High Permeability Ferrite AEC-Q200 Toroidal Coils KEMET High Permeability Ferrite AEC-Q200 Toroidal Coils feature a wide variety of characteristics for automotive and harsh environment industrial applications. These common-mode chokes offer a high rated voltage of up to 1000V AC/DC, UL 94V-0 flame-retardant base and cap, and AEC-Q200 qualification. The SCR-XV coils are designed with proprietary high permeability ferrite S15H cores, the SCT-XV series utilizes ferrite 7HT cores with proprietary high heat resistance and high Bs characteristics, and SCF-XV coils feature a nanocrystalline metal core and are useful in various noise countermeasure fields. The SCN-XV coils, with their unique core structure, offer a dual-mode solution. The hybrid SCN-XV chokes provide the two functions of standard mode countermeasure and common mode noise suppression but with only one coil.
