- Isabellenhütte 50ppm/K 0.5? resistor (probably shunt? notable as the manufacturer Isabellenhütte seems to be little known)
maybe i your world.... talk to anyone doing precision power electronics and needing heatsink mounted To220 or TO247 boady resistors with 2 or 4 terminals and the first thing they will point you to is IsabellenHutte.
Yes, that would be the mA range shunt. 0.5W is too much for A range. I'm more curious, what metal they used for the A range, and what the specification might be.
