Molex PCB Header, 5A Current Rating, 250V Voltage Rating - Micro-Fit 3.0 Series - 43045-0800

Make wiring to a circuit board a walk in the park with this PCB header from Molex. It acts as a transmission link between your circuit and connected cables, keeping live parts under cover to boost user safety. Versatility and space efficiency are covered by its two-row, eight-contact design, which gives you multi-circuit control. Thanks to through-hole mounting, this unit latches firmly onto your board, making it the right choice for vibrating systems.

Features & Benefits

• Current rating of 5A makes it suitable for use in light-duty applications

• High-temperature thermoplastic housing withstands the heat and impact that come with harsh industrial settings

• Right-angle orientation for easy connection in tight setups

Applications

• Process and packaging equipment

• HVAC systems

• Industrial lighting

Is this header shrouded?

Yes. This unit is fully shrouded to keep EMI at bay and ensure you get the best signal quality.

Molex Micro-Fit 3.0 3.0mm Dual Row PCB Headers with Snap in Plastic Peg PCB Lock, 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 secure these Micro-Fit 3.0 headers to the PCB board, snap-in plastic peg PCB locks are incorporated into the connector design. 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

• Plastic peg PCB locks for secure connection to PCB

• Glow Wire Compliant
