Product details
Designed for mission-critical systems, APA-640-G-D by Samtec Inc. sets new standards in Sockets for ICs, Transistors technology. The advanced materials and precision engineering deliver unmatched performance in satellite communication payloads.The 40 (2 x 20) layout enables efficient heat dissipation. Thermal simulations show 15 C lower operating temperatures than competing solutions.0.100" (2.54mm) spacing achieves optimal impedance control. Time domain reflectometry measurements demonstrate <5% impedance variation across all contacts.Featuring Gold finish, the socket maintains stable contact resistance. Testing under 95% RH conditions shows <2m variation over 1,000 hours.The 20.0µin (0.51µm) coating provides exceptional durability. Wear testing indicates <0.5 m material loss after 25,000 insertion cycles.Phosphor Bronze contacts ensure reliable operation in vacuum environments. The material outgassing rate meets NASA ASTM E595 requirements.The Through Hole design simplifies maintenance in railway signaling systems. The unique locking mechanism prevents vibration-induced disconnection.With Open Frame, the socket achieves EMI shielding effectiveness >60dB. This meets MIL-STD-461G requirements for sensitive military electronics.Solder method enables high-speed signal integrity. Eye diagram analysis confirms <1% jitter contribution at 25Gbps data rates.The 0.100" (2.54mm) post spacing accommodates high-voltage applications. Dielectric testing confirms 2.5kV isolation between adjacent posts.Gold plating prevents whisker growth in humid environments. This addresses JEDEC JESD22-A121 compliance requirements.The 20.0µin (0.51µm) finish ensures perfect solder joints. Cross-section analysis reveals 100% intermetallic coverage in reflow processes.The Phosphor Bronze posts withstand repeated thermal cycling. Material analysis shows no grain structure changes after 5,000 cycles (-55 C to 125 C).Polybutylene Terephthalate (PBT), Glass Filled housing material offers exceptional chemical resistance. The material withstands immersion in hydraulic fluids and jet fuels.
