PVHT0402

www.vishay.com PVHT Vishay Sfernice High Stability - Very High Temperature (270 °C) Thin Film Wraparound Chip Resistors, Sulfur Resistant INTRODUCTION For applications such as down hole applications, the need for parts able to withstand very severe conditions (temperature as high as 250 °C powered or up to 270 °C un-powered) has led Vishay Sfernice to push out the limit of the thin film technology. Designers might read the application note “Power Dissipation Considerations in High Precision Vishay Sfernice Thin Film Chip Resistors and Arrays (P, PRA etc…) (High Temperature Application)” www.vishay.com/doc?53047 in conjunction with this datasheet to help them to properly design their board and get the best performances of the PVHT. Vishay Sfernice research and development engineers will be willing to support any customer design considerations.
