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.
• Tolerance down to 0.05 %
• Load life stability: 0.8 % typical (1 % max.) after 2000 h at
250 °C (ambient) at Pn
• Shelf life stability: 1.5 % typical after 8000 h
• SMD wraparound
• 0.02 % upon request
• TCR remains constant after long term storage at 270 °C
• Sulfur resistant (per ASTM B809-95 humid vapor test)
• Material categorization: for definitions of compliance

PACKAGING RULES
Waffle Pack
Can be filled up to maximum quantity indicated in the table
here above, taking into account the minimum order quantity.
When quantity ordered exceeds maximum quantity of a
single waffle pack, the waffle packs are stacked up on the
top of each other and closed by one single cover.
To get “not stacked up” waffle pack in case of ordered
quantity > maximum number of pieces per package:
Please consult Vishay Sfernice for specific ordering
code.
Tape and Reel
