Description
The NTC Thermistor 10K (103) is a highly accurate negative temperature coefficient thermistor designed for precise thermal sensing and temperature compensation circuits. As temperature rises, the electrical resistance of this thermistor decreases predictably, making it an essential component for microcontrollers, egg incubators, 3D printer heat beds, and HVAC systems.

❓ Frequently Asked Questions
Q1: What is the resistance of an NTC Thermistor 10K at room temperature?
The NTC Thermistor 10K has a nominal electrical resistance of 10,000 Ohms (10k Ω) at standard room temperature of 25°C.
Q2: How does an NTC Thermistor 10K work with Arduino?
An NTC Thermistor 10K works with Arduino by placing it in a voltage divider circuit with a fixed 10k resistor; the Arduino reads the analog voltage output and converts it to temperature using the Steinhart-Hart equation or B-parameter formula.
Q3: What does the code ‘103’ mean on a thermistor?
The code ‘103’ on a thermistor represents its resistance rating: ’10’ followed by 3 zeros, which equals 10,000 Ohms or 10k Ohms at 25°C.
