The RNC90Z family of military established reliability foil resistors has a resistance range up to 121 KW with a low TCR of 2.0 ppm/°C. The RNC90Z resistors are military-qualified to MIL-PRF 55182/9 with characteristic "Z" limits. The devices have a resistance range of 100 W to 121 KW, in addition to standard resistance tolerances from ± 1.0% down to ± 0.01% and low TCR values over an extended temperature range of 55°C to +175°C. Power rating is 0.6 W at +70°C and 0.3 W at +125°C, with a maximum working voltage of 300 V.
