Overview


The rising demand for smaller, ultracompact devices is driving industries’ needs for miniaturized, reliable and robust connectors with various design options. Many designs require a complex combination of high-current power and high-operating temperatures and electrical reliability and design flexibility. Molex SlimStack Microminiature Board-to-Board and Board-to-FPC Connectors provide a wide range of design options to ensure a reliable connection. These micro/fine-pitch plugs and receptacles feature voltage ratings of up to 125V, operating temperatures up to 125℃, current ratings up to 5.0A for signal connectors, and 15.0A for battery connectors. Additionally, SlimStack SSB and SSB RP Stacking Connector series provide various stack heights.

Customers need an easy mating option that prevents the housing from getting damaged during blind mating and high-power delivery. The nail structure offers wide alignment and robustness. The metal-power-armor nail provides housing protection of up to 3.0A power, electrical reliability and a clean contact point that supports nail structure requirements for various applications. The cover nail prevents housing from being damaged during blind mating up to 50N of force, 0.80mm displacement and 5.0A power. The short body and the nail structure of the stacking connectors prevent housing damage during mating while offering PWB design flexibility.

SlimStack 5G mmWave RF Flex-to-Board and Board-to-Board connectors offer reliable and stable performance with signal integrity (SI) for ultra-low profile and extreme RF applications. The multi-RF board-to-board connectors 5G15 (5 GHz) and 5G25 (25 GHz) feature various size options to provide additional design flexibility.
