Through hole current shunt?
Yep. 6 milli-ohm, NiCr; from the Bosch motor control project ;-)

...Jim Thompson

IRC makes them too, little omegas (appropriate, huh?) made out of
manganin, surface mount. We make our own current shunts for our NMR

with tricky top-secret shapes.

Joking or eddy?

Manganin is the pits to machine... gums up the tooling.
