Ohmite Manufacturing has extended its range of metal element, SMD, current sense resistors with the release of the MCS product range. These 1 and 2 watt packages are stocked in 1% tolerance with resistance values from 0.005 – 0.050 ohms. Using nickel-chromium and manganin-copper alloys, MCS Series offers low TCR, inductance, and thermo EMF benefits. Highly efficient manufacturing processes enable outstanding performance is coupled with a very competitive cost.


• NiCu or MnCu resistive alloy; material TCR ±10ppm/°K
• Marking epoxy UL-94-V0 conformal
• 96% alumina substrate thermo dissipation protective layer
• Cu Terminal Electrode with Pb Free termination (60% Sn, 40% Ni)
• Flame-retardant epoxy protective coat (UL-94-V0)
