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 Ω 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)

 Non-inductive, non-capacitive design

 Non hot spot design

 Rise time: 1 ns effectively no ringing

 Current noise: 0.010 μVRMS/V of applied voltage (< - 40 dB)

 Thermal EMF: 0.05 μV/°C typical

 Voltage coefficient: < 0.1 ppm/V

 Thermal stabilization time < 1 s (nominal value achieved within 10 ppm of steady state value)

 Non-inductive: < 0.08 μH

 Terminal finish available: lead (Pb)-free or tin/lead alloy

 Impervious to harmful environments - oil filled

 Prototype quantities available in just 5 working days or sooner. For more information, please contact foil@vishaypg.com
