Chemi-Con SM Amorphous Choke Coils offer low resistance due to the lead wire going through the core. These amorphous choke coils are iron-based that allows stable operation in high-temperature situations. The SM choke coils feature high safety and reliability standards since there are no layer-short circuits, and the magnetic flux leakage is very small. These amorphous choke coils are automotive-grade models and use noise filters for power sources and automotive electrical units.
