Designed for wire-to-board power applications where low vertical profile is required, this header features tin-plated brass contacts with up to 8.5A current carrying capacity. The solder tab provides additional board retention strength, while the PCB locator ensures accurate automated SMT placement. The high-temperature LCP housing is compatible with lead-free IR reflow soldering processes.","working_principle":"The 43045-1210 header uses the same Micro-Fit 3.0 contact system as the vertical variants, with dual-beam contacts providing four points of contact per mating interface for reliable electrical connection. The right-angle orientation allows the mating wire housing to exit parallel to the PCB surface, reducing the overall height of the assembly. The solder tab on the bottom of the connector provides additional mechanical retention beyond the SMT solder joints, critical for withstanding mating and unmating forces in right-angle configurations.","pin_description":"
