VLH252012E4R7M
Inducteur de puissance miniature CMS, de petite taille et de faible profil, sur un noyau de ferrite spécial. Faible résistance en courant continu, capacité de courant élevée, caractéristiques d'impédance élevée, ils sont excellents pour être utilisés comme bobine d'arrêt dans les circuits d'alimentation en courant continu.
