Current Rating and Contact Finish — Signal-Duty Profile
The 98424-F52-26ULF: The gold flash on the mating interface (contact finish thickness listed as flash) is sufficient for intermittent mating in controlled environments; for high-cycle applications (500+ mates), a thicker gold layer on the mating half is worth confirming.
Surface-Mount Termination and Board Layout
Termination is SMT solder — the header sits flat on the board surface without through-hole stubs. The 0.157" (4.00mm) mating pin length provides enough engagement depth for standard Minitek 2.00mm receptacles. Insulation height of 0.244" (6.20mm) sets the z-height budget above the board; plan the enclosure clearance accordingly.
