Micro RF connector provides enhanced board design flexibility

Hirose has developed a micro RF connector with a low profile of only 1.2mm when mated. Offering design flexibility, the space-saving K.FL2 Series connector is obtainable in an RF cable mating type and an FPC-to-board mating type. Both versions support high-density mounting to save valuable PCB real estate further.

The micro RF connector produces excellent high-frequency performance and has a low VSWR of 1.3 Max: 0 to 3GHz; 1.5 Max: 3 to 6GHz; 1.6 Max: 6 to 8GHz. Compatible with pick-and-place mounting, the series connector is commonly used in consumer applications, including laptop computers, smartphones, tablets, VR/AR glasses, routers, and more.

The series uses a tapered design for easy mating with greatly decreased insertion force. A polarity key makes it easy to identify the mounting direction, and a clear tactile click confirms proper mating.

A robust, integrated plug design prevents plug deformation during un-mating while providing high retention force. Solder wicking and flux penetration is prevented via a nickel barrier at the shell and contact.

“Hirose continues our tradition of downsizing connector footprints while increasing performance and reliability to meet application specific demands,” said Pete Lais, assistant vice president of Product Management for Hirose Electric Americas. “The K.FL2 Series micro RF connector not only features a space-saving design and high-density mounting capability but also offers design flexibility to better support application requirements.”
