Introduction

NTC Thermistors are temperature sensors which have been used ubiquitously across industries ranging from automotive to medical applications. They are thermistors – resistors that thermally- dependant – meaning that they are sensitive to slight variations in temperature. The B57352V5104F360 is a thermistor from the NTC family that is popular among engineers for its accuracy and reliability, and commonly used in temperature sensing applications.

Electrical Characteristics

The B57352V5104F360 features its fairly low resistance values over a wide temperature range of -40°C to +125°C. The cutting point of the thermistor is determined by the nominal resistance value at 25°C (R25), which is 5100 ohms. The Particular curve coefficient (B value) is built into the device; with B=3470 and To = 25°C. Its resistance value can be measured by using an ohm meter.

Applications

Due to its rapid response time and accuracy, the B57352V5104F360 is ideal for applications that require temperature measurements. Common applications of the unit can be found in various automotive systems, such as climate control, test equipment, and accurate temperature sensing for aviation , aerospace, and nuclear power systems. It is also used in medical and laboratory applications where varying temperatures have to be monitored.

Working Principle

When a voltage is applied to a thermistor, the current flow across it increases as the temperature of the thermistor rises. This is due to the change in the electrical property of the device over temperature, which is the electrical resistance of the device. The resistance will decrease as the thermistor heats up, resulting in an increase in current flow through the device. The change in its resistance also increases the more severe the temperature change. This phenomenon is known as the “B-Value” which is a measure of how steeply the resistance changes as temperature is increased. The B-Value for the thermistor is determined at different points across its temperature range and is calibrated within the specific device.

Conclusion

The B57352V5104F360 is a temperature sensor from the NTC family of thermistors. It is especially useful for applications that involve temperature measurements due to its rapid response time, accuracy, and reliability. The basic principle of operation of this thermistor is that as its temperature increases, its electrical resistance decreases, which increases the current flow through the device. Its Particular curve coefficient (B value) is built into the device, with B=3470 and To = 25°C. Its resistance value can easily be measured by using an ohm meter and the device\'s wide temperature range of -40°C to +125°C allows it to be used in a variety of applications.
