Description

The SMK current sensing precision resistor series from Isabellenhütte offers the designer higher power ratings and low internal temperature rises due to the larger pad termination sizes. The MANGANIN® alloy resistance element with a resistance range of 0.008Ω to 0.5Ω, has a TC of below 50ppm/°C over the temperature range of between +20°C and +60°C for resistance values of 0.015Ω or more and offers excellent long term stability. The SMK model offers these capabilities in a 1206 chip size.

  • Current sensing precision resistor
