Description:
The 100K OHM Thermistor – Pack of 5 is a set of Negative Temperature Coefficient (NTC) resistors that offer precise temperature sensing by decreasing resistance as temperature increases. Commonly used in 3D printers, battery packs, thermostats, and other environmental monitoring systems, these thermistors provide an affordable and accurate analogue temperature sensing solution that can be easily interfaced with microcontrollers and analogue-to-digital converters.
With a nominal resistance of 100KΩ at 25°C and a typical Beta value of 3950K, these thermistors are highly sensitive over a broad temperature range. They are housed in a compact epoxy-coated or glass bead format and come with axial leads for easy through-hole mounting on PCBs or breadboards. Their simple 2-wire design requires only a voltage divider circuit to produce accurate temperature readings, making them ideal for both beginners and professionals in embedded systems, IoT projects, or thermal control applications.
