[Product Overview] DC-103C Fully Gold-Plated "Front-SMD Rear-DIP" Mixed-Mount DC Power Socket with Positioning Post
DC-103C is a 90-degree DC power socket (female connector) designed for high-quality digital devices and smart hardware, featuring front-SMD rear-DIP (SMT + DIP hybrid mounting). This product ingeniously combines the positioning convenience of SMT surface mounting with the robust mechanical pull-out resistance of DIP through-hole soldering.
The DC-103C features gold-plated SMD reinforcement pads at the front and through-hole pins at the rear, complemented by precision anti-misalignment positioning posts on the bottom of the body, forming a "multi-point linked" physical support on the PCB. The fully gold-plated terminals and external reinforced clamp not only provide a premium appearance but also ensure ultra-low contact resistance and long-term oxidation resistance, effectively preventing pad peeling and tearing during repeated plugging and unplugging.

1. "Front-SMD Rear-DIP" hybrid structure enhances pull-out and tear resistance
By combining front-end SMT pads with rear-end DIP through-hole pins, this fixing method retains the flat alignment of SMD while significantly enhancing both vertical and horizontal resistance to plugging stress on the PCB through the through-hole pins.
2. Fully gold-plated terminals and reinforced locking clips for excellent conductivity and oxidation resistance
Both the conductive terminals and the external reinforced metal clips feature a thick gold-plated surface treatment, significantly reducing contact resistance and temperature rise, preventing oxidation during long-term use, and ensuring efficient signal and current transmission.
3. Precision positioning posts at the bottom for error-proof and misalignment-free mounting
The body features dual positioning posts at the bottom, enabling fast and precise alignment during PCB assembly, preventing misalignment during the soldering process, and ensuring the accuracy of through-holes and housing gaps in the final product.
