4 Pin SMT DC Power Jack for Right-Angle PCB Mounting

The DC-085 is a 4 pin SMT DC power jack — a right-angle surface-mount DC receptacle designed for compact PCB layouts where automated assembly and reliable power delivery are required. This 4 pin SMD DC power jack provides a secure interface for external DC power adapters, making it suitable for consumer electronics, industrial equipment, medical devices, and portable instruments.

This SMT DC power jack features four pins — two electrical contacts for power transmission and two mechanical anchor pins for enhanced PCB retention. The right-angle orientation positions the connector parallel to the PCB surface, enabling edge-mount installation that saves vertical space and simplifies enclosure design. The 4-pin configuration provides stable mechanical anchoring, reducing the risk of solder joint failure under repeated plug insertion and withdrawal.

Manufactured in an ISO 9001:2015 certified facility, this PCB mount DC power jack is fully compliant with RoHS 3 and REACH regulations. Available in tape-and-reel packaging for automated SMT assembly, with OEM customization options for volume orders.

Below are the complete specifications for the SMT DC power jack DC-085, covering electrical, mechanical, and environmental ratings.

Specifications should be verified against the latest product drawing and engineering documentation before production release. Electrical performance depends on the complete power delivery system, including the connector, PCB layout, power supply, and load requirements.

A 4 pin SMD DC power jack offers several advantages for PCB designers working on compact electronic devices. The four-pin configuration provides two electrical contacts for power transmission and two mechanical anchor pins for enhanced PCB retention. This design reduces the risk of solder joint failure under repeated plug insertion and withdrawal — a common failure mode in portable electronics and frequently connected devices.

When selecting a 4 pin SMD DC power jack for your design, consider the mechanical and electrical requirements of your application. The SMT termination supports automated reflow soldering, making it suitable for high-volume production. The right-angle orientation positions the connector parallel to the PCB surface, enabling edge-mount installation that saves vertical space and simplifies enclosure design.

For engineers designing portable devices, the 4-pin SMD DC power jack provides a reliable power interface that balances mechanical strength with manufacturing efficiency.

An SMT DC power jack is designed for surface-mount PCB assembly using automated reflow soldering processes. Compared with through-hole DIP versions, SMT DC power jacks offer several advantages for high-volume production. First, they eliminate the need for drilled through-holes, reducing PCB fabrication costs and increasing board density. Second, they support automated pick-and-place assembly, reducing labor costs and improving production consistency. Third, they are compatible with standard reflow soldering profiles, enabling efficient manufacturing workflows.

The SMT DC power jack is particularly well-suited for compact consumer electronics, portable devices, and applications where board space is at a premium. However, engineers should consider the mechanical requirements of their application — through-hole DIP versions may offer superior mechanical strength for applications subject to high cable pull forces or frequent plug insertion.

A PCB mount DC power jack should be selected according to both electrical and mechanical requirements. The connector needs to align accurately with the enclosure opening while maintaining enough clearance for the mating plug and cable. At the PCB level, the footprint must provide appropriate pads, mounting holes, grounding features, and routing space.

When designing the PCB footprint for this PCB mount DC power jack, engineers should consider the following:

• Pad size and shape: Follow the manufacturer’s recommended land pattern for optimal solder joint reliability.
• Anchor pin clearance: Ensure adequate clearance for the mechanical anchor pins to pass through the PCB.
• Component placement: Position the connector at the PCB edge with the port opening aligned to the enclosure cutout.
• Trace routing: Route power traces with adequate width for the rated current (0.5A).

The connector itself is only one element in the complete power delivery system. PCB trace geometry, component placement, and thermal management can all affect overall system performance.

A right angle DC power jack positions the connector parallel to the PCB surface, enabling edge-mount installation that saves vertical space and simplifies enclosure design. This orientation is particularly useful in slim devices where vertical clearance is limited — such as portable electronics, set-top boxes, and compact industrial equipment.

The right-angle orientation offers several advantages over vertical mounting. First, it allows the connector to be placed at the PCB edge, with the port opening aligned to the enclosure side panel. Second, it reduces the connector’s height above the PCB, enabling thinner product designs. Third, it simplifies cable routing by allowing the power cable to enter from the side rather than the top of the device.

When designing with a right angle DC power jack, engineers should consider the mechanical clearance required for cable insertion and bending. Allow adequate space beyond the board edge for the connector body, cable plug, and cable strain relief.

When selecting a DC power jack for your PCB, understanding the differences between SMT and DIP mounting is essential. The table below compares the key characteristics.

What Is a 4 Pin SMT DC Power Jack?

A 4 pin SMT DC power jack is a surface-mount DC receptacle designed for PCB integration in compact electronic devices. The DC-085 features a right-angle orientation and four pins — two electrical contacts for power transmission and two mechanical anchor pins for enhanced PCB retention. This configuration provides reliable power delivery while maintaining mechanical stability under repeated plug insertion and withdrawal.

The 4-pin SMT DC power jack is commonly used in consumer electronics, industrial equipment, medical devices, and portable instruments where space is limited and automated assembly is required. The SMT termination supports reflow soldering, making it compatible with high-volume PCB assembly lines.

SMT vs DIP DC Power Jacks — Making the Right Choice

When selecting a DC power jack for your PCB, the choice between SMT and DIP mounting depends on your mechanical requirements and production volume. SMT DC power jacks are designed for automated reflow soldering processes. They are smaller, allow for higher-density PCB layouts, and significantly reduce assembly costs in high-volume production. However, they offer slightly lower mechanical pull-strength compared to through-hole versions.

DIP (through-hole) DC power jacks have pins that pass through the PCB and are soldered on the opposite side. They provide superior mechanical anchoring, making them ideal for products that experience frequent plugging/unplugging, heavy cables, or vibration. They are also easier to hand-solder for prototyping and low-volume production.

The DC-085 is an SMT connector. Choose this for compact PCB designs and automated assembly. For applications requiring maximum mechanical strength, consider through-hole DC power jack options.

Right-Angle DC Power Jack — When to Use It

A right angle DC power jack positions the connector parallel to the PCB surface, enabling edge-mount installation that saves vertical space and simplifies enclosure design. This orientation is particularly useful in slim devices where vertical clearance is limited — such as portable electronics, set-top boxes, and compact industrial equipment.

The right-angle orientation offers several advantages: it allows the connector to be placed at the PCB edge with the port opening aligned to the enclosure side panel; it reduces the connector’s height above the PCB, enabling thinner product designs; and it simplifies cable routing by allowing the power cable to enter from the side rather than the top of the device.

Battery-powered devices, communication equipment, and lighting controls all benefit from the DC-085’s reliable right-angle SMT design.

PCB Layout Considerations

When designing with this PCB mount DC power jack, engineers should follow the manufacturer’s recommended land pattern for optimal solder joint reliability. The connector should be placed at the PCB edge with the port opening aligned to the enclosure cutout. Power traces should be routed with adequate width for the rated current (0.5A). The mechanical anchor pins require appropriate clearance on the PCB.
