Next install the PTC fuses, F1 & F2, which are installed adjacent to the power header. As with the
resistors and capacitors you've installed so far, these devices are not polarised so they can be
installed in either orientation. Use the same technique for these as for the resistors and the ceramic
capacitors, but try to avoid overheating them, as they can be damaged by excess heat.
Note that the colour and the markings of the fuses shipped in the Thonk kit may differ from the ones
pictured in this build guide.
