Wurth Elektronik 100 mH 400 mA Common Mode Choke 3470 mΩ 250V

This common mode choke is a through-hole electromagnetic component designed to suppress interference between conductors in signal and power circuits. It operates across a wide temperature range and is supplied in tray packaging for orderly handling. The component is suitable for applications requiring modest current capacity and specific inductance characteristics while meeting contemporary material-substance restrictions.

• 100mH inductance reduces differential noise in paired lines
• -30 to +50% inductance tolerance supports broad design margins
• 0.4A maximum DC current prevents overheating under light loads
• 3470mΩ maximum DC resistance minimises voltage drop
• 125°C maximum operating temperature sustains elevated thermal environments

• Suitable for EMI suppression in low-current power rails
• Ideal for filtering in industrial control interfaces
• Used with signal lines requiring common-mode attenuation
• Can be used for noise reduction in instrumentation circuits

It operates between -40°C and 125°C as its minimum and maximum temperatures.

It is provided in trays to facilitate storage and through-hole insertion workflows.

Measurements were conducted at a 10kHz test frequency.

It conforms to RoHS and REACH requirements.
