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 RMKHT.
Vishay Sfernice research and development engineers will
be willing to support any customer design considerations.
• Temperature coefficient remains at 15 ppm/°C after long
term storage at 230 °C
• Material categorization: For definitions of compliance
