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.

SPECIAL FEATURES
Resistance values can be different on a given network
(R max./R min. as high as 300). Tooling charges might
be required depending on the ohmic values in the
same network. Please, consult VISHAY SFERNICE for
ohmic values, tolerances and also temperature coefficient
(e.g. ± 1 ppm/°C) outside the standard range.
