43045-0812, Molex Micro-Fit 3.0 Series Straight Through Hole PCB Header, 8 Contact(s), 3.0mm Pitch, 2 Row(s), Shrouded

Molex Micro-Fit 3.0 3.0mm Dual Row PCB Headers with PCB Polarizing Peg, 43045 Series

Micro-Fit 3.0 3mm pitch wire to board dual row PCB headers which form part of a compact power connector system providing a low to mid-range power distribution solution. With the ability to carry up to 5A of current, Micro-Fit 3.0 connectors have one of the highest current carrying abilities in the smallest footprints available. These Micro-Fit 3.0 PCB headers incorporate positive latching in the form of a locking ramp on the housing for secure mating and to prevent accidental disconnection. The housings are made of high-temperature UL 94V-0 Liquid Crystal Polymer that can withstand temperatures of up to 265°C during the IR reflow soldering process. The through hole mounting versions of these Micro-Fit 3.0 headers are also SMT compatible which means a reduction in process requirements and costs. To help position and align these Micro-Fit 3.0 headers to the PCB board, PCB polarising pegs are incorporated into the connector design. part numbers ending in xx12, xx13 and xx14 also feature kinked solder legs for additional PCB retention. The contacts of these Micro-Fit 3.0 headers are fully isolated within the housings to reduce arcing. Tin or a choice of two thicknesses of gold contact platings are available to keep down costs.

Features and Benefits

• High current carrying capacity in a small footprint
• High temperature housings for IR reflow soldering
• Through hole versions SMT compatible
• Positive latching for secure mating connection
• Fully isolated dual beam terminals for reliable electrical performance and contact
• PCB polarising pegs for alignment and positioning on PCB
• Kinked solder legs for additional PCB retention
• Glow Wire Compliant

Molex PCB Header, 5A Current Rating, 3mm Pitch - Micro-Fit 3.0 Series - 43045-0812

Deliver power to your board the easy way with this PCB header from Molex. It's compatible with simple through-hole mounting and gives you eight contacts across two rows, with each contact capable of carrying up to 5A of current. This means you get a lot of connectivity from one space-efficient unit. As the header has a 3mm pitch, it's ideal if you're looking for a compact yet versatile solution.

Features & Benefits

• Brass contacts with tin plating provide good conductivity and resist corrosion
• Voltage rating of 250V suits high-power applications
• Performs reliably in an operating temperature range between -40°C and +105°C
• Connectors are shrouded for protection and enhanced durability

Applications

• Telecommunications systems
• IT networking
• Consumer goods

Are the contacts on this PCB header isolated?

Yes. Each of the contacts is fully isolated inside the housing to prevent arcing and boost fire safety.
