PTC Electrical Component
With a positive temperature coefficient, PTC components increase their resistance as temperatures rise, ensuring precise measurements. These components excel in detecting resistance changes, making them essential for accurate humidity and temperature sensing.
Description
A basic temperature sensor that is frequently found in consumer electronics products is the NTC thermistor. Its name, which derives from the term "negative temperature coefficient," refers to the property that it changes in response to temperature fluctuations. This property is usually associated with semiconductor materials or components whose resistance decreases with increasing temperature. An NTC thermistor is essentially a temperature-sensitive resistor that shows a progressive drop in resistance with rising temperatures.
Details
There are many popular models in PTC thermal sensors, and below are a few products for a detailed introduction.
Firstly, let's talk about the KTY82 Series. Models like the KTY82/110 and KTY82/210, are renowned for their reliable availability and adaptable features.
The KTY82/110 maintains a 1 kOhm resistance at 25°C and is available in Tape & Reel or Cut Tape packaging. With a wide operating temperature range between -55°C and 150°C, it adapts well to a variety of environmental circumstances.

On the other hand, NXP USA Inc.'s KTY82/210 has a 2 kOhm resistance at 25°C and comes with TO-236-3, SC-59, and SOT-23-3 packaging options. Similar to its series counterpart, this surface-mountable device operates within the same temperature range of -55°C to 150°C and guarantees accurate temperature measurements under a variety of conditions.

Finally, the PRF18BD471QB5RB stands out as a leading product in the PTC thermistor sensor market. Murata Electronics' PRF18BD471QB5RB PTC thermocouple is a member of the POSISTOR® PRF18/21 Series. The resistance of 470 ohms at 25°C with a tolerance of ±50% is indicated by the data, and the product's operating temperature range is -20°C to 120°C. It is designed for surface mount applications and is available in a compact 0603 (1608 metric) format.
