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.
• Tolerance down to 0.05 %
• Load life stability: 0.5 % max after 1000 h at 215 °C
(ambient) at Pn
• SMD wraparound
• Compliant to RoHS directive 2002/95/EC
