Max. voltage is determined by E= (PR)½ , E not to exceed the value listed
Series SA (standard axial), MA (mini), and PC (radial lead) are
designed for critical-use functions, such as military & space
applications. Series Q economy) are designed for slightly less
demanding applications. Series PC & Q are often utilized to replace
metal film and foil resistors, and offer greater overload capability as
well as lower costs. All models receive preconditioning thereby
enabling exceptional stability and reliability.

POWER DERATING:
Series SA/MA/PC40 resistors shall be derated
according to Curve A, Series Q & PC451 per Curve B.
The power
rating of resistors with 0.1% or tighter tolerance shall be reduced 50%
(per Mil-Std-199).
