High Stability - High Temperature (230 °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 215 °C powered or up to 230 °C un-powered) has leaded 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.

com/doc?53047 in conjunction with this datasheet to help them to properly design their PCBs and get the best performances of the PHT.
Vishay Sfernice R&D engineers will be willing to support any customer design considerations.
