Product details
Molex's 1731120821 sets new benchmarks in D-Sub, D-Shaped Connectors - Contacts performance, developed for next-generation 5G infrastructure. These high-speed contacts feature innovative signal integrity enhancements that push the boundaries of RF connectivity.Specialized for Coaxial transmission, the contacts maintain 1.5:1 VSWR up to 6GHz. Compared to conventional designs, they reduce crosstalk by 18dB in adjacent channel configurations.The Female Socket implementation utilizes tuned impedance matching for millimeter-wave applications. Proprietary geometry minimizes skin effect losses above 10GHz.Precision Machined technology ensures consistent RF performance across production batches. Each contact undergoes 100% automated optical inspection for dimensional compliance.Solder, PCB options provide flexibility for mmWave PCB designs. The solder cup variant demonstrates 0.1dB insertion loss advantage at 28GHz in controlled impedance environments.Selected Copper Alloy composition delivers optimal high-frequency performance. Material properties are characterized up to 40GHz using TRL calibration standards.The Gold surface treatment achieves <0.5 in roughness for consistent RF performance. Electroless deposition process ensures uniform coating in high-aspect-ratio geometries.With 8.00µin (0.203µm) Inner, 8.00µin (0.203µm) Outer deposition, the contacts maintain stable contact resistance through thermal cycling (-55 C to +125 C). The finish withstands 100+ reflow cycles at 260 C peak temperature.Gold, Tin plating provides excellent solderability for high-frequency PCB materials. The finish composition is optimized for low-PIM applications (<-160dBc).Precision-controlled 8.00µin (0.203µm) Inner, 200.0µin (5.08µm) Outer ensures reliable connections in vibration-prone environments. Vibration testing per MIL-STD-202G Method 204 demonstrates zero failures at 20G RMS.
