Compact Common Mode Chokes

Pulse Electronics Compact Common Mode Chokes offer a 25Ω to 2200Ω impedance range, up to ±25% tolerance, and 50VDC rated voltage. These chokes are designed for excellent noise attenuation with compact sizing for use in various applications, such as USB lines for personal computers and peripherals. The wide impedance range is for noise suppression, and these chokes feature excellent solderability. Pulse Electronics Compact Common Mode Chokes have a wide operating temperature range of -40°C to +105°C.
