Z Series Bulk Metal® Z-Foil COTS resistors are configured in rectangular block with through-hole leads extending through bottom surface to minimize board space. Nominal TCR is ±0.05 ppm/°C from 0 to +60°C, down to ±0.2 ppm/°C nominal and 0.6 ppm/°C spread from -55°C to +125°C, +25°C ref. Along with tight tolerances of ±0.005% (50 ppm), products offer respective load-life stability ratings of ±0.005% and ±0.015% at 70°C for 2,000 and 10,000 hr. Resistance range is 5 Ω to 600 kΩ.
