A threaded SMA might give you 500 too, but the snap-on here saves time on repeated connects — think test-point access or modular RF modules swapped during maintenance. The gold-on-gold contact interface (center contact and body finish both gold) keeps the mating wear from degrading contact resistance across those cycles. ## Temperature Range and Dielectric This makes the 142146-11 a candidate for outdoor radio heads or engine-compartment RF links where the ambient sees both deep cold and waste heat.","metaTitle":"Amphenol RF 142146-11 SMB Jack, Male Pin, Right Angle","metaDescription":"Amphenol RF 142146-11 SMB jack, male pin, right-angle through-hole, 50 Ohm, gold body, 500 mating cycles.
