The SMR1DZ and SMR3DZ Z-Foil molded surface-mount resistors from Vishay include thermal stabilization time of less than one second. The devices provide a low typical TCR of ±0.05 ppm/°C from 0°C to 60°C, 25°C Ref, and ±0.2 ppm/°C from -55°C to 125°C, 25°C Ref., tolerances to ±0.01%, load-life stability of 0.005% (50 ppm) at rated power for 2000 hours at ±70°C, and end-of-life tolerance to less than 0.1%. The devices offer a resistance range of 5 O to 80 kO. From $4.70.
