MCS SMD Metal Element Current Sense Resistors Ohmite MCS SMD Metal Element Current Sense Resistors utilize resistive metal alloy mOhm technology. The MCS resistors from Ohmite also offer a 96% alumina substrate thermal dissipation protective layer, a Cu terminal electrode with lead-free termination (60% Sn, 40% Ni), and ultra-low resistance values from 0.005Ω to 0.05Ω. The MCS resistors have power ratings of 0.75W, 1W, and 2W and standard resistance values from 5mΩ to 50mΩ. These resistors are utilized in industrial electronics and power electronics.
