In summary, the PLTT series are a low TCR high temperature thin film surface mount chip resistors. These resistors have a low TCR of ±5 ppm/ºC, with tolerances down to ±0.02% and are available in 0805 to 2512 case sizes. This series is constructed to perform in high temperature environments and has a wide operating temperature range of -55ºC to +215ºC. This series, due to its exceptional stability characteristics, is highly suitable for down hole precision applications in the oil and gas exploration industry.
