This unit
The DDC/North Hills DB30010 is a box-type, multi-stub data bus coupler engineered for MIL-STD-1553B applications. It has transformer-coupled stub ports with controlled signal conditioning, droop limiting, and fault protection to maintain signal integrity across distributed avionic and test environments. The coupler's solder-sealed, hot-tinned cold-rolled steel construction delivers superior environmental shielding, EMI rejection, and corrosion resistance across the full military temperature range.
