ULTRA PRECISION WIREWOUND RESISTORS
SA,MA,PC,&Q SERIES
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.
FEATURES
r Industry’s widest range of precision wirewound resistors!
r 0.1Ω to 25M, 50mW to 2W, ±.005% to 1%, TC’s to ±2PPM
r All welded construction, negligible noise, low thermal EMF
r Available on exclusive SWIFT TM delivery program!
OPTIONS
r Option ‘X’: Non-Inductive Winding (standard above 10KΩ)
