ECMT1V2023S-2R0-R is a through-hole common mode choke designed to reduce conductive EMI emissions in industrial and consumer electronic applications. The device features a closed magnetic path with independent winding sections, delivering 2.0 mH open circuit inductance (minimum) and a maximum DC resistance of 0.08 O at +25°C, with a self-resonant frequency of 976 kHz. It is rated for 250 Vac operation and provides high voltage isolation with 1500 Vac coil-to-coil and 1000 Vac coil-to-core hi-pot ratings, along with 100 MO minimum insulation resistance. The component operates reliably across -40°C to +125°C ambient temperature range and supports an RMS current of 1.5 A. This robust construction makes it ideal for power supplies, motion controls, renewable energy inverters, battery backup systems, and medical equipment where EMI suppression and high isolation are critical.
