Molex Micro-Fit 3.0 Series Right Angle Through Hole PCB Header 18 Contacts 3 mm Pitch 2 Row Shrouded 43045-1800

Molex 43045-1800 Micro-Fit 3.0 Series Right Angle Through Hole PCB Header is a dual-row, 18-contact wire-to-board connector with a 3 mm pitch, designed for compact power and signal connections on printed circuit boards. It supports currents up to 5A and operates at voltages up to 250V, providing a reliable connection in a small footprint.

The shrouded housing features positive latching with a locking ramp on the housing to secure the mating connection and prevent accidental disconnection. Contacts are manufactured from brass with tin plating to ensure corrosion resistance and durability under various operating conditions.

The connector is compatible with through hole mounting and is SMT compatible, helping to reduce manufacturing complexity and cost. The housing material is high-temperature UL 94V-0 Liquid Crystal Polymer, resistant up to 265°C, enabling it to withstand the IR reflow soldering process without damage.

Snap-in plastic peg PCB locks provide firm and secure attachment to the PCB board, preventing movement during assembly or operation. The contacts are fully isolated within the housing to reduce electrical arcing and ensure consistent contact performance.

Operating temperature ranges from -40°C up to 105°C, making this connector suitable for a wide range of industrial, military, and commercial applications, including solar power systems, consumer products such as dryers and washing machines, data communication equipment like routers and servers, medical devices, telecommunications gear, and gaming terminals.

Features include high current capacity, high temperature housing, positive latching, SMT compatibility, and secure PCB mounting. The connector is Glow Wire compliant and designed for efficiency and reliability in low to medium power circuits.

High current carrying capacity of up to 5A in a compact footprint. Shrouded housing with positive latching prevents accidental disconnection. Brass contacts with tin plating for corrosion resistance. Through hole mounting with SMT compatibility for reduced costs.

High-temperature UL 94V-0 housing withstands IR reflow soldering up to 265°C. Snap-in plastic peg locks secure the connector to the PCB. Operating temperature from -40°C to 105°C for demanding environments. Fully isolated contacts reduce electrical arcing and improve reliability.
