100K Ohm NTC Thermistor Resistor

Small in size, high-powered, and very capable of bringing down the surge current
High in B value and low in residual current
Long service life and high reliability
High coefficient of safety and a wide range of application
Temperature coefficient: -25℃~90℃

This is a 100K ohm Negative Temperature Coefficient (NTC) thermistor.
NTC Thermistor is one of the most commonly used temperature sensors. In an NTC the resistance value decreases as the temperature increases.
This is used in 3-d printer and other appliances
