843996-3 is a crimping terminal manufactured by TE Connectivity for solderless wire-to-terminal connections in industrial electrical assemblies. The terminal is designed to be crimped onto stripped wire using a matching crimping tool, forming a homogeneous metal connection without requiring solder, heat, or flux. The product undergoes rigorous testing including vibration testing (16 hours minimum exposure), crimp tensile strength testing to meet MIL-T-7928 requirements, dielectric strength testing for insulation integrity, and voltage drop testing to ensure electrical resistance stability. Proper crimp quality is achieved through correct selection of wire, terminal, and applicator, with specifications including conductor crimp height (CH1), insulation crimp height (CH2), conductor crimp width (CR1), and insulation crimp width (CR2). This terminal is commonly used in industrial systems where reliable, low-cost electrical connections are critical, and performance is ensured only when crimped with tools from the same manufacturer.
