In stock at Powell Electronics, the supplier of connectors and more for high-rel applications including defence, aerospace and industrial, are the rugged Micro-D surface-mount connectors from Winchester. The devices provide a secure mechanical and electrical interface capable of withstanding high vibration, shock and other environmental stresses, making them ideal for the stringent demands of high-reliability electronic applications across aerospace, defense, medical and industrial sectors.
The connectors feature a compact rectangular form factor with multiple rows of precision-engineered pins or sockets, available in a wide variety of pin counts and configurations. The low-profile design supports space-constrained applications while maintaining signal integrity and long-term reliability. Designed for surface mount technology (SMT), the Micro-D connectors are soldered directly onto printed circuit board (PCB) copper pads, enabling efficient assembly and robust electrical performance.
Further technical details include a strong electrical performance, with contact resistance specified at 8 milliohms maximum for the contact interface, plus any additional resistance from solid leads depending on wire gauge, measured at 2.5A. The devices support a current rating of up to 3A and provide dielectric withstanding voltage of 600 VAC at sea level and 150 VAC at 70,000 feet, with leakage current limited to 1 mA. Insulation resistance is rated at a minimum of 5000 megohms at 500 VDC, ensuring reliable operation in demanding environments.
