The 903-NM415J-51P is an SMB jack PC mount connector designed for RF and microwave applications requiring non-magnetic construction. It features a 50 ohm impedance with a frequency range from DC to 4 GHz and a dielectric withstanding voltage of 1000 VRMS minimum, ensuring reliable signal transmission in demanding environments. The connector is constructed from beryllium copper with gold plating on both the body and contacts, paired with a PTFE natural insulator for excellent electrical performance. It offers mechanical durability rated for 500 cycles minimum and operates reliably across a wide temperature range of -65°C to +165°C. This connector is ideal for precision RF interconnections in test equipment, communication systems, and military applications where non-magnetic properties and high-frequency performance are essential.
