Vishay Sfernice

High Precision Resistor Chip 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

•

High temperature option (200 °C)

•

SMD wraparound chip resistor array

•

Compliant to RoHS directive 2002/95/EC

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.
