【Product Overview】DC-109 Fully Shielded SMT Surface-Mount DC Power Jack with Positioning Pegs
DC-109 It is specifically designed for high-quality digital devices and industrial-grade control terminals. Fully shielded SMT surface-mount 90-degree DC power jack (female)The product features a fully enclosed metal shielding shell structure, cleverly integrating high-reliability EMI anti-interference design with robust mechanical soldering fixation capability.
The metal shield encasing the DC-109 not only effectively suppresses electromagnetic interference (EMI), but its extended grounding and fixing solder tabs greatly enhance the socket's resistance to pull-out and tear on the PCB. The bottom of the body is equipped with dual positioning posts, enabling rapid and precise alignment during SMT placement, significantly improving automated production efficiency and soldering reliability.

1. Fully enclosed metal shielding cover, resistant to EMI interference and reinforced against tearing.
The all-metal shell design provides excellent electromagnetic shielding performance, ensuring the purity and stability of power transmission; at the same time, serving as a structural reinforcement, it effectively disperses the insertion and extraction mechanical force to the PCB board, preventing pad tearing.
2. Precision positioning posts on the bottom for high-accuracy automated SMT placement
The bottom features dual positioning posts (diameter 1.20mm, pitch 3.50mm), enabling precise alignment during SMT reflow soldering to prevent placement defects such as misalignment and tombstoning.
3. High-quality conductive terminals for low temperature rise and long service life
High-quality gold-plated/silver-plated conductive terminals are adopted, with contact resistance ≤ 0.03Ω and a rated load of 30V 3.0A, meeting the requirements of high-efficiency power transmission and long service life for high-quality electronic equipment.
