Micro coaxial connectors

Micro coaxial connectors that meet the frequency requirements of a wide variety of miniature devices. The high frequency performance ranges from DC to 12GHz dependent on the series. The footprints are compact and the mated height profiles are as low as 0.95mm up to 3mm to save space on the board. Some connector series feature the same PCB layout to allow flexible design options. Halogen-free options are available.
