Temperature Sensors - NTC Thermistors

NTCLE305E4202SB is a temperature sensing device that is based on an NTC (Negative Temperature Coefficient) thermistor. The thermistor is a variable resistor whose resistance is inversely proportional to temperature.

The operation of a thermistor is based on the change of electrical resistance when the temperature varies. NTCLE305E4202SB is a thermistor with a standard 10Kohm NTC resistance. The device has a wide range of resistances from 1Kohms to 100Kohms, depending on its operating temperature.

It features a built-in temperature range of -10°C/+85°C. It also offers a wide tolerance over the entire temperature range, covering a range of ±2% to ±5%. NTCLE305E4202SB has a very low noise output with a maximum of 2 millivolts for temperatures over +50°C.

NTCLE305E4202SB is a high-precision and cost-effective device used for temperature sensing applications. Temperature control systems use it for temperature regulation, while in other applications, it can be used to monitor temperatures in refrigerators, stoves, and even ovens. It is also often seen in medical applications, where temperature control is required.

The working principle of NTCLE305E4202SB is based on the semiconductor theory of electron movement. When a voltage is applied to the device, electrons migrate across the thermistor material from the n-type silicon (which is positively-charged) to the p-type silicon (which is negatively-charged). The movement of the electrons causes some of the electrons to become stuck in the thermistor material, which then changes the device’s resistance.

The amount of electron movement is determined by the temperature, and the resistance changes inversely with the temperature. When the temperature rises, more electrons are stuck in the thermistor, causing its resistance to decrease. On the other hand, when the temperature drops, the number of electrons stuck in the thermistor material decreases, thus increasing its resistance.

NTCLE305E4202SB is a temperature sensing device that can be used for a wide variety of applications. It is a cost-effective solution with a high degree of accuracy and reliability. It is suitable for both industrial and medical applications, making it a suitable choice for a range of temperature-sensing needs.
