2R Resistor

      The 2R resistor network is designed to be the designers first choice for ultra high precision, stable and reliable voltage divider or network.A significant reduction of the resistive components sensitivity to ambient temperature variations (TCR) and applied power changes, self-heating(PCR) have been made with help of the Z-Foil technology.
      2R resistor  has many features.The first one is that resistance range would be from 1 to 150K(Any ohmic value ratio is available within resistance range).The second one is non inductive/capacitive design.The third one is low temperature coefficient of resistance (TCR) absolute:± 0.05 ppm/°C (Industrial range) and ± 0.2 ppm/°C (MIL range), tracking 0.1 ppm/°C.The fourth one is power coefficient "R due to self heating": 5 ppm at rated power.The fifth one is tolerance: absolute and resistance match to 0.005%.The sixth one is resistance ratio stability: at 0.05W @ + 25°C to 0.001%.The seventh one is electrostatic discharge (ESD) above 25 000 Volts.The eighth one is short time overload 0.002%.The ninth one is power rating at + 125°C: 0.3W.The tenth one is thermal EMF: 0.05V/°C.The eleventh one is non hot spot design.The twelfth one is current noise: < - 40dB.The thirteenth one is rise time: 1ns without ringing.The fourteenth one is non inductive: < 0.08H.The fifteenth one is voltage coefficient < 0.1 ppm/V.The sixteenth one is for better performances please contact us.The last one is terminal finishes available:Lead (Pb)-free and Tin/Lead alloy.
      There are also some applications about 2R resistor .The first one is instrumentation amplifiers.The second one is bridge networks.The third one is differential amplifiers.The fourth one is military,airborne and space.The fifth one is EB applications.The sixth one is down-hole (high temperature).The seventh one is medical.The last one is automatic test equipment (ATE).
      Some typical performance characteristics have been concluded into several points as follow.The max ambient temp. at rated wattage would be + 125 °C.And the max ambient temp. at zero power would be +175°C.Also the insulation resistance would be > 104M.The dielectric withstanding voltage would be no change.For more information about 2R resistor  please contact us.
