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 VRM/VRD controllers.
