Product details
TE Connectivity AMP Connectors's 821949-4 sets new benchmarks for Sockets for ICs, Transistors components in renewable energy systems. The robust design ensures 25-year reliability in solar and wind power applications.The QFP architecture provides lightning surge protection. Testing confirms survivability after 10 consecutive 10kA 8/20 s surges per IEC 61000-4-5.With 100 (4 x 25), the socket enables high-current power conversion. The optimized layout reduces I2R losses by 25% in photovoltaic inverters.0.050" (1.27mm) spacing prevents partial discharge in high-voltage applications. Testing shows no PD activity below 2.5kV in humid conditions.Featuring Tin-Lead finish, the socket resists sulfur corrosion. Testing in H2S environments shows no degradation after 1000 hours.The 200.0µin (5.08µm) coating withstands UV degradation. Accelerated weathering tests predict 25-year performance in direct sunlight.Constructed with Phosphor Bronze, the socket handles thermal cycling. Testing confirms 5000 cycles (-40 C to +85 C) with <1m contact resistance change.The Through Hole design resists wind-induced vibration. Testing confirms no loosening after 10^7 cycles at 0.5mm amplitude.Incorporating Closed Frame, the socket prevents PID (Potential Induced Degradation). Testing shows <1% power loss in 1000V biased damp heat conditions.Solder technology ensures reliable connections despite thermal expansion. Testing confirms <0.1mm movement during 100 C temperature swings.The 0.050" (1.27mm) spacing accommodates heavy busbar connections. Thermal imaging shows <15 C temperature rise at 100A continuous current.Tin-Lead plating prevents fretting in vibrating environments. Testing shows <2m change after 10^8 micro-motions.The 200.0µin (5.08µm) finish ensures reliable connections despite thermal cycling. Testing shows no degradation after 1000 -40 C/+105 C cycles.The Phosphor Bronze posts resist stress relaxation. Testing confirms <3% contact force loss after 25 years at 70 C.Liquid Crystal Polymer (LCP) housing material provides tracking resistance. The material achieves CTI 600 for high-pollution environments.
