High Temperature (230 °C) High Precision

Thin Film Wraparound Chip Resistor Arrays, Sulfur Resistant

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 pitch:

• 1.00 mm for PRAHT 100 (based on case 0603)

• 1.35 mm for PRAHT 135 (based on case 0805)

• 1.82 mm for PRAHT 182 (based on case 1206)

FEATURES

• Tight TCR (10 ppm/°C) and TCR tracking

(to 2 ppm/°C)

• 2 to 4 resistors (same or different values)

• 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

• Very low noise < -35 dB and voltage coefficient

< 0.01 ppm/V

• Sulfur resistant (per ASTM B809-95 humid vapor test)

• Material categorization: for definitions of compliance
