. It uses a nanocrystalline core and is intended for applications requiring modest current handling and high-temperature resilience, operating across a wide thermal range while meeting several safety and environmental standards.
Features and Benefits:
• 30mH inductance provides strong common-mode attenuation
• Maximum DC current 1.2A supports low-power signal lines
• Maximum DC resistance 280mΩ reduces insertion-loss impact
• Inductance tolerance -30 to +50% allows flexible circuit matching
• Maximum operating temperature 125°C enables high-heat environments
• Maximum DC current 1.2A supports low-power signal lines
• Maximum DC resistance 280mΩ reduces insertion-loss impact
• Inductance tolerance -30 to +50% allows flexible circuit matching
• Maximum operating temperature 125°C enables high-heat environments
Applications
• Suitable for mains filter stages in power supplies
• Ideal for noise suppression in audio equipment
• Used with control boards in industrial electronics
• Can be used for EMI reduction on signal interfaces
