Temperature sensors are important components in the majority of home and industrial automation systems. They allow detectors to precisely monitor the condition of the system and initiate corrective action if needed. NTC thermistors are one of the most common and reliable thermistor components available for use in thermal sensing applications. The NHQ203B400T10 is a popular NTC thermistor which is used in many temperature sensing applications.

Overview

The NHQ203B400T 10 is an insulated, bead-type NTC thermistor. It is composed of a two–core beads that are connected and formed in a particular way. The thermistor has a PTC coefficient of temperature (-6.6%/K) and is composed of a manganese dioxide-based negative temperature coefficient (NTC) material. It has a resistance of 400 ohms (at 25°C) and has a maximum temperature of 280°C. It has an operating temperature range of -40°C to 120°C, a maximum voltage of 20V, and a Power Dissipation of 150mW.

Applications

The NHQ203B400T10 is commonly used in temperature sensing applications, due to its reliable performance and its accuracy. In particular, this thermistor is often used in automotive and aerospace applications to monitor environmental temperatures inside the cabin or engine bay. It can be used in HVAC systems to monitor temperatures in office buildings and homes. Additionally, it can be used in industrial processes to monitor temperature of equipment and personnel. The NHQ203B400T10 is also suited for many other temperature sensing applications as it is a low-cost and reliable solution.

Working Principle

The NHQ203B400T10 relies on the principle of resistance as a parameter for temperature measurement. It follows the negative temperature coefficient (NTC) of semiconductor materials, which means that its resistance decreases with increasing temperatures. It has two cores, one connected to a voltage source and the other to a load. When heat is applied to the thermistor, its resistance decreases, by a set amount, based on its PTC coefficient of temperature. This change in resistance is detected by a voltage or current meter, and the temperature is determined based on the amount of change in resistance.

The NHQ203B400T10 thermistor is a reliable and accurate temperature sensor that is widely used in temperature sensing applications. It can handle temperatures ranging from -40°C to 120°C, and can withstand a maximum voltage of 20V. It follows the NTC principle and has a PTC coefficient of temperature of -6.6%/K. With its low cost and reliable performance, the NHQ203B400T is an ideal solution for use in automotive, aerospace, HVAC, industrial, and other temperature sensing applications.
