ULTRA PRECISION WIREWOUND RESISTORS RESISTORS wCOILS wDELAY LINES 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 0.1 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 10K) r Option `P': Increased Pulse Capability r Option `HS': High Speed/Fast Rise Time r Opt. `ER': Group A per MIL-PRF-39005 (MIL-R-10509 Q Series) r Matched tolerances, T.C. tracking to 1ppm/C r Dozens of additional modifications are available... special marking, positive TC, hermetic seal, 4-terminal design, etc. LD | | 1.25"min.
