It uses a push-pull fastening type and surface-mount termination, making it suitable for parallel PCB connections in space-constrained assemblies. Rated at 2A per contact and 200V, this receptacle handles signal and low-power duty across general-purpose, industrial, and medical applications. ## SMT termination and housing details The surface-mount termination (Solder) allows reflow assembly directly to the PCB, eliminating through-hole soldering.","metaTitle":"55510-146LF Minitek 2.00mm Receptacle, 46-Pos, SMT","metaDescription":"55510-146LF: 2.00mm pitch, 46-position, 2-row SMT receptacle from Minitek series.
