Molex Straight PCB Header, 6 Way, 2 Rows - Micro-Fit 3.0 Series - 43045-0612


Use this straight PCB header from Molex to join six wires to a PCB. It's part of the Mini-Fit 3.0 series so offers easy compatibility across the range. Each contact has a 3mm pitch and the unit handles up to 5A (amperes) currents, making it a practical solution for low-range power transfers. The six terminals are positioned in two rows to create a thick block connection that receives both data and power transfers. Each wire is fully isolated in the housing to prevent electrical interference between contacts.

• Raised ramp design on the top of the header secures with the Micro-Fit receptacle latch

• Housing clicks when successfully locked in place to provide clear connection confirmation

• Shrouded terminal shields contacts from corner pressure mishandling to prevent damage

• Polarised pegs ensure wires are mated correctly for optimal performance

Applications


• Consumer white goods

• Office equipment

• Industrial automation equipment

• Rack-mount servers

• Routers and switches

What's this PCB header made from?


This PCB header is made from a high-temperature thermoplastic resin holding brass contacts. The contacts are coated in tin to prevent corrosion wear.

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
