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

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

What pin configuration does it use?

It is supplied as a 4-pin through-hole component with solder-pad termination.

What standards does it comply with?

The component carries VDE, RoHS, REACH and ENEC approvals.

What is the operational temperature range?

It operates between -40°C and 125°C.

What packaging formats are available?

It is supplied in tray and carton packaging.

What core material is used and why does it matter?

A nanocrystalline core is used to provide the magnetic properties required for common-mode suppression while maintaining Compact performance.
