## Ni1000SOT 

## Temperature Sensor 

## SPECIFICATIONS 

- **Contact temperature sensing** 

- **Comply with former DIN 43760 standard** 

- **Small SMD package SOT 23** 

- **Automotive qualified** 

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

## SELF HEATING EFFECT 

For accurate temperature measurement it is recommended to choose a small current to avoid self heating of the nickel sensing element. The temperature error caused by excessive measurement current can be calculated using: T = P/EK 

where P = I[2 ] ∙R is the power generated by the measurement current and EK is the self heating coefficient.

## ELECTRICAL CHARACTERISTIC 

The characteristic of the nickel temperature sensor is specified as per DIN 43760. The large Temperature Coefficient of Resistance (TCR) of the Ni-RTD, 6178 ppm/K, offers greater sensitivity than other types of RTD’s. The electrical characteristic can be described by the following equation: 

## **R(T) = R0 (1+aT+bT[2] +cT[4] +dT[6] )** 

Coefficients: a = 5.485 x 10[-3 ] b = 6.650 x 10[-6] c = 2.805 x 10[-11] d = -2.000 x 10[-17] 

**T(R) = a´+b´(1+c´R)[½ ] +d´R[5] +e´R[7 ] dT < 0.12 K (higher order equations on request)** 

Coefficients: a´= - 412.6 b´= 140.41 c´= 0.00764 d´= - 6.25 x 10[-17] e´= -1.25 x 10[-24] **Tolerances** : Class B  (0.4+0.007 x |T|) in range from 0[o] C to +160 °C  (0.4+0.028 x |T|) in range from -55[o] C to 0 °C
