Frequently Asked Questions

Q: How fast do NTCs respond?

A: Response time is defined as the time it takes to reach 62% or a new temperature, and is a function of mass. The smaller the sensor the faster the response. A discrete sensor will respond faster than the same sensor packaged inside a metal housing. Typical response times for a Series I NTC thermistor sensor is <15 seconds.


Q: Are NTCs available in a smaller size?

A: Typical size for an epoxy coated discrete in an OD of 0.95" Max.  Miniature glass sensors have a max. OD of 0.15".


Q: How stable are NTC sensors?

A: Different sensor famalies have different stabilaty ratings.  Epoxy coated NTCs are less stable than a hermeticlly sealed glass NTC sensors.
