Product details
The 228-7474-55-1902 from 3M delivers laboratory-grade precision for Sockets for ICs, Transistors applications in test and measurement equipment. The ultra-stable design ensures <0.1% measurement uncertainty over 10,000 mating cycles.Featuring SOIC configuration, the socket provides 10^14 insulation resistance. Guarded measurements confirm <1pA leakage current at 1000V for sensitive instrumentation.With 28 (2 x 14), the socket supports high-precision metrology. The symmetrical layout minimizes thermocouple effects to <0.1 V/ C.The Gold finish provides stable thermoelectric properties. Testing confirms <0.5 V contact potential variation over temperature.Constructed with Beryllium Copper, the socket minimizes magnetic interference. Testing shows <0.1 T field distortion at 1mm distance.The Through Hole design prevents microphonic noise. Testing confirms <1 V vibration-induced noise in sensitive amplifier circuits.Incorporating Closed Frame, the socket provides Faraday cage shielding. Testing shows >100dB RF isolation up to 10GHz for precision measurements.Solder technology ensures negligible insertion loss. Network analyzer measurements show <0.01dB loss at 6GHz for RF test applications.Gold plating prevents surface oxidation. XPS analysis shows <1nm oxide growth after 1000 hours in cleanroom environments.The 30.0µin (0.76µm) finish guarantees reproducible connections. Testing shows <0.01% contact resistance variation between mating cycles.The Beryllium Copper posts maintain dimensional stability. Interferometer measurements show <10nm flatness variation over temperature.Polyethersulfone (PES), Glass Filled housing material provides ultra-low outgassing. RGA testing shows <1 10^-9 Torr total mass loss for vacuum applications.Rated for -55°C ~ 150°C, the socket ensures measurement stability. Testing confirms <1ppm/ C thermal EMF variation across the range.
