MSD1260T

Document 703-1 Coupled Inductors – MSD1260T For high temperature applications www.DataSheet4U.com The MSD1260T series of shielded coupled inductors was designed specifically 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 parts 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 highcurrent DC-DC and VRM/VRD controllers. They can also be used as two single inductors connected in series or parallel, or as 1 : 1 transformers. 0.484 max 12,3 D1 + L1 C1 Dot indicates pin1 Dash number Internal code + + VOUT 0.484 max 12,3 123 X VIN Q1 L2 C2 Load – – Typical SEPIC schematic 0.236 ±0.008 6,0 ±0,2 Refer to Application Note, Document 639, “Selecting Coupled Inductors for SEPIC Applications” Recommended Land Pattern 0.197 5,0 0.138 3,5 0.157 4,0 2 3 1 4 0.217 5,5 0.197 5,0 3 2 4 1 0.177 4,5 0.059 1,5 0.079 2,0 Dimensions are in inches mm 1 L1 3 2 L2 4 Core material Ferrite Terminations RoHS compliant matte tin over nickel over phos bronze.
