50 Ohm SMP Jack with Full Detent – Why the Detent Matters
The SMP-FS-FDPCT: The full detent feature adds a positive mechanical lock beyond the basic SMP push-on engagement — it takes a deliberate pull to release, which makes this a better choice for a panel-mounted jack that sees field handling or a board-edge port in a portable instrument. Rated to 12 GHz, it covers L-band through X-band and the lower half of Ku-band, which is the working range for most radar, satcom, and test-equipment RF chains below the millimetre-wave threshold.
500 Mating Cycles – Gold Plating and Snap-On Wear Life
The 500-cycle rating comes from the gold-over-brass centre contact and the gold-plated brass body — the plating on both halves resists galling and maintains contact resistance through repeated mate/unmate cycles. The snap-on interface wears the detent spring more than the centre pin, so the 500-cycle figure is a practical limit for the retention force, not the electrical contact. In a production-test fixture where the connector sees daily connect-disconnect, this jack will hold up for years; in a permanent install it effectively never wears out.
