Within this product portfolio, female headers play an important role in board-to-board connections, providing a stable interface for signal and power transmission. The Kinghelm KH-2FH-2X8P-H4.3-SMT is a dual-row surface-mount female header designed for compact PCB layouts where connection density and installation efficiency are key considerations.

This model features a 2.00 mm pitch with a 2×8 pin configuration, offering a total of 16 positions. Such a layout allows designers to integrate multiple signal paths within a limited board area, helping to keep routing organized and reducing layout complexity. The consistent 2.00 mm row spacing and pin pitch also make it easy to match with compatible pin headers during the design phase.

In terms of mounting structure, the KH-2FH-2X8P-H4.3-SMT adopts a vertical surface-mount (SMD) configuration, suitable for standard automated SMT assembly processes. The top-entry socket orientation supports vertical board stacking and modular designs, which are commonly used in control boards, expansion modules, and multi-layer electronic assemblies. The square-hole contact structure contributes to stable mechanical engagement during mating. With an insulator height of 4.3 mm, the connector maintains a balanced profile that fits well within height-restricted enclosures.

From an electrical performance perspective, the connector is rated for a current of 1.5 A per contact, making it suitable for signal transmission and low-power supply connections. The maximum contact resistance is 20 mΩ, helping to limit conduction losses at the contact interface. An insulation resistance of at least 1000 MΩ and a withstanding voltage of AC 500 V support stable operation under typical electronic working conditions.

Environmental adaptability is another consideration in connector selection. The KH-2FH-2X8P-H4.3-SMT operates within a temperature range of –40 °C to +105 °C, allowing it to be used in a variety of equipment environments, including industrial and enclosed electronic systems. The product is supplied in tube packaging, which is compatible with automated pick-and-place equipment and supports efficient mass production and inventory handling.

In practical applications, this female header is suitable for use in communication control boards, industrial automation modules, instrumentation, power management boards, and selected consumer electronics. It serves as a board-to-board interconnection component where dual-row, surface-mount installation and compact structure are required.

Supported by its modern manufacturing base in Luzhai, Guangxi, and flexible intelligent production lines, Kinghelm maintains integrated capabilities covering product design, tooling development, performance testing, and volume manufacturing. This structured production process supports consistency and stable delivery for connector products across different application requirements.
