133-3711-301 is a surface-mount RF connector designed for high-frequency signal transmission and reception. The connector features a brass body with gold plating, beryllium copper contacts with gold plating, and a Teflon insulator, providing excellent electrical conductivity and environmental resistance. Key electrical specifications include a contact resistance of 5 milliohm maximum initially and 8 milliohm maximum after environmental testing for the center contact, with RF high potential withstanding voltage of 600 VRMS at 4 and 7 MHz. Mechanically, the connector exhibits an engagement force of 5.6 lbs maximum and a disengagement force range of 1.0 to 8.0 lbs, with a durability rating of 500 cycles minimum. The connector operates reliably across a temperature range of -65°C to +165°C and meets or exceeds ML-C-39012 standards for thermal shock, corrosion, shock, vibration, and moisture resistance. This connector is ideal for aerospace, military, and telecommunications applications requiring robust RF connectivity with high reliability and environmental durability.
