Semiconductors and thermistors

KTY sensors

Silicon sensors in the KTY series are modules with a semiconductor layer. They have a positive temperature coefficient but, unlike PTC thermistors, have a relatively linear characteristic curve. When handling or processing KTY sensors, it is essential to note that they are sensitive to electrostatic charges. It is therefore essential to take appropriate protective measures (ESD protection).
