5414168-3 is a 50 Ohm TNC bulkhead jack RF coaxial connector designed for O crimp termination on RG-174, RG-174A, RG-316, RG-188, and RG-188A cables. This commercial-style connector features gold-plated center contacts and nickel-plated body with polymethylpentene dielectric material. The connector has a maximum length dimension of 34.93 mm (1.375 inches) and supports panel mounting with a maximum panel thickness of 6.35 mm (0.250 inches). It provides excellent RF performance with 50 ohm nominal impedance, 500V working voltage, and 5000 megohms insulation resistance. Common applications include RF signal transmission in telecommunications, test equipment, and wireless systems where reliable bulkhead mounting is required.
