February 13, 2014 – Molex releases Mega-Fit power connector that provides 23.0A in a small 5.70mm footprint, making them suitable for applications requiring power from 14.0 to 23.0A per terminal.
The split-box terminal design staggers six contact points, each of which moves independently on a separate flexible beam in order to deliver a redundant, secondary current path for long-term reliability. The staggered contacts allow the front four “sacrificial” contacts to protect the two rear points of contact when un-mating, allowing the system to be "hot plugged" at 48V/23.0A and up to 30 cycles. The terminals also feature an extended barrel conductor crimp providing an extremely strong terminal-to-wire retention, which provides long-term durability and reliability.
The Mega-Fit 5.70mm pitch connectors have isolated terminals, positive housing locks and polarized housings. Numerous applications would benefit from the Mega-Fit 5.70mm pitch connectors, including;
- Power delivery requirements between 14.0 and 23.0A: Many general market mid-range power connectors are rated below 14.0A.
- When low power applications benefit from “power headroom”: Mega-Fit power connectors can also be used when additional current carrying capacity is preferred rather than using the maximum power on a smaller connector.
- To replace lower power connectors being used for current sharing: In some applications, design engineers may introduce current sharing, or splitting power between contacts with lower power connectors in order to achieve up to 23.0A.
The Mega-Fit system not only provides power delivery in the higher range, but it does so in a compact size, allowing more power without sacrificing PCB space.
However, it is not only safer to use one current path with the Mega-Fit power connector, but it also reduces the PCB footprint.
