FEATURES

? Temperature coefficient of resistance (TCR): ± 0.2 ppm/°C typical (- 55 °C to + 125 °C, + 25 °C ref.). For ultra high performances (instrumentation and metrology) please refer to the last page

? Resistance range: 5 ? to 1.1 ? (higher or lower values of resistance available)

? Foil resistors are not restricted to standard values; specific “as required” values can be supplied at no extra cost or delivery (e.g. 1K2345 vs. 1K)

? Power coefficient “?R due to self heating”: 5 ppm at rated power with the Z-Foil technology

? Tolerance: to ± 0.001 % (10 ppm)

? Load life stability to ± 0.002 % (20 ppm) at 25 °C, 2000 h at rated power

? Load life stability, can be considerably improved through in-house stabilization

? Shelf life stability: 2 ppm for at least 6 years (unaffected by humidity)

? Electrostatic discharge (ESD) up to 25 000 V

? Power rating: 0.3 W to 2.5 W at + 25 °C (depending on model - see table 2)
