PRA073, PRA074, PRA100, PRA135, PRA182 (CNW) www.vishay.com Vishay Sfernice High Precision Thin Film Chip Resistor Arrays FEATURES High stability passivated nichrome resistive layer 0.02 % on ratio, 1000 h at Pn at + 70 °C Tight TCR (10 ppm/°C) and TCR tracking (to 1 ppm/°C) Very low noise < - 35 dB and voltage coefficient < 0.01 ppm/V Ratio tolerance to 0.01 % (R  200R) High temperature (230 °C) version see PRA HT ESA qualified version see PRA HR SMD wraparound chip resistor array Thin film technology Option to withstand humidity test of AEC-Q200 Material categorization: For definitions of compliance please see www.vishay.com/doc?99912 PRA arrays can be used in most applications requiring a matched pair (or set) of resistor elements. The networks provide 1 ppm/°C TCR tracking, a ratio tolerance as tight as 0.01 % and outstanding stability. They are available in 0.7 mm, 1 mm, 1.35 mm, and 1.82 mm pitch.
