Coupled Inductors –MSD1260T Forhightemperature
applications
The MSD1260T series of shielded coupled inductors was
designed specifically for high temperature applications –
up to 125°C ambient.
Tight coupling (k ≥ 0.97) and 500 Vrms isolation make them
ideal for use in a variety of circuits including flyback, multi-
output buck, SEPIC and Zeta. These parts provide high
inductance, high efficiency and excellent current handling.
They can also be used as two single inductors connected
in series or parallel or as a common mode choke.
