All 331 specifications, noise countermeasures for power conversion devices such as high voltage xEV and industrial equipment. A simulation that can calculate the maximum attenuation of a 6th-order filter has been released.
At Tokin, we have released the SC-XV coil, which complies with the automotive standard AEC-Q200 for EMC countermeasures in automotive applications, ahead of the industry, with a rated voltage of 1000VAC/DC and a total of 331 specifications. Additionally, we have launched the "SC-XV Series Filter Circuit Attenuation Characteristics Simulation" on our website to assist our customers' designs. In our webinar scheduled for February 22, 2024, we will introduce a simulation method that can calculate the maximum 6th-order filter attenuation. The SCF/SCR/SCT-XV series offers 321 items consisting of four core sizes with outer diameters of 19/25/29/39mm, in two shapes: vertical and horizontal, and combinations of single-phase and three-phase types. The dual-mode coil SCN-XV series includes 10 items in two single-phase types with a core size outer diameter of 35mm and different heights. From this extensive lineup, it is possible to select suitable specifications according to the noise frequencies that need to be suppressed in various applications.

basic information
The SC-XV series allows for the selection of core materials based on the frequency range of the noise that needs to be suppressed for EMC measures. The main features and basic structure are outlined below. <SCF-XV Series> Core Material: Nanocrystal Features: A series that uses nanocrystal material for the core. It supports wideband noise suppression while having high permeability, achieving high inductance and +150°C high heat resistance. <SCR-XV Series> Core Material: Ferrite S15H Features: Utilizes a uniquely developed high-permeability ferrite: S15H core. Suitable for noise suppression in the low-frequency range, achieving high inductance and +120°C compatibility. <SCT-XV Series> Core Material: Ferrite 7HT Features: Uses a uniquely developed ferrite: 7HT core, characterized by high Curie temperature and high Bs (saturation flux density) properties, achieving +150°C high heat resistance. <SCN-XV Series> Core Material: Ferrite 7HT Features: A dual-mode coil that combines two functions of differential mode and common mode noise suppression into one coil, achieving +150°C high heat resistance.
