Possibly threadjacking, but people have been mentioning cooling a shunt...
I've got a task at work which needs a pretty good shunt, and I was wondering if anyone here has any experience or comments about adding extra cooling to reduce the temperature rise. The shunts I have on hand are round cylindrical (encapsulated) types with 4 wire legs. Would blowing a fan across them be suitable, or would I risk inducing big temperature gradients and increasing the tempo and/or thermocouple effects?
The resistors I've got are Ohmite 17FPR100E (4 wire though hole, 0.1R, 7W, 50ppm, 2uV/C) and my expected currents are 3.4A, 2A and 0A.
In fact, the FHR4V-0R1F1 mentioned by NANDBlog probably would have been a better choice.
