Temperature Sensors - PTC Thermistors

PTC thermistors are a unique type of temperature-sensitive resistor used for various electronic applications, such as thermal protection of electronic systems. The PTCCL09H101HBE is a semiconductor PTC (Positive Temperature Coefficient) thermistor that is optimally used for over-temperature protection of sensitive electronic systems. It offers a vast range of temperature protection up to 250°C, with a wide temperature range, low-cost, and high accuracy. In this article, we will discuss the application field and working principle of the PTCCL09H101HBE PTC thermistor.

Applications

The PTCCL09H101HBE can be used for a number of applications where accurate temperature control is needed. It can be used as a temperature sensor for home and office appliances, such as refrigerators, air conditioners, ovens, and microwaves. It can also be used for automotive applications, such as engine control systems, voltage converters, and intake and exhaust air temperatures. Additionally, it can be used in robotics, medical applications, industrial equipment, and other sensitive electronics.

Working Principle

The PTCCL09H101HBE consists of a small, thin-film, semiconductor PTC thermistor that has precisely balanced resistive and capacitive parameters. When the temperature rises above a predefined threshold, the resistance of the PTC increases exponentially, thus acting as an over-temperature protection device. The device provides a wide temperature range of temperatures from -55°C to 250°C, with a low thermal resistance of 0.7°C/W. It also offers a variety of temperature settings, including fixed, corner, linear, and maximums and minimums.Due to its small size, the PTC thermistor can be installed in any narrow space. It offers high accuracy, low cost, and a high degree of flexibility when selecting the appropriate temperature protection mode.

The PTC thermistor is constructed with a proprietary metal-oxide film, providing high temperature stability with a long working life. The resistance-temperature characteristics of the PTC thermistor are modeled mathematically by using a non-linear equation. This equation is used to determine the over-temperature protection threshold, and to control the rise and fall of the resistance. This ensures that the particular device operates reliably over its entire temperature range.

Conclusion

In conclusion, the PTCCL09H101HBE PTC thermistor offers a wide range of temperature protection with a low-cost, high-accuracy, small-size, and robust construction. Its proprietary metal-oxide film ensures superior temperature stability with a long working life. Moreover, the device\'s mathematical model can be used to set the over-temperature protection and accurately control the resistance of the device. Therefore, the PTCCL09H101HBE is ideal for all types of sensitive electronics that require accurate temperature control.
