Temperature Sensors - NTC Thermistors cover a wide array of devices that measure temperature. One such device is the TBPS0R154K455H5Q, which is a negative temperature coefficient (NTC) thermistor. This article will discuss the application fields and working principle of this device.

Application Field

The TBPS0R154K455H5Q is a high-sensitivity thermistor and is commonly used for applications demanding reliable and highly accurate temperature measurement. It has a wide measurement range, from -30°C to 260°C, allowing it to be used in a variety of applications. Some typical application fields using this device include:

• High accuracy measurements in industrial systems and automotive applications
• Temperature control systems in medical equipment, process control systems and medical equipment
• Heat-sensitive systems such as refrigeration systems, air conditioners, and heating systems

Working Principle

NTC thermistors work on the principle of temperature dependence of electrical resistance. When a current passes through an NTC thermistor, its resistance decreases with increasing temperature. This relationship between resistance and temperature is captured in the B-Value, which is the temperature coefficient of resistance of the device.

The TBPS0R154K455H5Q has a B value of 3 447K, meaning its resistance decreases by 3*10^-3 ohm per °C increase in temperature. This makes it particularly well suited for high accuracy applications as it enables the device to measure small changes in temperature. The device also has relatively low self-heating compared to other NTC thermistors, making it more suitable for situations where accuracy is critical.

In terms of its physical design, the TBPS0R154K455H5Q has an epoxy-coated body which ensures greater thermal stability and accuracy. The device is insensitive to electric fields and operating frequencies, allowing it to be used in a wide range of applications. It is also designed to have low moisture absorption, making it resistant to humidity changes.

Overall, the TBPS0R154K455H5Q is a highly accurate and reliable thermistor with a wide range of applications. Its excellent B value, low self-heating and epoxy coating make it particularly well suited for applications where accuracy is paramount.
