Description
Linear PTC Thermistor (LPTC) resistance increases with the temperature rises in linearity, displays a virtually linear positive temperature coefficient over their entire temperature range, suitable in measurement and control system, temperature compensation. As the construction material is mainly semiconductor monocrystalline silicon, also called silicon temperature sensor, silicon thermistor, sometimes referred to as silistors. As the temperature coefficient is positive, the silicon temperature sensors exhibit fail-safe operation when a system overheats. Furthermore silicon is inherently stable, so silicon temperature sensor are extremely reliable and have very long operational lifetimes. Hermetically sealed glass package, axial leaded, 2 leads, can operate in high temperature and moisture environment. Linear PTC thermistor in small dimension, tightness, convenient for automatic installation.
