## Chip Resistor De-rating calculator

Choose the Package size, Max Operating temperature and desired resistance value.The calculator will return the maximum current allowable with its corresponding available volt drop.

R(Ω) |
Temperature(DegC) |
Current Volt Drop |

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.
