High Precision Resistor Arrays
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.
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
Pb-free
Available
RoHS*
COMPLIANT
• Ratio tolerance to 0.01 % (R ≥ 200R)
• Pre-tinned terminations over nickel barrier
• Lead (Pb)-free available
