DC power jack – stable & reliable power connector
A DC power jack is a common connector for receiving direct current (DC) power, typically mounted on a PCB or device chassis. It is widely used in laptops, desktop computers, cameras, routers, headphones, audio equipment, and other electronics requiring stable power.
Available in various center pin diameters, the most common are 2.1 mm and 2.5 mm, matching the inner sleeve of DC power plugs. High-current models can handle up to 8 A, making them suitable for demanding applications.
