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.
• Temperature coefficient down to 15 ppm
(-55 °C; +215 °C)
• Tolerance down to 0.01 %
• Load life stability: 0.35 % max. after 2000 h at 220 °C
(ambient) at Pn
• Shelf life stability: 0.7 % typ. (1 % max.) after 15 000 h at
230 °C
• SMD wraparound
• TCR remains constant after long term storage at 230 °C
(15 000 h)
• Sulfur resistant (per ASTM B809-95 humid vapor test)
• Material categorization: for definitions of compliance

POPULAR OPTIONS
It is recommended to consult Vishay Sfernice for availability first.
Option: Enlarged terminations:
For stringent and special power dissipation requirements, the thermal resistance between the resistive layer and the solder joint
can be reduced using enlarged terminations chip resistors which are soldered on large and thick copper pads acting as heatsink
(see application note: 53048 “Power Dissipation in High Precision Vishay Sfernice Chip Resistors and Arrays (P Thin Film, PRA
Arrays, CHP Thick Film)”
www.vishay.com/doc?53048.
Option to order: 0063 (applies to size 1206 / 2010).

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
Can be filled up to maximum quantity indicated in the table
here above, taking into account the minimum order quantity.
When quantity ordered is between the MOQ and the
maximum reel capacity, only one reel is provided.
When several reels are needed for ordered quantity
within MOQ and maximum reel capacity: please consult
Vishay Sfernice for specific ordering code.
