KTY81 2KOhm Series Silicon Thermistor PTC LPTC81-210 220 221 222 250 251 252

Description Of The Silicon Thermistor PTC

- Linear PTC thermistor (LPTC) resistance increases linearly with temperature,
- It shows almost linear positive temperature coefficient in the whole temperature range, suitable for measurement and control system, temperature compensation.
- Since the structural material is mainly semiconductor single crystal silicon, it is also called silicon temperature sensor, silicon thermistor, and sometimes silicon resistor.
- Because of the positive temperature coefficient, silicon temperature sensors exhibit fail-safe operation when overheated.
- In addition, silicon itself is stable, so silicon temperature sensors are very reliable and have a long service life.
- Hermetically sealed glass package, axial lead, 2 leads, can operate in high temperature and humidity environment.
- Linear PTC thermistor, small size, good sealing, easy to install automatically.
- AMPFORT Linear PTC Thermistor (LPTC)

Application Of The Silicon Thermistor PTC

- Industrial automation control equipment, home appliance temperature detection and compensation, precision circuits and crystal oscillator temperature compensation.
- Temperature compensation for silicon semiconductor devices, temperature compensation instrumentation amplifiers, A/D converter temperature compensation.
- Micro-motor timing control, automotive temperature detection and control, medical equipment temperature detection and control.
- Linear PTC Thermistor Applications
- Also includes transmission, engine oil and coolant, heating system, overheating protection, amplifiers, power supplies, sensors, telemetry,
- Computer, magnetic amplifier, temperature measurement, weather, temperature regulation and over temperature protection.
