Molex Micro-Fit 3.0 Series Right Angle Through Hole PCB Header, 20 Contacts, 3 mm Pitch, 2 Row, Shrouded 43045-2000

Molex 43045-2000 Micro-Fit 3.0 Series Right Angle Through Hole PCB Header is a compact, high-performance wire-to-board connector designed for reliable electrical connections in industrial, electronic, and power distribution applications. Featuring a 3 mm pitch with 20 male contacts arranged in two rows, this connector supports a current rating of 5A and a voltage rating of 250V, making it suitable for low to mid-range power systems.

The connector incorporates a shrouded design with positive latching provided by a locking ramp on the housing, preventing accidental disconnection. The housing is manufactured from high temperature UL 94V-0 Liquid Crystal Polymer thermoplastic, capable of withstanding soldering temperatures up to 265°C during IR reflow processing.

With through hole mounting and plastic peg PCB locks, the PCB header ensures secure mechanical and electrical connection to the board. The contact material is brass with tin plating, balancing cost and performance while offering corrosion resistance and reliable conductivity. The connector's right angle orientation and 3 mm mating pin length facilitate ease of assembly and integration on PCB layouts.

Operating effectively across a temperature range from -40°C to 105°C, this connector suits use cases in military COTS equipment, solar power systems, consumer appliances such as dryers and refrigerators, telecommunications, medical devices, and gaming terminals. The fully isolated dual beam terminals reduce electrical arcing, enhancing long-term operational reliability.

Dual row shrouded connector for secure mating and electrical reliability. High-temperature thermoplastic housing supports IR reflow soldering. Rated for 5A current and 250V voltage in compact footprint. Through hole mounting with plastic peg locks for secure PCB attachment.

Brass contacts with tin plating provide reliable conductivity and corrosion resistance. Right angle connector orientation with 3 mm pin length facilitates PCB integration. Wide operating temperature range from -40°C to 105°C.

Fully isolated dual beam contact terminals minimize arcing and improve electrical performance.
