Ultra Precision Bulk Metal® Foil Resistors


There is No Alternative!






The industry’s lowest temperature coefficient of resistance (TCR),
and power coefficient (PCR).



Bulk Metal foil resistors deliver proven reliability and stable performance.

(Even when exposed to unstable levels of temperature
and humidity or other harsh environmental conditions.)


Key features:


  • “Zero TCR”: ±0.2 ppm/°C (MIL range) with Z-Foil technology
  • TCR tracking: to 0.1 ppm/°C
  • PCR (power coefficient): 5 ppm typical at rated power for Z-Foil resistors
  • Load-life stability under applied power:

– 0.005% (50 ppm) over 2,000 hours at 70 °C

  • Resistance range: any value from 2 mΩ to 3.3 MΩ (for higher and lower values, please contact us)
  • Tolerance: absolute and match for voltage dividers and networks: to ±0.001 %
  • 4-terminal connections for low values
  • Low current noise: – 40 dB
  • Thermal EMF: 0.05 μV/°C
  • Voltage coefficient: <0.1 ppm/V
  • Non-inductive: <0.08 μH
  • Rise time: 1 ns without ringing
  • Lead (Pb)-free and RoHS-compliant available upon request


Resistors | Decade Boxes | Standard Resistors | Shunts


The ultra precision resistors, the rotary switches, the output terminals and the
double shielded construction are all features of the 6-Dial Decade Resistance Box
with 6-1/2 digit readings.
