IEE Aurora FFD12 Minitron Display  
Written by AnubisTTP on 2012-03-23  


The IEE Aurora handbook contains no mention of any filament displays with patterns other than a traditional seven segment, but the FFD12 is just such a device. The FFD12 contains only four filaments, arranged in the traditional 'plus one' configuration used to display polarity and overflow conditions. Though plus one displays are common amongst other display technologies for use in calculators and digital meters, minitrons with such a pattern are very rarely seen and this is one of the only examples of such a device that we know of. The FFD12 has a package height of 22mm, making it approximately 25% smaller than IEE's flagship FFD21 Aurora display, which is shown above.
