SMD Power Jack Socket Connector

A SMD Power Jack Socket Connector is commonly referred to as a DC power jack and has a center conductor with a hole in it to accept the male pin. The size of the DC jack is 3.5mm. These connectors are highly insulated. These types of dc power supply connectors are commonly used in mobile chargers, battery chargers, etc. The mating or contacting parts are made from high-quality copper material which protects data or electricity fluctuation for better performance. These connectors have a PCB mount design for easy installation.

The SMD power jack socket connector is a surface-mount component designed to provide reliable DC power input for compact electronic devices. Built for automated PCB assembly and optimized for space-saving designs, this connector type is becoming increasingly popular in consumer electronics, IoT devices, and portable systems where efficiency, durability, and low-profile integration are essential.

An SMD (Surface-Mount Device) power jack is a DC socket that mounts directly onto the surface of a printed circuit board (PCB) rather than using traditional through-hole pins. It accepts a standard barrel-style DC plug—typically 5.5mm (outer diameter) × 2.1mm or 2.5mm (inner diameter)—and connects it to the internal power circuitry of the device.

Unlike through-hole jacks, which require drilled holes and manual soldering, SMD jacks are ideal for automated pick-and-place assembly, helping reduce production time and cost.

Key Features

• Surface Mount Technology (SMT)
  Supports high-speed, automated assembly processes with better layout flexibility. Perfect for compact and high-density PCB designs.

• Low Profile and Compact Size
  Takes up minimal board space and vertical height—ideal for slim devices like tablets, wearables, and portable test gear.

• Reliable DC Power Input
  Compatible with industry-standard barrel plugs, providing steady, low-voltage DC power for embedded and consumer electronics.

• Durable and Long-Lasting
  Often constructed with nickel-plated contacts and heat-resistant plastic housing for excellent mechanical and electrical performance.

• Optional Shielding
  Some SMD power jacks include metal shields for enhanced EMI protection and grounding—important in noise-sensitive designs.
