904

Keystone Electronics's 904 establishes new benchmarks in Terminals - Solder Lug Connectors for satellite communication systems. This radiation-hardened connector solution withstands 100kRad TID while maintaining signal integrity in GEO orbit conditions. The 904 incorporates proprietary materials that mitigate single-event effects in high-energy particle environments.The Long Stem, Shaped design features triple-redundant contact points, ensuring continuous operation despite micrometeoroid impacts or vibration-induced fretting.Utilizing Lockwasher, Internal Tooth technology, these connectors achieve outgassing rates below 1 10^-6 torr L/sec cm , meeting NASA ASTM E595 standards for space applications.Engineered with 6 Stud configurations, these terminals handle L-band to Ka-band signal transmission with VSWR below 1.2:1 across all frequencies.Precision 0.093" (2.36mm) tolerances accommodate thermal expansion differences between PCB and connector materials in -150 C to +150 C orbital thermal cycles.Flat configuration provides EMI shielding effectiveness exceeding 120dB at 40GHz, crucial for sensitive satellite payload electronics.Optimized 0.875" (22.23mm) dimensions prevent standing wave formation in phased array antenna feed networks, maintaining beamforming accuracy.Brass alloy demonstrates stable contact resistance after 10 years of simulated GEO orbit conditions with 15% contact force degradation.The Tin plating withstands atomic oxygen exposure equivalent to 15 years in low Earth orbit without measurable performance degradation.
