Effective Series Resistance- namely, the impedance of the cap at a given
frequency.  "Low ESR" is a good thing.  I've never seen it in an ad for
plastic film capacitors though, only on aluminum electrolytics and
tantalums- neither of which are suitable for TC work.

What's the Newark stock number?

Working Volts DC, as contrasted with a test or maximum allowable voltage
rating.
