【Product Overview】DC-057 All-Metal Reinforced SMT Sinking DC Power Jack
DC-057 is specifically designed for ultra-thin electronic products and high-density PCBs. SMT SMD 90-degree DC power jack (female)The product is wrapped on the outside of the plastic body. High-strength all-metal shielded ruggedized enclosure, and is equipped with large-area reinforced solder joints on the sides and tail, solving the problem of the interface in ultra-thin devices being prone to falling off or tearing the solder pads during frequent plugging and unplugging.
DC-057 base is equipped with Central PCB mechanical positioning postDuring the SMT automatic placement process, it can precisely lock into position to prevent skewing, while the front opening structure offers good compatibility for panel and housing assembly, fully meeting lead-free reflow soldering process requirements.

1. Full metal-clad housing, resistant to EMI/ESD electrostatic interference
The entire housing is covered with highly conductive metal, providing excellent electromagnetic shielding performance and electrostatic discharge capability, effectively protecting against instantaneous electrostatic breakdown (ESD) and reducing high-frequency electromagnetic interference.
2. Multi-point reinforced mounting pads, improving lateral pull resistance by 180%
Dedicated reinforced soldering pads extend from the sides of the metal housing, forming solid solder joints with the PCB copper foil after reflow, evenly distributing mechanical stress from plugging/unplugging and external pulling forces to prevent pad peeling or cracking.
3. Ultra-thin recessed mounting compatibility and precise PCB positioning
The compact low-profile design, combined with dedicated positioning posts at the bottom, not only assists PCB layout engineers in saving vertical space on the board but also ensures high yield rates in automated SMT placement.
