Is NTC same as thermistor?

In general, thermistors are composed of sintered ceramics consisting of highly sensitive material with consistently reproducible properties of resistance versus temperature. NTC Thermistors are non-linear resistors, which alter their resistance characteristics with temperature.

How do I find the NTC thermistor?

Testing a PTC thermistor follows all the same steps as a NTC thermistor. First check, with an ohmmeter, the thermistor without any heat applied. With a PTC thermistor at room temperature or below, the thermistor should measure a very low resistance. Now apply heat, just like before, to the thermistor’s body.

What is the range of NTC thermistor?

Temperature Range Since NTC thermistors perform well in an operating range between -50°C and 250°C, they are well suited for a wide range of applications in many different industries.

How does thermistor NTC work?

With an NTC thermistor, when the temperature increases, resistance decreases. Conversely, when temperature decreases, resistance increases. When temperature increases, the resistance increases, and when temperature decreases, resistance decreases. This type of thermistor is generally used as a fuse.

How does NTC-based limiting work in a thermistor?

NTC-based limiting operates on the nature of the NTC thermistor to self-heat and lower its resistance. However, when a system is quickly turned off and then on again, the NTC thermistor may not have completely cooled. It takes time for the NTC thermistor to release its heat and reset, dependent upon the size and mass of the NTC thermistor.

Where can I buy a NTC thermistor sensor?

NTC thermistors are probably the most commonly used class of sensor as they are cheap, easy to use, and despite not being incredibly precise are accurate enough for most applications. If you’re looking to purchase NTC thermistors, head over to Octopart and see what’s in stock with your favorite distributor.

How does a PTC thermistor protect the inrush current?

When the previous scenarios occur, a positive temperature coefficient (PTC) thermistor can provide effective inrush current protection. A PTC thermistor functions opposite to an NTC thermistor: as temperature rises, its resistance increases. Resistance begins to increase rapidly at Curie temperature ( T c ).

What does ametherm NTC thermistor stand for?

These solid state temperature sensors actually act like electrical resistors that are temperature sensitive.  That is where the name, a clear combination of the words thermal and resistor, comes from. Ametherm specializes in NTC, or negative temperature coefficient, thermistors. Thermistors are an incredibly accurate category of temperature sensors
