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.
