Product details
The 1-1735438-4 from TE Connectivity AMP Connectors delivers aerospace-grade reliability for Memory Connectors - Inline Module Sockets in satellite communications systems. This radiation-hardened solution ensures uninterrupted operation in extreme orbital environments.Space-qualified MiniDIMM design features triple-redundant locking mechanisms that maintain connection integrity during 25G launch vibrations.With 244 gold-plated contacts, the connector achieves <0.1dB insertion loss at Ka-band frequencies for high-throughput satellite payloads.Certified for DDR3 SDRAM modules, the design incorporates charge-dissipative materials that prevent electrostatic discharge in vacuum environments.Meeting MO-244 requirements, the connector passes NASA outgassing tests with <0.1% TML and <0.01% CVCM for long-duration space missions.The Surface Mount, Right Angle configuration enables hermetic sealing capable of maintaining 10-6 atm-cc/sec helium leak rates in GEO satellite applications.Radiation-tolerant Board Guide, Latches include shielding that attenuates single-event effects from cosmic rays up to 100MeV/(mg/cm ).Normal, Standard - Top orientation supports both planar and stacked PCB configurations common in satellite avionics systems.Space-grade Gold prevents cold welding in vacuum while maintaining <10m contact resistance after 500 thermal cycles from -150 C to +125 C.Precision 15.0µin (0.38µm) coating ensures stable performance despite atomic oxygen exposure in LEO environments.
