Molex Micro-Fit 3.0 Series Right Angle Surface PCB Header 4 Contacts 3 mm Pitch 2 Row Shrouded 43045-0406

Molex 43045-0406 Micro-Fit 3.0 Series Right Angle Surface PCB Header features a dual row, 4-contact, 3 mm pitch design engineered for reliable wire-to-board power connections. The connector's shrouded housing utilizes high-temperature UL 94V-0 liquid crystal polymer thermoplastic material designed to withstand reflow soldering temperatures up to 265°C. The contacts are male brass with tin plating, ensuring stable electrical performance with a current capacity of 5 amperes and voltage rating of 250 volts. This header includes positive latching to prevent accidental disconnection and metal press-fit retention clips that secure the connector firmly to the PCB board.

With an operating temperature range from -40°C to 105°C, this connector supports a wide variety of industrial and commercial applications including military commercial off-the-shelf (COTS) units, solar power systems, consumer appliances such as dryers and fridges, data communications equipment like routers and servers, medical devices, telecommunications hardware, and gaming terminals. The 3 mm pitch and dual-row configuration make it highly suitable for compact power distribution solutions where space is limited and reliability is paramount.

These Micro-Fit 3.0 headers are SMT compatible due to their through-hole mounting design, reducing assembly complexity and cost. Their fully isolated dual beam terminals ensure excellent electrical contact quality and minimize arcing, contributing to safer and more durable connections. The header's glow wire compliance adds an extra level of fire safety assurance, important in demanding environments.
