Rated at 250 V and 3 A, this component meets most low-to-medium-power power supply loops and ordinary signal transmission loops inside equipment. Tin-plated brass terminals reduce contact resistance to ensure stable current and signal transmission. The PA66 housing with UL94V-0 flame-retardant rating improves the fire-safety margin of end-products. Its wide operating temperature range from -25 ℃ to +85 ℃ guarantees stable wire-to-board connection under high- and low-temperature working conditions. Featuring a single-row straight-mount structure compatible with matching XH-series wires, it supports both wave soldering and manual soldering. Built-in anti-misinsertion lugs effectively prevent reverse or incorrect insertion during assembly and lower production defect rates. As a widely-accepted industry standard 2.5 mm pitch, supporting materials are readily available. The PA66 housing resists aging and stress cracking to avoid brittleness and damage over long-term service. Supplied in bags and requiring storage at 10 ℃-30 ℃ with relative humidity ≤70% RH, the product supports flexible order quantities for both R&D sampling and mass production to deliver a highly-adaptable supply-chain solution. Its anti-reverse-insertion lugs eliminate assembly errors and reduce commissioning failures of finished devices. Tin-plated brass terminals offer excellent conductivity and oxidation resistance to mitigate poor contact and signal interruption risks. Soldered through PCB holes, the through-hole pins deliver superior vibration and pull-out resistance compared with SMT counterparts, making it suitable for internal wiring under vibration and pulling stress.

In terms of appearance and mechanical structure, KH-2501GW-12A-Z adopts a single-row straight-mount body with PA66 flame-retardant housing for a compact and practical construction. Physical anti-misinsertion features prevent assembly mistakes. Through-hole soldered pins achieve robust connections and avoid contact anomalies caused by wire pulling or equipment vibration.

As a high-quality wire-to-board header, KH-2501GW-12A-Z delivers reliable overall performance. Its stable electrical performance adapts to ordinary-signal and low-to-medium-power supply applications. It provides dependable interconnection for consumer electronics, smart-home hardware and small-scale industrial-control equipment, maintaining steady connection even under drastic temperature swings and vibrating environments.

KH-2501GW-12A-Z serves a broad range of applications. Within consumer electronics, it connects internal power harnesses for LED light modules, home-appliance main-control boards and audio devices. For smart-home systems, it is used for internal module wiring of smart control panels, thermostats and robot vacuum cleaners. It can also be deployed for signal and power loops in small industrial-control terminals, instruments and partial on-board auxiliary equipment.
