I bought some of these, but i have one big problem. Cant find datasheet. I find only some characteristics thats really confuse me. http://www.radiolamp.ru/sprav/ind/iv3a.html

I need help to understand this thing. I need 30V voltage on a segment? And I cant understand what current I need?

BTW This is my first project with nixies

 

pin 9 is the plate (ie: anode)
pins 8 and 7 are the filament; 8 is also something else. Grid?

P: 1 2 3 4 5 6 10 11 (P=pin numbers, digits follow)
0: x x   x x x  x
1: x            x
2: x x x   x x
3: x x x     x  x
4: x   x x      x
5:   x x     x  x
6:   x x x x x  x
7: x x          x
8: x x x x x x  x
9: x x x x   x  x
,:                x  (comma)

IH, 50+5mA Something to do with the heater; odd way of writing it.
IaZ 0,5mA (I'm guessing that's the period)
Ic, 3mA (not sure if this is total current, or maximum plate current)
250-500, 200 (Seems high for voltages)

If it were a 7-segment LED display, the pins would compare to:
pin 1 = b
pin 2 = a
pin 3 = g
pin 4 = f
pin 5 = e
pin 6 = d
pin 10 = c
pin 11 = DP (the comma)
pin 9 is the common anode.

The display is reported to be green.

 

Well, there IS some information out there, if you can only read Russian.
Yours is covered ((I think; Russian text) in this .pdf:

nice find, 7 segment nixies aren't very common.
like SgtWookie said, the pins 1,2,3,4,5,6, and 10 each light up a segment, 11 is a decimal.

Wookie's probably right, but when I looked at it, the first thing I thought was that 7&8 were the anode and 9 was the grid, but I'm not sure.

If it doesn't work one way, try another. Nixies are surprisingly hard to mess up as long as you limit your current.

(life would be so much easier if someone on here read russian...)
