Molex PCB Header, Straight, 20 Way - Micro-Fit 3.0 Series - 43045-2012

For the stable attachment of conductors to your PCB, choose this straight header from Molex. It features 20 contacts arranged in 2 rows to accommodate and organise multiple conductors. To ensure a secure connection, you can solder this header to your board. Its thermoplastic body is resistant to impact and heat for use in harsh industrial environments. Thanks to a voltage rating of 600V, it's suitable for use in high-powered applications.

• Tin-plated brass contacts are highly conductive and corrosion-resistant for stable transmissions

• Polarised to prevent incorrect mating

• Wide operating temperature range between -40°C and +105°C for use in challenging settings

Applications

• Robotics systems

• Telecommunications

• Manufacturing

• Automotive engineering

• Household appliances

How long will this PCB header last?

This header has a maximum durability rating of 30 mating cycles, so you can rely on it for long-term performance.

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
