【Product Overview】DC-043 4.5×1.65mm Horizontal DIP Ultra-Compact DC Power Jack

DC-043 (4.5×1.65mm) is designed for space-constrained, high-density circuit designs horizontal 90-degree DIP through-hole design. This product precisely fits power adapter male plugs with an outer diameter of 4.5mmand a center pin diameter of 1.65mm , widely used in portable digital devices and small smart devices.

DC-043 adopts a high-strength engineering plastic head structure, with an extremely compact profile (body width 8.0mm × length 10.0mm × height 6.0mm). The base is equipped with dual PCB positioning posts (2-Φ2.0mm, pitch 4.0mm), which, combined with the 3-terminal solder lug design, not only ensures precise alignment during mounting but also significantly enhances the socket's resistance to shear stress from lateral insertion and withdrawal forces.

[Expert-Level B-Side Selling Points and B2B Procurement Decision Factors]

1. Precision miniature specification of 4.5×1.65mm

The center pin diameter is a standard 1.65mm, with internal high-elasticity, tough copper alloy contact springs, ensuring tight engagement during insertion and withdrawal, excellent electrical conductivity, and long-term protection against arcing and poor contact.

2. Dual PCB positioning post design, improving shear and pull-out resistance by 50%

Two Φ2.0mm mechanical positioning posts are provided at the bottom, effectively absorbing lateral torque and mechanical stress during insertion and withdrawal, protecting solder pads from detachment or cracking.

3. Ultra-compact PCB footprint, maximizing space savings

The body projection area is only 8.0mm × 10.0mm, with a height of just 6.0mm, greatly reducing on-board space occupation, making it ideal for ultra-thin portable products with stringent thickness and area requirements.

4. Easy solderability and high reliability

The pin surface adopts a high-quality easy-soldering tin plating process, and the high-temperature-resistant plastic body can withstand the wave soldering process, ensuring a high yield rate during mass production.
