Notes:
*An example use for this calculator is when designing small signal amplifier bias circuits and choosing resistors for setting collector/drain current.
*Guide Calculations only, amalgamated from various chip resistor manufacturer specifications: Rohm, Yageo-Phycomp, Bourns
-Roughly 100% rating until +70DegC then linear de-rating to 0% at +155DegC.
