PHT
Vishay Sfernice
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.vishay.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.
