How to see the resistance value on NTC thermistor? For example: 47D-15, what is the resistance value?
October 10, 2021
Look at the resistance value on the NTC thermistor: the front is the resistance value, and the back is the size diameter.
For example: 47D-15, 47 is 47 ohms, D-15 is 15 mm in diameter.
Negative temperature coefficient thermistor, also known as NTC thermistor, is a sensor resistance whose resistance value decreases with increasing temperature. It is widely used in various electronic components, such as temperature sensors, reversible fuses and automatically adjustable heaters.
Terminology of NTC negative temperature coefficient thermistor:
Zero power resistance RT (Ω)
RT refers to the resistance value measured at a specified temperature T with a measurement power that causes a change in resistance value relative to the total measurement error to be negligible.
