The package includes the connector and one lockwasher, so you have the hardware to secure it against vibration in a single order line. The nickel-plated brass body gives a corrosion-resistant ground path, and the silver housing colour is standard for QMA hardware. ## Temperature Range and Operating Environment Rated from -55°C to 100°C, this jack lives comfortably in outdoor telecom cabinets, unheated industrial enclosures, and vehicle-mounted RF decks. The PTFE dielectric doesn't shift permittivity with temperature the way a nylon or polypropylene dielectric would, so the 50 Ohm impedance holds across the band. The 480 V voltage rating is more than adequate for the signal levels typical on a QMA line — the real limit is the power handling at 6 GHz, which drops with frequency per the manufacturer's derating.","metaTitle":"930-193J-51S QMA Jack, 50 Ohm, 6 GHz, Bulkhead Mount","metaDescription":"930-193J-51S QMA jack, female socket, 50 Ohm impedance, DC to 6 GHz.
