[Product Overview] DC-033 3.9mm Outer Diameter (Pin Core 1.0mm / 1.3mm Optional) Horizontal SMD SMT Fully Encapsulated DC Power Jack

DC-033 is a high-reliability horizontal SMD SMT micro DC power jack (female connector)designed for high-density portable devices. This product features an outer diameter of 3.9mmand, depending on the adapter requirements of different terminal devices, offers 1.0mm pin core and 1.3mm pin core Two standardized specification options for precise matching of various miniature power connectors.

The DC-033 features a fully encapsulated square housing structure with a neat and compact profile. It provides reliable dustproof and insulating protection, while its flat top surface is highly conducive to precise vacuum nozzle pick-up by SMT placement machines. Addressing the common issue of miniature sockets loosening under frequent insertion and withdrawal stress, the sides are equipped with bent metal reinforcement solder tabs, complemented by dual positioning posts at the base. After reflow soldering, these deliver exceptional resistance to lateral shear forces, effectively ensuring the stability and durability of the entire connector interface.

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

1. Pin core 1.0mm / 1.3mm dual specifications available for greater flexibility

Offered in 3.9×1.0mm and 3.9×1.3mm center pin specifications, allowing R&D engineers to flexibly select the appropriate option based on the power adapter male connector, without the need to modify the PCB footprint.

2. Compact structure design, maximizing PCB space savings

Featuring a small board footprint and low profile, it is specifically designed for miniature digital devices, portable medical equipment, and wearable/smart hardware with stringent space requirements, enabling PCB layout engineers to achieve higher-density component placement.

3. Tape & Reel packaging, fully supporting high-speed SMT assembly

Strictly packaged on industrial-grade carrier tape with coplanarity controlled to ≤0.10mm, combined with a flat pick-up surface, significantly enhancing automated assembly line placement efficiency and first-pass yield.

4. Side reinforcement solder tabs + dual bottom positioning posts, dual fatigue resistance protection

The high-strength metal reinforcement tabs on both sides distribute insertion and withdrawal stress across the PCB copper foil, while the dual bottom positioning posts prevent misalignment, effectively preventing pad peeling or cold solder joints caused by frequent plugging and unplugging.
