This member carries a limited detent feature — the retention force is lower than a full-detent SMP, making it easier to mate and unmate in applications with frequent connect/disconnect cycles. The gold-plated brass body and gold-plated centre contact provide corrosion resistance and maintain low contact resistance across the rated 500 mating cycles. ## What the 18 GHz and 50 Ohm Ratings Mean for Signal Integrity The 18 GHz maximum frequency and 50 Ohm characteristic impedance define the usable bandwidth and the impedance environment this connector is designed for. At 18 GHz, the wavelength in the connector is short enough that impedance discontinuities cause measurable reflections — the SMP interface is engineered to keep VSWR low across the band. The 50 Ohm impedance must match the PCB trace impedance (typically a grounded coplanar waveguide or microstrip) and the cable impedance for a clean signal path. The limited detent feature reduces the axial force during mating, which helps maintain consistent centre contact compression and repeatable RF performance over the 500-cycle life. The LCP dielectric material maintains stable electrical properties across this range.","metaTitle":"SMP-MSLD-PCS-5T SMP Jack, Gold, 50 Ohm, 18 GHz, SMT","metaDescription":"SMP-MSLD-PCS-5T SMP jack, male pin, 50 Ohm, 18 GHz max, gold body, SMT, snap-on, 500 cycles.
