FEaTURES
■
Resistance tolerance ±1% and T.C.R. ±100 ppm/K are available
■
Small in dimension and broad range in high resistance
■
Metal glaze resistor elements provide high stable performance
against environmental conditions and overload
■
The RK 1/2 G is a discharge path resistor, which is recognised by
UL 1676 and c-UL (CSA-C22.2, No. 1-M94) (File No. E159326);
EIA J RC-2128
■
Rated ambient temperature: +70°C
