Burroughs B4998  
Written by Accutron on 2017-03-20  

With an envelope measuring only 15x10mm, the Burroughs B4998 is the smallest Nixie tube ever manufactured. The B4998 has the same 8mm digit height as the B4021, but the rectangular envelope reduces the tube's overall size and permits tighter horizontal stacking installations.

While the B4998 is impressively tiny, the integrated BIPCO driver module for this tube is surprisingly large, yet physically proportioned in such a way as to not undermine the small display area potential of the B4998.
