Amphenol Corporation SMA Connector 132107

The Amphenol RF SMA Jack, part number 99H4988, is a straight connector designed for RF/coaxial applications with a 50-ohm impedance. It is suitable for use with semi-rigid cables, specifically .141" and .085" outer diameters, and offers reliable performance across a frequency range of DC to 18 GHz. The connector features low voltage ratings of 500V peak for RG-58 and 375V peak for RG-174, with a dielectric withstanding voltage of 1000V RMS for the .141" cable group. Constructed from non-magnetic stainless steel or brass, the connector is designed for durability and high mechanical strength. It has a low voltage standing wave ratio (VSWR) of 1.05 + .005f for the .141" semi-rigid cable group, ensuring minimal signal reflection. The contact resistance is low, at 2.0 milliohms for the center and body contacts, and the insulation resistance is rated at 5000 Megohms. The connector is RoHS compliant and features gold-plated contacts for enhanced conductivity. This SMA Jack is ideal for applications requiring robust and reliable RF connections, making it a suitable choice for engineers looking for high-frequency performance in their projects.
