Molex 43045-1400 Micro-Fit 3.0 right-angle PCB header for compact wire-to-board power or signal connections in 3D-printer electronics, toolhead boards, and harness builds.
Why use this connector
- Micro-Fit 3.0 system: 3.00 mm pitch connector family for higher-density wiring than larger power connector formats.
- 14 circuits in a dual-row layout: useful where a board needs multiple toolhead, fan, heater, sensor, or accessory conductors through one keyed connector.
- Right-angle through-hole header: routes the harness parallel to the PCB instead of straight up from the board.
- Molex part 43045-1400: snap-in plastic peg PCB lock, matte tin plated contacts, black housing, glow-wire capable per Molex product data.

Gotchas

- It is a right-angle board connector, not a vertical header.
- Confirm PCB footprint, keying, and mating housing before ordering for an existing board revision.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
