PRAHT 100, PRAHT 135, PRAHT 182 (CNW) www.vishay.com Vishay Sfernice High Temperature (230 °C) High Precision Thin Film Wraparound Chip Resistor Arrays, Sulfur Resistant 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 pitch: • 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 Available • High temperature (230 °C) • SnAg terminations for temperature up to 200 °C Available • 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 please see www.vishay.com/doc?99912 TYPICAL PERFORMANCE • 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) TCR TOL.

Depending on infomation needed a compromise has to be found. A codification can be used to identify case size + configuration and number of resistors. See table below. E.g. PRAHT100I4-4K75BWGTA (Part number has more than 18 digts): PRAHT100I4 must be replaced by PRAHT17 = PRAHT17-4K75BWGTA (2) When the last digit(s) of the ohmic value is (are) 0, it (they) can be omitted. E.g.: PRAHT100I4-2K20BWGT can be ordered under PRAHT100I4-2K2BWGT PRAHT100I4-1K00BWGT can be ordered under PRAHT100I4-1KBWGT (3) N termination for temperature up to 200 °C.
