ꢀ Industry’s widest range: 0.1Ω to 25MΩ,
tolerances to ± 0.005%, TC’s to 2PPM
ꢀ All-welded, negligible noise, low thermal emf
Series SA (standard), MA (mini), PC (radial), and Q (economy) are
designed for precision circuits (DC5 and low frequency AC). The standard
construction features well-proven wirewound technology. Customized WW
and NiCr film designs are available for high-frequency operation. All
models are preconditioned thereby enabling excellent stability/reliability.
