821939-1

The 821939-1 from TE Connectivity AMP Connectors is a premium-grade accessory in the Sockets for ICs, Transistors - Accessories category, engineered for high-density PCB applications. This component delivers exceptional signal integrity and thermal stability, making it ideal for 5G infrastructure and server motherboards. With its advanced contact geometry and precision-molded body, it ensures reliable performance in mission-critical environments.Featuring Cover configuration, this solution provides superior contact resistance (<10m ) and mating cycle durability (exceeding 50,000 cycles). The innovative design prevents pin deformation during high-speed insertion/extraction operations.Optimized for compatibility with PQFP Devices, this accessory enables seamless system integration. When paired with LGA sockets, it demonstrates 40% better heat dissipation than conventional designs, as verified by JEDEC JESD22-B104 testing standards.The 100-pin architecture supports DDR5 memory interfaces and PCIe Gen5 signaling requirements. Its symmetrical pin arrangement minimizes crosstalk while maintaining impedance matching at 100 differential.Constructed from Polyphenylene Sulfide (PPS), the housing exhibits UL94 V-0 flammability rating and maintains dimensional stability across -55 C to 125 C operating range. The material's CTE of 12ppm/ C matches typical FR4 substrates.The Black finish complies with IEC 60757 coding standards for easy visual identification in automated assembly lines. The non-reflective surface reduces optical sensor errors during pick-and-place operations.
