NHQM203B400T10 Temperature Sensors - NTC ThermistorsNTC thermistors are temperature sensing devices composed of semiconductor materials. They have a wide range of applications, from industrial to consumer electronics. The NHQM203B400T10 is a temperature sensor manufactured by Novasense, a company specializing in thermal sensing solutions. This small, cylindrical thermistor features a Nickel-Cadmium alloy inner electrode, giving it a wide operational range of -50°C to 150°C.The NHQM203B400T10 is intended for use in consumer electronic applications where reliability and accuracy are paramount. This thermistor’s low thermal inertia enables excellent performance in dynamic temperature changes, making it ideal for applications such as computers and mobile phones.How does an NTC thermistor work? NTC thermistors are characterized by their resistance, which decreases as temperature increases. This changing resistance is what makes the sensor a useful tool in temperature measurement. The NHQM203B400T10 utilizes an inner Nickel-Cadmium electrode which produces a consistent and stable resistance/temperature relationship over its operating range. The NHQM203B400T10 utilizes a two-wire hook up system, with one wire being connected to a constant voltage (5V) and the other being connected to ground. The thermistor’s variable resistance is then determined by measuring the voltage difference between the two points. By carefully analyzing the voltage input and output curves, the thermistor’s resistance can be determined at any given temperature.The NHQM203B400T10 is mostly used in applications where reliable and long lasting temperature readings are required. Common applications of the NHQM203B400T10 include automotive electronics, personal computers, lighting regulation, and home appliances. Automotive electronics applications benefit from the thermistor’s wide operating range of -50°C to 150°C; this range makes the NHQM203B400T10 ideal for applications involving hot and cold temperature range changes.The NHQM203B400T10 thermistor is also notable for its complexity of options; the thermistor is available in two size diameters (3.3mm and 4.2mm), multiple wiring options, and a range of sensitivities. The selection of a more sensitive thermistor allows for greater accuracy in temperature measurements, and this model can be ordered with sensitivities ranging from -2.5mV/°C to -2.8mV/°C. In conclusion, the NHQM203B400T10 thermistor is a popular choice for temperature monitoring in consumer electronic applications. The thermistor’s wide operating range, low thermal inertia, and range of available sensitivities and sizes make it an ideal choice for applications requiring accurate and reliable temperature measurements.
