Surface Mount Package Chip NTC Thermistor 0402 0603 0805 SMD For Smartphone Tablet Automotive xEV Wearables Medical
Description
Chip NTC thermistors are thermally sensitive semiconductive resistors that are designed for temperature measurement and compensation. The portfolio covers NTC thermistors with excellent long-term stability in high-temperature and high humidity environment, e.g. for smart phone, tablet by small case size, automotive applications, LED modules and industrial applications. Tight tolerances of resistance and B value allow highly accurate temperature sensing capabilities.

Temperature characteristics
Examples
To customers who use NTC Thermistors for the first time
STEP 1:Please specify the required conditions.
①A basic constitution of circuit
②Reference voltage
③A range of temperature control and a range of an output voltage
④A target temperature and a target output voltage
STEP 2:We’ll make a table and graphs of the main characteristics value
①An output voltage(the upper and the lower limit)
②Sensitivity(mV/℃)
③Accuracy in temperature
④Current of circuit
STEP 3:We’ll change the circuit constant and simulate
①Decide the part number
(1)Ｂ value and its tolerance
(2)Resistance value R25 and its tolerance
②Simulate the resistance value of the peripheries of a fixed resistor and its tolerance
We propose you the best circuit constant.
