Technical Specifications & Construction Details
Our low-profile SCRW terminal represents the pinnacle of compact electrical connection technology, engineered for space-constrained applications requiring reliable high-current performance. The nickel-plated brass construction with tin contact plating delivers exceptional conductivity while resisting corrosion in demanding environments. With a conservative 15A current rating (20A intermittent), this terminal supports power transmission in tight spaces where conventional connectors would fail. The precision-engineered vertical mounting design (7.87mm length × 3.4mm width) achieves an industry-leading power density of 4.4A/mm², making it ideal for modern high-efficiency electrical systems.
Material Science Advantages
• Contact Material: High-grade brass (CZ121) with 3µm tin plating
• Plating Specifications: 5µm nickel underplate for superior corrosion resistance
• Temperature Range: -55°C to +125°C operational
• Contact Resistance: <2mΩ initial, <5mΩ after 500 cycles
• Mechanical Life: 50+ mating cycles without performance degradation
