【Product Overview】DC-002F Horizontal PCB Mount Small Aperture DC Power Jack

DC-002F is a high-quality PCB board-mounted miniature DC power jack (female connector)specifically designed for miniaturized, lightweight electronic devices. This product adopts a classic right-angle horizontal board-mount structure with a standard 3-pin solder terminal design, primarily matching 3.5×1.1mm and 3.5×1.35mm two types of small-specification DC power adapter male plugs.

Compared to traditional jacks, DC-002F features optimizations in its external structure and internal contact spring blades, offering a more compact size and more stable insertion/withdrawal clamping force. It is widely used in power input interfaces across various portable digital products, small appliances, medical testing instruments, and smart hardware terminals.

【Key B2B Selling Points and Process Advantages】

1. Compact miniature structure, greatly saving PCB space

DC-002F is specifically designed for compact circuit boards. Its ultra-small footprint effectively reduces the thickness and volume of end products, making it an ideal power interface solution for handheld devices and slim electronic products.

2. High-quality copper alloy contacts, low impedance and durable for repeated plugging

The internal conductive contacts are made of high-precision copper alloy, with a finely nickel-plated/silver-plated anti-oxidation surface treatment. The internal structure provides moderate clamping force, ensuring smooth insertion and extraction without loosening. After over 5,000 rigorous mechanical plugging life tests, it maintains excellent electrical conductivity.

3. Standard 3-pin configuration, easy to solder and compatible with wave soldering

It adopts a standard 3-pin solder terminal structure (including power positive, negative, and an auto-switching normally closed contact). The pins tin smoothly and resist soldering heat, perfectly compatible with automated wave soldering and manual soldering processes on factory assembly lines, effectively reducing cold solder joints and defect rates.

4. High-temperature-resistant flame-retardant housing, ensuring electrical safety

The socket's main housing is made of high-insulation, high-temperature-resistant engineering plastic (such as PBT/PA66), offering excellent heat resistance and impact strength. It resists deformation during reflow soldering or under high-load heat generation, ensuring the safety and stability of the device's power input.
