Temperature Sensors - NTC Thermistors
NTCLE100E3474HB0 is a Negative Temperature Coefficient (NTC) thermistor, a type of resistor whose resistance changes when subjected to a change in temperature. It is a thermally sensitive semiconductor device with a fixed negative temperature coefficient of resistance. With thermistors, a higher temperature leads to a lower resistance while a lower temperature leads to a higher and as the temperature increases the resistance of the thermistor decreases.
The NTCLE100E3474HB0 is a surface mounted device designed to be used as a temperature sensing element for a variety of applications. It is characterized by a low cost, small size and high accuracy in comparison with other temperature sensing devices. The thermistor consists of a ceramic disc embedded with a resistive material. It has an insulated lead wire attached to each side of the disc. The ceramic disc is typically formed from a sintered nickel-cobalt material with a resistance-temperature curve approximating an exponential law.
The NTCLE100E3474HB0 has a wide range of working temperatures, from -40°C to +125°C and comes with a tolerance of +/-2%. It has a broad temperature range, low thermal time constant and fast response time. It is also resistant to electrical shock and vibration and does not need to be recalibrated due to aging.
The NTCLE100E3474HB0 is a durable surface mounted device with a reverse voltage rating of up to 60 Volts and a dielectric strength of 1KV. Its typical resistance value is 4.7 ohms at 25°C making it ideal for use in a range of sensing applications.
The NTCLE100E3474HB0 can be used in a variety of application fields, most notably in heating, ventilation and air-conditioning (HVAC) systems. It can also be used in thermistors probes for industrial systems, and in many home electronics, such as ovens, air conditioners, refrigerators, washing machines, and dishwashers.
The working principle of a thermistor is based on the fact that its resistance changes with the temperature, typically in an exponential manner. When a current is applied to the NTCLE100E3474HB0, it will heat the device and cause a change in resistance. This resistance change is proportional to the temperature of the device and can be used to measure the temperature.
When the NTCLE100E3474HB0 is used as a temperature sensing element in an application the resistance value must be known at different temperatures, as the resistance is temperature-dependent. This is achieved by plotting the device’s resistance-temperature curve with data from tests. This curve is also known as dissipation factor (DF) and it exhibits a specific curve or profile for the thermistor. Calculations of temperature can then be performed by using the resistance-temperature data.
The NTCLE100E3474HB0 is a reliable and cost-effective temperature sensor that can be used for a variety of applications. It offers high accuracy, fast response and a wide range of operating temperature, making it an ideal choice for many temperature sensing applications.
