Thermistor on board (Any valve from 100 ohm-100K ohm)

The thermistor mounted on board is a temperature-sensitive resistor whose electrical resistance varies significantly with temperature. It is commonly used in temperature sensing, control, and compensation applications due to its precision and rapid response.

Key Features

Functionality: Acts as a resistor that changes resistance with temperature changes, either decreasing (NTC type) or increasing (PTC type) resistance as temperature rises.

Sensitivity: High sensitivity allows precise detection of temperature variations ranging typically from -55°C to +150°C or more depending on the type.

Accuracy: Standard thermistors may have an accuracy of ±0.2°C, while specialized sensors achieve even tighter tolerances.

Construction: Small, bead or disc-shaped sensing element mounted on a board for stable connectivity and easy integration into circuits.

Operating Voltage and Power Rating: Usually low power consumption, requiring bias currents in microampere ranges to avoid self-heating which would skew temperature measurements.

Response Time: Very fast thermal response, typically a few seconds in air, faster when in contact with liquid or thermally conductive surfaces.

Applications

Widely used in electronic thermostats, temperature controllers, HVAC systems, and medical devices for accurate ambient or device temperature monitoring.

Employed in temperature compensation circuits and as sensors in various industrial and consumer electronics.

Ideal for educational and laboratory experiments studying temperature electrical behavior.

The thermistor on board represents a reliable, sensitive, and efficient temperature measurement element suited for a broad range of temperature-dependent electronic applications.
