Ni1000SOT Temperature Sensor Contact temperature sensing Comply with former DIN 43760 standard Small SMD package SOT 23 Automotive qualified DESCRIPTION Ni1000SOT is a nickel thin film resistance temperature detector (RTD) that is suitable for use in contact temperature sensing. The devices are manufactured by PVD-deposition on a silicon substrate. The thin film structure is covered by a passivation layer for environmental protection and enhanced stability. The nickel elements are mounted on lead frames and encapsulated in SOT23 packages. This technology allows the production of miniature, low cost, high precision temperature sensors. The characteristics of the temperature sensor comply with the former DIN 43760 standard. It is qualified for the most demanding automotive applications (incl. exposure to hot oil) and is suitable for many more applications in harsh environments.

The temperature error caused by excessive measurement current can be calculated using: T = P/EK 2 where P = I R is the power generated by the measurement current and EK is the self heating coefficient.
