PRA074 Datasheet | Vishay

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 d B 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 pliance please see .vishay./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.
