Reduced Footprint SMD Transformers for MIL-STD-1553 Data Bus Applications

Monday, July 28, 2008

Mission Viejo, CA (July 28, 2008) – Holt Integrated Circuits, in partnership with Premier Magnetics Inc., today expanded it’s offering of MIL-STD-1553 interface transformers to include reduced footprint SMD versions, resulting in the smallest and most cost effective solution on the market today.  Interface transformers are a required part of all MIL-STD-1553 data bus installations.  Holt is the exclusive provider of Premier Magnetics complete line of interface transformers used in conjunction with MIL-STD-1553 transceivers for military data bus applications.

The PM-DB2790S, PMDB2791S, PM-DB2795S and PM-DB2798S have a package outline of just 0.40” x 0.40” x 0.185” and provide all combinations of turns ratio necessary for transformer or direct coupled MIL-STD-1553 data bus applications.  The PM-DB2798S is a dual ratio device, combining both PM-DB2791S and PM-DB2795S to allow selection of either transformer coupled or direct coupled turns ratio from the secondary winding.

“Using these transformers in conjunction with Holt’s HI-1573 dual transceiver, the world’s smallest MIL-STD-1553 transceiver solution, provide a much needed reduction in size in space-constrained MIL-STD-1553 data bus applications”, said Anthony Murray, Director of Business Development at Holt.

Samples and datasheets are available on request.
