Linear Ptc Thermistors

We are offering clients Linear PTC Thermistors (LPTC) resistance increases with the temperature rises in linearity, displays a virtually linear temperature coefficient over their entire temperature range, suitable in measurement and control system, temperature compensation. As the construction material is mainly semiconductor mono crystalline 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.
1. Silicon temperature sensors have a TK (temperature coefficient) which is nearly constant over the complete temperature range. Temperature coefficient a25/50a Y0.7%/C.
2. Excellent long term stability, annual diversification ratea 0.01C/per year, temperature drifts during the lifetime of silicon temperature sensor are negligible.
3. Thermal Time Constant: 10 seconds max in still air.
4. Operating temperature ranges-50~+150C.
5. Dissipation factori 2.5~5mW/C.
6. Maximum operating current=1.0mA.
7. Rated poweri 10mW.
8. R25(ohm) : 600 1000, 1600, 2000.
