DC Power Jack PCB Mount 5.5×2.1mm — 2-Pack
A 5.5×2.1mm DC barrel jack PCB mount socket — pack of 2 — for adding a standard DC power input to custom PCBs. Through-hole mounting with three solder pins (positive center, negative sleeve, and mechanical anchor). Compatible with all standard 5.5×2.1mm DC barrel plugs used on Arduino power adapters, LED drivers, and most DC power supplies. The same connector used on Arduino Uno and Mega boards.
Key Specifications
- Connector: 5.5×2.1mm DC barrel jack (female, PCB mount)
- Mounting: Through-hole (3 pins)
- Current rating: 5A | Voltage rating: 30V DC
- Center pin: Positive (+) | Sleeve: Negative (−)
- Pack: 2 jacks
- Compliance: RoHS compliant
Why Choose This?
- ✅ Arduino-compatible — same 5.5×2.1mm connector as Arduino Uno and Mega
- ✅ Through-hole PCB mount — secure, solderable connection for custom PCBs
- ✅ 5A / 30V rated — suitable for Arduino, LED strips and most DC electronics
- ✅ Mechanical anchor pin — prevents connector from pulling out under cable stress
Typical Applications
- Custom Arduino-compatible PCB DC power input
- LED driver and controller PCB power jack
- Custom electronics PCB DC power connector
- Robotics controller PCB power input
