SMB Jack, 50 Ohm, Through-Hole — 5221111-1
Gold plating on the centre contact handles 500 mating cycles without degradation — suited for test equipment, instrumentation, or any application where the connector is regularly mated and unmated during service.
RF Performance at 4 GHz
Rated to 4 GHz maximum frequency with a 0.3 dB insertion loss, this SMB jack delivers clean signal transmission through the snap-on interface.
Obsolete — Sourcing Reality
If the design can accept a parametric alternative, a 50 Ohm SMB jack from the same class with matching through-hole footprint and 4 GHz bandwidth would be the starting point, but no pin-compatible drop-in is documented.
The snap-on fastening type provides quick connect/disconnect without tools, and the 500-cycle rating indicates the retention spring will hold through repeated use. Mates with any standard SMB female jack that accepts a male pin centre contact — confirm the interface dimensions from the SMB standard before committing.
