The DC Jack 5.5x2.1mm PCB Mount is a standard barrel-type power connector engineered for reliable DC power input on printed circuit boards (PCBs). Featuring a 5.5mm outer diameter and a 2.1mm center pin, this through-hole mount jack is compatible with common 5.5x2.1mm DC plugs found on wall adapters and power supplies. It supports a maximum current of 5A and a voltage rating of up to 24V, making it suitable for powering devices like routers, LED strips, and DIY electronics projects such as Arduino or Raspberry Pi builds. The jack typically includes three pins: one for positive (center pin), one for negative (sleeve), and an optional switched pin that disconnects internal power (e.g., a battery) when a plug is inserted. With a contact resistance of ≤30mΩ and insulation resistance of ≥100MΩ at 500VDC, it ensures stable and efficient power delivery. Ideal for hobbyists and professionals, this RoHS-compliant component is easy to solder onto PCBs and operates within a temperature range of -30°C to 70°C.
