Frequently Asked Questions
Q: What size DC plug is compatible with the DC-036A female socket?
A: The DC-036A female socket is designed to accept a standard 5.5mm outer diameter / 2.1mm inner diameter (5.5×2.1mm) DC barrel plug — one of the most commonly used sizes in electronics, power adapters, and Arduino/Raspberry Pi projects. Always verify your plug dimensions before connecting.
Q: How is the DC-036A socket mounted to a circuit board?
A: The DC-036A uses SMD (Surface Mount Device) soldering for board mounting. It can be positioned on the surface of a PCB and soldered into place using standard SMD soldering techniques, making it suitable for compact and professional circuit board layouts.
Q: What are the rated voltage and current limits for this socket?
A: This socket is rated for up to 30V DC at 0.5A. It is intended for low-current DC power connections in electronics, control systems, and similar applications. Do not exceed the rated specifications to ensure safe and reliable operation.
Q: Why does this socket have a metal cover instead of plastic?
A: The metal cover provides several advantages over standard plastic shells: improved electromagnetic shielding, greater mechanical durability, better heat dissipation, and a more secure fit — making it especially well-suited for industrial and professional electronics environments.
