TT Electronics HA19 EPS Common Mode Chokes

TT Electronics HA19 Electric Power Steering (EPS) Common Mode Chokes are designed specifically for noise suppression applications found in the growth and expansion of new generation vehicles such as electric vehicles (EVs) and plug-in hybrid vehicles (PHVs). The HA19 components offer high efficiency and excellent current handling in a rugged construction. These chokes are mechanically robust and feature low DC resistance and low temperature rise performance. The HA19 series is ideal for high-efficiency electric power steering EMI applications where size and AEC-Q200 certifications are critical.
