| PRA 100, 135, 182 (CNW) Vishay Sfernice High Precision 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) * Pre-tinned terminations over nickel barrier * Lead (Pb)-free available 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 1 mm, 1.35 mm and 1.82 mm pitch.
