Description
Pico’s 65000 series is the surface mount version but electrical equivalent to the QPL of data-bus transformers in MIL-PRF-21038/27. This design with gull wing terminals is convenient than the through-hole versions of the MIL-PRF-21038/27 for pick and place manufacturing process on the PCB. These parts are reliable for enabling data transmission and electrical isolation in MIL-STD-1553 compliant systems.
