What component is this?

I found these components the other day while looking for NTC thermistors. I grabbed a couple since the shape was similar, and thought maybe the bars indicated resistance at room temperature.

However, both of them act as an open circuit - no connection between the legs. Capacitor tester reports 0nF.

Anyone know what these are? The discs are a little less wide than my thumb.

I think they are capacitors. The left one 36pF and the right one either 360pF or 3.6nF, but since your tester reports 0nF it is 360pF, assuming your tester does not measure these low values.

This based on what the following site shows.

It really doesn't look like any capacitor I've ever seen, so if they are not NTC's my guess would be varistors (VDR's) so you would need a high voltage to get it to react.

Edit 2: VDR Color code: https://frank.pocnet.net/other/Philips/ColourCodeRC1966.pdf

Not your colors but maybe different manufacturer/series.

Yes I would also say these are varistors.

Thanks! Yes, that seems to match. Tried to measure pF capacitance, got 50-70pF so that rules out it being a capacitor (at least based on the color codes).

Wondering what interesting projects I could use these in
