AMWEI Linear Silicon PTC Thermistor Temperature Sensors, axial glass DO35 package, KTY84 83 81 substitute, resistance increases with the temperature rises in linearity, suitable in measurement and control system, temperature compensation.
Linear PTC Thermistor 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,Dumet wire, 2 leads. Linear PTC thermistor in small dimension, tightness, convenient for automatic installation.
