This appears to be a 1/4 Watt resistor at high magnification, and if you connect across 12V, it will draw 0.5X0.5X24= 6 Watts! Briefly.

Don't hold it in your hand while you do this, because it will quickly become incandescent, then - if the flameless type of metal film resistor - it will turn color and die.

What did you need to use it for?
