Molex Micro-Fit 3.0 Series Straight Through Hole PCB Header, 10 Contacts, 3 mm Pitch, 2 Row, Shrouded 43045-1013

The Molex 43045-1013 Micro-Fit 3.0 Series Straight Through Hole PCB Header is a high-quality wire-to-board connector designed for reliable power distribution in electronic components and assemblies. This connector features 10 gold-plated brass contacts arranged in 2 rows with a 3 mm pitch, providing compact yet robust electrical connections suitable for a wide array of low to mid power applications.

Manufactured with a housing of high temperature thermoplastic material certified for UL 94V-0, it endures IR reflow soldering temperatures up to 265°C, ensuring durability and reliability in assembly processes. The shrouded design includes positive latching with a locking ramp mechanism to secure mating and prevent accidental disconnection during operation or handling.

PCB polarising pegs integrated into the housing assist precise alignment and positioning on printed circuit boards, while kinked solder legs enhance mechanical retention on the PCB, contributing to the connector’s stability under vibration and mechanical stresses. The contacts are fully isolated within the housing to reduce arcing and improve safety.

Designed for through hole mounting with SMT compatibility, this PCB header simplifies manufacturing processes and reduces costs while maintaining strong mechanical attachment. Its male contact gender and 3 mm mating pin length ensure secure and reliable mating with corresponding connectors.

This series supports high current capacity up to 5A, with voltage rating up to 250V, making it suitable for various industrial and commercial applications including military COTS products, solar power systems, consumer electronics such as dryers and refrigerators, data communication equipment like servers and routers, medical devices, telecommunications, and gaming terminals.

Compact power connector system with high current carrying capability in a small footprint. High temperature housing supporting IR reflow soldering processes. Positive latching for secure and reliable mating connections. PCB polarising pegs for accurate positioning and kinked solder legs for additional retention.

Gold-plated brass contacts for excellent conductivity and corrosion resistance. Compatible with through hole mounting and SMT processes, reducing assembly complexity and cost. Designed for use in diverse applications including military, solar, consumer products, medical, and telecommunications.
