Shielded Coupled Inductors MSD1278T

AEC

The MSD1278T series of shielded coupled inductors was

designed specifically for high temperature applications –

up to 125°C ambient.

Q200 125°C

Tight coupling (k ≥ 0.98) and 500 V 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.
