Common Mode Chokes

Eaton Common Mode Chokes feature a closed magnetic path that reduces conductive EMI emissions. These chokes feature robust construction, independent winding sections, and high-voltage isolation. The common mode chokes support inductance ranges from 5.5µH to 60,000µH and current ratings up to 7A, with low DCR for efficient operation. These chokes operate within the -40°C to 125°C (ECMT) and -40°C to 160°C (CMS) temperature ranges and comply with RoHS and halogen-free standards. Typical applications include industrial IoT equipment, power supplies, renewable energy systems, smart meters, medical devices, and consumer electronics.
