At 2%/K to 6%/K, Electrical specifications and ordering codes the negative temperature coefficients of resistance are about ten times greater than those of R DR /R B B B Ordering code 25 R R 25/50 25/85 25/100 metals and about five times greater than those of silicon temperature sensors. NTC thermis- tors are simple yet very sensitive and accurate sensing elements for measuring and control kV % K K K circuits.
