3.96mm Pitch Vertical Male Pin Header Connector for Industrial Switching Power Supplies ;Control Boards

This product is an integrated, high-capacity 3.96mm Pitch Single-Row Straight Male Pin Header Connector. As a singular, non-split component, it features high-conductivity square brass pins precision-molded into a heavy-duty, heat-resistant black thermoplastic carrier insulator. Designed for vertical through-hole technology (THT) wave soldering onto PCBs, it establishes a highly stable and unyielding male docking interface for power distribution and sub-board connection loops.

• This large-pitch pin header is ideal for Industrial Switching Power Supplies (SMPS), inverter modules, and LED driver boards requiring robust power distribution. It is also widely used in Commercial Kitchen Appliances and White Goods (such as washing machine and refrigerator primary control boards), industrial automation motor controllers, HVAC relays, and any heavy electrical control system where a dense 2.0mm/2.54mm pitch cannot handle the raw amperage requirements.

• Standard micro-pitch headers often suffer from electrical arcing and creepage breakdown when exposed to the high voltages and current surges typical of power supply units. The expanded 3.96mm physical gap between the pins provides a large safety creepage distance, preventing localized high-voltage jumping. In white goods and industrial settings, continuous mechanical vibrations from motors can lead to terminal fretting corrosion and high contact resistance, causing the system to overheat or fail. Our precision-engineered gold-plated brass pins ensure a gas-tight, highly conductive joint that resists environmental oxidation and maintains stable milliohm contact performance. Finally, its rigid, single-piece structural design eliminates pin shifting or bent terminals during automatic factory board insertion lines, drastically minimizing assembly-line reject rates.
