Typical applications: • Propulsion Control • Precision Guiding Systems • Data Management 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. • Extreme resistance to impact, shock, and vibration • High reliability for space and mission critical applications • Miniature in size and minimalistic design Contact Pico for part number of available options: • Screening and qualification criteria to flight standard • Fully RoHS compliant or with exemption 7(a) • Modifications to mechanical design and electrical characteristics • Custom new design and parameters
