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.

Features

• 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)
• Ultra low resistance value (0.005Ω ~ 0.050Ω)
• Precision resistance alloy (NiCr20AlSi, or CuMnNi); material selected for low TCR (<50ppm/°C)
• Superior temperature coefficient characteristics; resistance vs. temp. change from 25°C to 125°C within 10ppm/°C ~ 50ppm/°C
• Low inductance, low thermo EMF (<50μV/°C)
