Document 704-1 Coupled Inductors – MSD1278T For high temperature SEPIC applications www.
DataSheet4U.
com The MSD1278T series of coupled inductors was designed for high temperature applications – up to 125°C.
The excellent coupling coefficient (k ≥ 0.
94) makes it ideal for use in SEPIC applications.
In SEPIC topologies, the required inductance for each winding in a coupled inductor is half the value needed for two separate inductors, allowing selection of a part with lower DCR and higher current handling.
These inductors provide high inductance, high efficiency and excellent current handling in a rugged, low cost part.
They are well suited for use as VRM inductors in high-current DC-DC and...
