FMCN1582 is an HN female connector with solder cup terminal designed for 4-hole flange mount applications in RF and microwave systems. The connector operates across a frequency range from DC to 2 GHz with a characteristic impedance of 50 ohms, meeting MIL-STD-348A specifications. It features a gold-plated brass contact with a nickel-plated brass body and PTFE insulation, rated for an operating voltage of 1,900 Vrms AC and an insulation resistance of 5,000 MOhms. The connector has a 0.906-inch hole spacing on the 4-hole flange and operates reliably across a temperature range of -65°C to +165°C. FMCN1582 is ideal for general-purpose test equipment, rack and panel mount applications, and external enclosure connections where robust RF connectivity is required.
