Version 3 already? And this was so long ago too! I mean, with the last update being on 11th of September, it is nearly coming to seven weeks!
Anyway,
The decision to use the 1/8W Resistors
No doubt that both 0805 and the through-hole 1/8W resistors have a power rating of 0.125W, the potential issue I am looking at here is heat dissipation. The SMD resistor has very little surface area compared to its through-hole counterpart. I can implement a bigger SMD such as the 1206 (1/4 Watt) or the 1210 (1/2 Watt) to counter this problem. Another reason for the through-hole resistor is that they might help in the model’s interior detailing but then again, not many would peek inside the wheel wells…
The reverse decision to use the 1206 SMD Resistors
Well, what do you know. I’ve changed my mind again. There were a few factors which convinced me, namely:
- The 1206 SMD resistor is rated at 1/4W (or, 0.25W) which is capable of handling the part of the circuit’s 0.037W,
- I found some very much needed 1206 20 Ohm SMD resistors in my inventory cabinet, and
- I actually do not have any 1/8W through-hole resistors.
