Winchester Micro-D Surface-Mount Connectors for High-Reliability Electronics

Winchester Micro-D surface-mount (SMT) connectors are utilized in electronic systems across the aerospace, defense, medical, and industrial sectors. These components provide a mechanical and electrical interface designed to maintain connectivity under conditions of high vibration, shock, and environmental stress. The integration of these connectors into high-reliability applications ensures consistent performance in systems where operational stability is critical.

Mechanical Design and Space Management
The connectors employ a compact rectangular form factor featuring multiple rows of precision-engineered pins or sockets. This low-profile geometry supports the requirements of space-constrained applications, allowing for higher component density on printed circuit boards (PCBs). By utilizing surface mount technology, the connectors are soldered directly onto PCB copper pads. This method enables efficient automated assembly and establishes a robust electrical connection suitable for long-term deployment.

Electrical Specifications and Performance Parameters
Technical performance is defined by low contact resistance, specified at a maximum of 8 milliohms at the interface. Minimizing resistance is essential for maintaining signal quality in sensitive instrumentation. The devices support a current rating of up to 3A and exhibit a dielectric withstanding voltage of 600 VAC at sea level. At an altitude of 70,000 feet, the connectors maintain a breakdown voltage of 150 VAC with leakage current limited to 1 mA. Additionally, an insulation resistance of 5000 megohms at 500 VDC prevents internal electrical leakage, ensuring functional stability in variable atmospheric conditions.
