The side-entry design allows mated cables to lie flat against the board — reducing the overall assembly height, improving cable management in tight enclosures, and eliminating the stress concentration that occurs when vertical connectors are used in applications where cables must be bent immediately after the connector.\u003c\/p\u003e\n\n\u003cp\u003eSurface-mount termination eliminates through-hole drilling from the PCB fabrication process, reducing board cost and enabling placement on both sides of the PCB. The SMT footprint is compatible with standard reflow soldering processes, making this connector suitable for automated assembly lines as well as hand-soldering in prototype and low-volume production environments.\u003c\/p\u003e\n\n\u003cp\u003eThe XH 2.54mm pitch is the universal standard for Arduino shields, 3D printer mainboards, LiPo battery management systems, and virtually every hobbyist and light-industrial PCB produced in the last decade. This horizontal SMT variant brings the same proven XH locking geometry and 3A\/250V electrical rating to applications where the standard vertical through-hole connector cannot be used.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnector System:\u003c\/strong\u003e JST XH series, 2.54mm pitch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Style:\u003c\/strong\u003e SMT (Surface Mount Technology), horizontal \/ side-entry\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrientation:\u003c\/strong\u003e Low-profile, cable exits parallel to PCB surface\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 3A per contact\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 250V AC\/DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Material:\u003c\/strong\u003e Copper alloy, tin-plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Material:\u003c\/strong\u003e PA66 (Nylon 66), UL94 V-0 flame retardant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Mechanism:\u003c\/strong\u003e Positive latch lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch:\u003c\/strong\u003e 2.54mm (0.1 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSoldering Method:\u003c\/strong\u003e Reflow or hand soldering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoHS Compliant:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSMT Horizontal vs. Through-Hole Vertical — When to Choose Each\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eChoose SMT Horizontal when:\u003c\/strong\u003e Assembly height is constrained (e.g., slim enclosures, stacked PCB assemblies), cables must route parallel to the board surface, through-hole drilling is not available or desired, or the connector is on the underside of a PCB where vertical connectors would be inaccessible.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eChoose Through-Hole Vertical when:\u003c\/strong\u003e Maximum mechanical retention is required (through-hole pins provide stronger pull-out resistance), the PCB is single-sided, or the application involves frequent mating\/unmating cycles where SMT pad stress is a concern.\u003c\/p\u003e\n\n\u003ch3\u003ePCB Design Considerations\u003c\/h3\u003e\n\u003cp\u003eThe SMT horizontal footprint requires accurate pad placement to ensure proper contact alignment and solder joint quality. Refer to the JST XH series SMT horizontal datasheet for the recommended land pattern, stencil aperture, and solder paste volume. For hand-soldering, use a fine-tip iron at 300–320°C with no-clean flux to avoid housing distortion. Ensure the PCB surface is clean and free of oxidation before soldering to achieve reliable solder joints on all contacts.\u003c\/p\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSlim Enclosure Electronics:\u003c\/strong\u003e Wearable devices, handheld instruments, compact IoT nodes where vertical connector height is unacceptable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStacked PCB Assemblies:\u003c\/strong\u003e Multi-board systems where inter-board clearance is limited\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e3D Printer Electronics:\u003c\/strong\u003e Mainboard connectors in low-profile printer designs, toolhead PCB connections\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArduino \u0026amp; Development Boards:\u003c\/strong\u003e Custom shield designs requiring low-profile connectors, sensor module PCBs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery Management Systems:\u003c\/strong\u003e LiPo BMS boards where cable routing must be parallel to the board surface\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustrial \u0026amp; IoT:\u003c\/strong\u003e Panel-mount PCB assemblies, sensor node boards, compact control electronics\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRobotics:\u003c\/strong\u003e Servo controller boards, motor driver PCBs in space-constrained robot chassis\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eCompatible with all standard JST XH series pre-crimped cables and XH housings at 2.54mm pitch.
