【Product Overview】DC-031A Horizontal SMD SMT DC Power Jack with Reinforced Shield Cover

DC-031A is a connector specifically engineered for automated placement processes, . This product perfectly fits the internationally standard5.5×2.1mm and and 5.5×2.5mm fully aligned with the SMT Mount industrial-grade connector design standards for standard adapter power plugs.

DC-031A has been structurally redesigned based on the classic SMD jack: the periphery is enhanced witha high-strength all-metal reinforced shield shell, and the bottom features precise PCB positioning posts. During the SMT reflow soldering process, the side feet of the metal shield can be soldered over a large area onto the PCB pads, greatly absorbing the axial and lateral stress caused by frequent plug insertion and removal, effectively preventing PCB copper foil tearing or cold solder joint failures due to forceful plugging.

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

1. Tape & Reel packaging, perfectly compatible with SMT automated placement

Strictly packaged according to industrial-grade SMT carrier tape standards, with coplanarity controlled within ≤0.10mm, perfectly compatible with vacuum nozzles of high-speed pick-and-place machines, significantly improving customer assembly line SMT production efficiency and first-pass yield.

2. Metal shielding cover with reinforced solder feet, significantly enhanced pull-out resistance

The externally wrapped metal reinforced housing not only provides excellent electromagnetic interference (EMI) shielding capability, but its widened side solder feet form sturdy soldering support points, increasing insertion and withdrawal pull force by over 50%, extending the overall equipment service life.

3. Bottom positioning post design to prevent placement misalignment

The plastic base comes with precision locating pegs, ensuring accurate positioning during SMT placement and reflow soldering, preventing the connector from twisting or shifting, and ensuring perfect alignment between the port and the chassis opening.

4. High-temperature-resistant PA9T / LCP engineering plastic base

Made of high-temperature-resistant engineering materials compliant with UL94V-0 flame retardant rating, capable of withstanding peak reflow soldering temperatures (260°C) for over 10 seconds, with no deformation, blistering, or compromised insulation performance after reflow.
