FEATuRES
• NiCu or MnCu resistive alloy;
material TCR ±10ppm/°K
• Marking epoxy UL-94-V0 confor-
mal
• 96% alumina substrate thermo
dissipation protective layer
• Cu terminal electrode Pb-free
termination
• Flame-retardant epoxy protective
coat (UL-94-V0)
• Ultra low resistance value
(0.005Ω ~ 0.050Ω); long side
electrode to satisfy the most
demanding current-sense appli-
cations.
• Precision resistance alloy
(NiCr20AlSi, or CuMnNi);
material selected for low TCR
(<50ppm/°C)
• Superior temperature coeffi-
cient characteristics; resistance
vs. temp. change from 25°C
to 125°C within 10ppm/°C ~
50ppm/°C
• Low inductance, low thermo
EMF (<50µV/°C)
