Which is better NTC or PTC thermistor?
For an NTC thermistor, as temperature increases, resistance decreases. For a PTC thermistor as temperature increases, resistance increases.
What’s the difference between PTC and NTC?
PTC stands for positive temperature coefficient and NTC is negative temperature coefficient. An NTC’s resistance will decrease with temperature; where as, the resistance from PTCs will increase. Regardless of which thermistor is being used, it is important that the devices be tested prior using.
How do I know my NTC and PTC thermistor?
NTC thermistors are thermistors whose resistance decreases when the temperature it is exposed to increases. So if heat is applied to a NTC thermistor, its resistance will drop accordingly. PTC thermistors are thermistors whose resistance increases when the temperature it is exposed to increases.
What are PTC & NTC thermistors?
Both negative temperature coefficient (NTC) and positive temperature coefficient (PTC) thermistors’ values change as a result of temperature but impact their use differently. For NTC thermistors, as temperature increases, the resistance drops from high to low and allows current to pass through.
Which thermistor is best?
NTC thermistors are frequently used due to their very low price point, but they deliver low accuracy at temperature extremes. Silicon-based linear thermistors provide higher performance and high accuracy across a wider temperature range, but this typically comes at a higher price point.
Why do we use NTC thermistor?
NTC thermistor probes are generally used as resistance thermometers. They are extremely versatile and accurate, which makes them ideal for a wide variety of applications that measure temperature. Thermistor probes work especially well for lower range of temperatures.
How many types of NTC are there?
There are two types of thermistors: Negative Temperature Coefficient (NTC) and Positive Temperature Coefficient (PTC). With an NTC thermistor, when the temperature increases, resistance decreases.
How does PTC and NTC work?
There are two types of thermistors: Negative Temperature Coefficient (NTC) and Positive Temperature Coefficient (PTC). With an NTC thermistor, when the temperature increases, resistance decreases. Conversely, when temperature decreases, resistance increases. This type of thermistor is used the most.
How accurate is a NTC thermistor?
Accuracy: NTC thermistors are highly accurate through incremental changes within their operating range. Small temperature changes reflect accurately due to large changes in resistance per °C.
What are the two main types of thermistor?
There are two types of thermistors: Negative Temperature Coefficient (NTC) and Positive Temperature Coefficient (PTC).
Where are PTC thermistors used?
PTC thermistors are widely employed as temperature sensors in electrical machines to monitor winding temperature.

What is the difference between PTC and NTC resistors?
PTC stands for positive temperature coefficient and NTC is negative temperature coefficient. An NTC’s resistance will decrease with temperature; where as, the resistance from PTCs will increase. If the change in temperature is not smooth, you might not have a properly functioning thermistor.
What is the meaning of NTC thermistor?
NTC Thermistor Definition An NTC thermistor is a thermally sensitive resistor for which the resistance exhibits a large, precise and predictable decrease as the core temperature of the resistor increases over the operating temperature range. Characteristics of NTC Thermistors
