Product details
Harwin Inc.'s H2157-01 represents the next generation of Terminals - PC Pin, Single Post Connectors, optimized for high-speed digital systems requiring uncompromised signal fidelity. This precision-engineered solution delivers exceptional EMI performance and insertion repeatability for 5G infrastructure applications.The PC Pin architecture incorporates advanced stress-relief features that reduce mechanical fatigue in temperature cycling environments.Implementing Single End topology, the design achieves 40% higher retention force compared to industry standards, critical for vibration-prone installations.Precision-machined 0.050" (1.27mm) Dia contacts maintain sub-nanoohm resistance while withstanding 10N insertion forces.The 0.449" (11.40mm) protrusion length is calibrated for optimal solder joint formation in both lead-free and tin-lead processes.Precision-controlled 0.030" (0.76mm) dimension ensures proper solder wicking control in vapor phase reflow systems.With 0.504" (12.80mm) package height, the terminal enables ultra-low profile designs without sacrificing current carrying capacity.The 0.088" (2.24mm) flange profile incorporates anti-rotation features that prevent terminal movement during automated assembly.Tight 0.055" ~ 0.059" (1.40mm ~ 1.50mm) tolerances ensure gas-tight press-fit connections for high-reliability military applications.The Through Hole configuration supports blind mating applications while maintaining perfect coplanarity across the contact array.Swage technology provides cold-weld quality connections without requiring additional flux or cleaning steps.The Non-Insulated design incorporates UL94 V-0 compliant materials for fire safety in power distribution applications.Compatible with 0.063" ~ 0.094" (1.60mm ~ 2.39mm) PCB stacks, the terminal supports high-speed signal integrity requirements up to 40GHz.Selected Brass alloy offers superior stress relaxation characteristics, maintaining contact force over extended service life.Specialized Tin surface treatment reduces fretting corrosion by 80% in high-cycle applications.The 300.0µin (7.62µm) coating thickness is optimized for both conductivity and wear resistance in sliding contact scenarios.
