MSD1278 AEC-Q200 Grade 3 Coupled Inductors

Coilcraft MSD1278 AEC-Q200 Grade 3 Coupled Inductors offer high inductance, high efficiency, and excellent current handling. They are available as two single inductors connected in series or parallel or as a common mode choke. Tight coupling (k ≥ 0.98 MSD1260 and MSD1278 series) (k ≥ 0.97 MSD7342 series) and 500V isolation make them perfect for use in a wide range of circuits including flyback, multioutput buck, SEPIC, and Zeta.
