NTC Key benefits Accurate, passive temperature sensing using a negative temperature coefficient element that reliably decreases resistance as temperature rises Simple integration into analog or digital measurement circuits for fast, lowcost temperature feedback Compact form factor that fits tight spaces and is compatible with both leaded and surfacemount PCB assemblies Robust, longterm performance suitable for monitoring, control, and protection tasks What it does Functions as a temperaturedependent resistor (thermistor) with a negative temperature coefficient, providing a predictable change in resistance with temperature Converts temperature changes into an electrical signal that can be read by microcontrollers, ADCs, temperature controllers, or comparator circuits Can be used for sensing, compensation, or inrush current limiting depending on circuit design Compatibility and installation Works with common electronics platforms and control systems that accept resistive temperature inputs Compatible with analog measurement chains (voltage dividers, bridge circuits) and digital systems using ADCs and simple calibration Available in compact packages suitable for direct PCB mounting or placement in sensor housings; choose the package and lead style that match your assembly process Material and performance notes Typically constructed from metaloxide ceramic materials that provide stable, repeatable resistance change with temperature Offers sensitivity to temperature changes, low power consumption when used in sensing circuits, and good longterm stability when properly specified and installed Performance depends on the specific resistance value at reference temperature and the thermistor's characteristic curve; select the correct part to match your measurement range and accuracy needs Practical applications Battery pack monitoring: place near cells to detect elevated temperatures and trigger charging or protection circuits to prevent overheating HVAC and environmental sensing: integrate into thermostats, vents, or enclosures for accurate ambient temperature measurement and control Power electronics protection: use as part of an inrush current limiting circuit or temperaturecompensation network to protect components during startup and operation Choosing and using the right NTC Match the nominal resistance and temperature characteristic to your sensing range and the input requirements of your measurement system Consider package size, thermal contact, and response time for reliable readings in your intended environment Use appropriate calibration or lookup tables to convert resistance to temperature for higher accuracy Reliable, compact, and straightforward to use, the NTC is a practical component for temperature measurement, compensation, and protection in a wide range of electronic applications.
