High Temperature (230 °C) High Precision
Thin Film Wraparound Chip Resistor Arrays
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.
FEATURES
• 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
