Vishay PRAHT High Temperature Resistor Arrays

Vishay Sfernice PRAHT 100, PRAHT 135, and PRAHT 182 Series Resistor Arrays are thin film wrap-around chip resistor arrays that offer high operating temperature range up to 215ºC and an industry high maximum storage temperature of 230ºC. The PRAHT 100, PRAHT 135, and PRAHT 182 Series Resistor Array networks from Vishay provide 2 ppm/ºC TCR tracking and a ratio tolerance as tight as 0.05%.  These resistor arrays also feature very low noise and load life stability of 0.7%. Vishay's PRAHT Series received a 2012 Product of the Year award from Electronic Products Magazine.
