Typical resistance @25C 15 ohm, 100 ohm, 200 ohm, 500 ohm, 1k ohm, 2k ohm,3k ohm, 4k ohm, 5k ohm, 10k ohm, 15k ohm, 20k ohm, 30k ohm, 47k ohm, 50k ohm, 100k ohm, 200k ohm, etc.
Resistance tolerance can be 5%, 10%, 20%.
Rated power 0.5W.
Operating temperature: -55C--+125C.

 

Description:

 

Since all metals used for coil windings have a positive temperature coefficient of resistance, NTC thermistors are especially useful for compensating resistance changes in devices subjected to temperature variations. Due to the high temperature coefficient of the thermistor as opposed to the low temperature coefficient of the copper, full compensation can be achieved by using a thermistor- resistor network. This network adds less than 15% to the total impedance of the circuit. Compensation of transistor amplifiers, crystal oscillators, etc. can be achieved by using similar methods.

 

 

Applications:

 

Temperature compensation in electronic circuit. 
Temperature compensation of meter,instrument and other computation equipment. 
Temperature compensation of instrumentation winding coil, integrated ciruicts, crystal oscilliator. 
Temperature measurement and control which do not have very high accuracy requests.

temperature compensation circuit of LCD Liquid crystal displays using NTC thermistor as temperature sensor 

Schematic drawing of a temperature compensation circuit of Liquid crystal displays (LCDs) using NTC thermistor as temperature sensor
For Liquid crystal displays LCD modules often a temperature compensation circuit is used, consisting of NTC thermistors and resistors. The thermistor as main temperature-sensitive device with its characteristic resistance temperature curve provides a high driving voltage in the cold and a low driving voltage in the hot temperature region, compensating in this way the LCD temperature characteristic.
