【Product Overview】DC-039A 5.1×1.65mm Through-Hole DIP Fully Encapsulated DC Power Jack
DC-039A (5.1×1.65mm) is designed to meet the demands of high stability and compact assembly, DIP through-hole DC power jack (female connector). This product precisely fits power adapter male plugs with an outer diameter of 5.1mmand a center pin diameter of 1.65mm power adapter male plug, fully satisfying the interface requirements of consumer electronics and small industrial equipment.
DC-039A adopts a fully encapsulated housing structure made of high-strength engineering plastic, with regular external dimensions (body width 9.0mm × length 13.0mm × height 11.0mm). The front of the jack features a 3.5mm wide panel positioning slot for precise alignment with the device enclosure panel. The bottom is equipped with a φ1.8mm PCB positioning post and bent support pins on both sides (2-2.0×0.8mm and 2.5×1.2mm), which evenly distribute insertion and extraction stress across the PCB after wave or hand soldering, delivering excellent mechanical strength.
---[Expert-Level B-Side Selling Points and B2B Procurement Decision Factors]
1. Precise miniature specification of 5.1×1.65mm
The center pin diameter is a standard 1.65mm, and the internal contact spring maintains lasting elasticity, ensuring tight insertion and extraction engagement, effectively preventing power loss caused by poor contact or vibration.
2. PCB positioning posts + double-side bent leg support, resistant to mechanical pull-out
The bottom is equipped with dedicated positioning posts and bent-shaped fixed solder legs, forming a triangular stable support on the PCB, significantly enhancing the solder joint's resistance to shear stress and plug-unplug fatigue.
3. Front panel slot design, easy for overall device structural assembly
The housing side features a front positioning slot (width 3.5mm), which can tightly engage with the panel slots of portable devices or instrument housings, achieving a neat and flat overall device appearance.
4. Compatible with wave soldering and manual soldering processes
The pins use high-quality easy-to-solder copper alloy with tin-plated surface treatment, offering good temperature resistance, suitable for both automated wave soldering production lines for mass manufacturing and convenient manual soldering for repairs.
