VishaySfernice Thin Film division holds ESCC QML qualification (ESCC technology flow qualification). PRA Hi-Rel arrays can be used in most applications requiring a matched pair (or set) of resistor elements. The networks provide 3 ppm/°C TCR tracking, a ratio tolerance as tight as 0.05 % and outstanding stability. They are available in 1 mm, 1.35 mm, and 1.82 mm pitch.
Applications
Thin film technology
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 (3 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
ESA/ESCC qualified
ESCC 4001 (generic specification)
ESCC 4001/025 (detailed specification)
SMD wraparound chip resistor array
Up to eight different ohmic values (CNW HR)
Suitable for military use
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 outside the standard range.
