VISHAY Intertechnology, represented by Braemac , has released the PRA 100, PRA 135, and PRA 182 resistor arrays. They have a combined relative error of less than 0.03% in sets of up to eight resistors of varying ohmic values.
They also have a TCR of 10ppm/°C and TCR tracking of 1ppm/°C. They offer a ratio tolerance as tight as 0.01%, noise of -35dB, and a voltage coefficient of 0.01ppm/V. Applications include amplifiers, oscillators, attenuators, couplers, and filters in instrumentation, calibration, and data conversion systems.
