ECMT1V1717S-470-R is a through-hole common mode choke designed for EMI suppression and noise filtering in industrial and power conversion applications. The device features an open circuit inductance (OCL) of 47 mH with a DC forward current (DCF) of 2.0 mH at +25°C, and a rated current (Imms) of 0.5 A. It provides high voltage isolation with a coil-coil hi-pot rating of 1500 Vac and a coil-core hi-pot rating of 1000 Vac, along with a minimum insulation resistance of 100 MO. The self-resonant frequency (SRF) is 192 kHz minimum, and the component operates reliably across a temperature range of -40°C to +125°C. This robust construction with a closed magnetic path makes it ideal for industrial IoT equipment, motion controls, power supplies, renewable energy inverters, and medical equipment where effective common mode noise attenuation is essential.
