Product details
The 75403-003LF from Amphenol ICC (FCI) is a high-performance Terminals - PC Pin, Single Post Connectors engineered for precision signal transmission in mission-critical applications. With advanced contact technology and robust construction, this terminal ensures reliable connectivity in harsh environments while maintaining exceptional signal integrity.Designed with Single Post configuration, this terminal provides versatile mounting options for diverse PCB layouts, ensuring optimal current carrying capacity and mechanical stability.Featuring Pin Retention architecture, the connector delivers superior vibration resistance compared to conventional designs, making it ideal for automotive and aerospace applications.The 0.025" (0.64mm) Square pin diameter achieves perfect balance between current density and insertion force, minimizing contact resistance while preventing PCB damage during assembly.The 0.025" (0.64mm) Square sub-flange geometry prevents solder bridging while ensuring proper capillary action during wave soldering.The compact 0.460" (11.68mm) profile allows space-efficient integration without compromising mechanical strength, particularly valuable in miniaturized IoT devices.The 0.032" ~ 0.034" (0.81mm ~ 0.86mm) tolerance ensures secure press-fit installation while accommodating standard PCB fabrication variances.Supporting Through Hole methodology, this solution offers flexibility for both prototype development and volume production environments.Utilizing Solder technology, the connection maintains <5m contact resistance even after 500+ mating cycles, exceeding MIL-STD-1344 requirements.Non-Insulated design prevents accidental short circuits in high-vibration applications without requiring additional sleeving.Compatible with 0.062" ~ 0.125" (1.57mm ~ 3.18mm) substrates, the terminal accommodates both standard and high-reliability multilayer PCB constructions.The Phosphor Bronze composition delivers excellent spring properties and corrosion resistance, crucial for industrial automation systems.Gold plating provides exceptional wear characteristics, maintaining stable contact impedance in humid environments.Precisely controlled 50.0µin (1.27µm) coating guarantees consistent performance across temperature fluctuations from -55 C to +125 C.
