PRAHT 100, PRAHT 135, PRAHT 182 (CNW) www.vishay.com Vishay Sfernice High Temperature (230 °C) High Precision Thin Film Wraparound Chip Resistor Arrays FEATURES PRAHT arrays can be used in most applications requiring a matched pair (or set) of resistor elements at very high temperature up to 230 °C. The networks provide 2 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. • Tight TCR (10 ppm/°C) and TCR tracking (to 2 ppm/°C) • Very low noise < - 35 dB and voltage coefficient < 0.01 ppm/V • Ratio tolerance to 0.05 % • Gold terminations for temperature up to 230 °C • High temperature (230 °C) • SnAg terminations for temperature up to 200 °C • SMD wraparound chip resistor array • Thin film technology • Material categorization: For definitions of compliance please see www.vishay.com/doc?99912 TYPICAL PERFORMANCE TCR TOL.
