The RH variety is inductive. For non-inductive, you want the NH
series, which Newark and Digikey do not seem to carry. Mouser has it
at:

for twice the price.

Dump them in a bucket of water, or bolt them to a chunk of aluminium and
place a small fan on the aluminium.

An aluminum heat sink will keep my coffee warm. All the water does is
raise the humidity in the lab and create a huge mess when I tip over
the bucket. I'll take the aluminum heat sink, but without the fan,
which makes too much noise.
