metrology resistorsVishay Intertechnology announced a series of metrology and laboratory ultra-high-precision Bulk Metal Z-Foil resistors built using Z1-Foil technology that features desirable accuracy, stability, and fast thermal stabilization in sizes small enough for permanent assembly in operational equipment. The devices feature a TCR of ±0.5 ppm/°C maximum (+25°C to +125°C), tolerances to 0.005 percent (50 ppm), load-life stability of 0.005 percent (50 ppm) at + 70°C for 10,000 hours, and PCR (?R due to self-heating) of ± 5 ppm at a rated power of 0.6 W at +70°C and 0.3 W at + 125°C.
