What is the right-most component in this picture?

$begingroup$


enter image description here



I'm reverse engineering an old RF transmitter circuit and I can't seem to figure out if the right-most component is a 3 band resistor (+/- 20%) or a capacitor (as the label on the board would indicate).



If it is a resistor, my best guess is that it is 380 ohms. Otherwise, I'm completely at a loss.

    Looks like 47 pF to me. Yellow Violet Black

    Highly unusual value and very high too for such a small component. If you read it backwards it’s 47 pF, mush more reasonable.

    Do small disc capacitors really come in this shape? I can't find any pictures like it elsewhere. It looks like half a resistor, rather than a disk.

    $begingroup$
    @Yoshiyahu Only you can tell the color accuracy, but 380 pF is still resonable for such a physically small capacitor, although 47 is far more common than 380. 47 is in the E12 series and 380 requires E24. Your board looks one-layer Pertinax which does not ryme well with E24, but not impossible. Measure it with an LCR meter to tell for sure!
