This component smoked when I turned on a decades idle spectrum analyzer (Zonic+AND 3524 of 1990s vintage in like-new condition, visually) to see if I could use it for a field test. The company is no longer active and I have two giant user’s manuals but no maintenance info.
The component has a teardrop, rough-surface, dipped epoxy appearance with “10” and under that “35,” and “+” near one lead but no other I.D. It stands 3/8" above the board. The silk screen on the circuit board says, “C9,” but has an unusual (to me) symbol for a capacitor. The two parallel lines of the capacitor symbol have three diagonal cross-hatches between the lines, as shown in the photo.
I assume that this is a 10uF 35V tantalum cap and that the cross-hatches indicate some kind of transient voltage suppression in the device (the component goes from a trace to ground), but I can’t find the symbol on-line and am reluctant to simply substitute a common tantalum capacitor until I know what the symbol means. There are other identical components with the same symbol on the board and many capacitors with the ordinary capacitor symbol lacking the cross-hatching.
Any assistance appreciated.
