Caddock SR20 Series
The SR20 series from Caddock are precision current sense resistors, with a resistance range from 0.005Ω to 1Ω and a maximum operating temperature of +150°C. These resistors have a maximum power rating of up to 2W (at 70°C) and tolerance of ±1.0%. The Caddock SR20 resistors offer a non-inductive design, compact footprint which minimises circuit board space, terminals are constructed for Kelvin connections to the circuit board and have the proven performance of Micronox® resistance films to achieve a low cost resistor.
