Molex Micro-Fit 3.0 Series Straight Through Hole PCB Header 3 Contacts 3 mm Pitch 1 Row Shrouded 43650-0327

Molex 43650-0327 Micro-Fit 3.0 Series Straight Through Hole PCB Header is a high-performance connector designed for wire-to-board applications requiring reliable power distribution. Featuring a 3.0 mm pitch and 3 male contacts arranged in a single row, this PCB header integrates a shrouded housing made from heat-resistant liquid crystal polymer material. The housing material withstands up to 265°C during infrared reflow soldering, enabling robust manufacturing processes.

The Micro-Fit 3.0 connectors support currents up to 5 amperes within a compact footprint, making them ideal for low to mid power electronic devices. The connector assembly includes positive latching via a locking ramp on the housing, which secures mating parts and prevents unintentional disconnection in demanding industrial or consumer environments.

Designed for through-hole mounting, this PCB header is compatible with surface-mount technology (SMT) processes, providing flexibility and cost efficiency during PCB assembly. Integrated PCB polarizing pegs aid precise positioning and alignment of the connector on the circuit board, while kinked solder legs (available on certain part variations) enhance mechanical retention.

The contacts are brass with tin plating, fully isolated within the housing, reducing the risk of electrical arcing and ensuring consistent signal integrity. Operating temperature ranges from -40°C to +105°C enable application across diverse environmental conditions. The connector operates at voltages up to 250V, suitable for commercial, medical, telecommunications, and consumer electronics sectors.

Applications include military commercial off-the-shelf (COTS) systems, solar power equipment, household appliances such as dryers and freezers, data communications hardware, medical devices, gaming terminals, and telecommunications infrastructure. Compliance with glow wire standards ensures safety and performance reliability in practical use cases.

Compact wire-to-board connector supporting 5A current capacity. High-temperature liquid crystal polymer housing rated for up to 265°C during IR reflow soldering. Positive latching feature ensures secure connection and prevents accidental disconnection.

Through hole mounting compatible with SMT process to reduce manufacturing costs. PCB polarizing pegs provide reliable positioning and alignment on the board. Contacts are made of brass with tin plating for effective electrical conductivity.
