Temperature Sensors - NTC ThermistorsTemperature sensors are important components of electronic circuit designs in a variety of industries. One type of temperature sensor, an NTC thermistor, stands out as a key component in managing temperature control processes. The NTC thermistor operates on the principle of temperature-dependent electrical resistance, providing a viable and cost-effective solution to temperature management problems.The NHQM273B400T5 is an NTC thermistor manufactured by NTE Electronics. It uses a chip form factor, making it suitable for use in small microprocessor-based applications. The NHQM273B400T5 is rated for a nominal resistance of 400 ohms and is rated to a resistance tolerance of +/- 5% at 25 degrees Celsius. It has been designed for high-volume, cost-sensitive applications such as temperature sensing for automotive, medical, and industrial purposes.The NHQM273B400T5 operates on the principle of NTC thermistor. As its name implies, an NTC thermistor is a temperature-sensitive resistor whose resistance changes according to ambient temperature. This non-linear resistive characteristic will cause a corresponding voltage drop in the circuit when the thermistor is placed in series with another component. This effect is utilized for temperature sensing, as the voltage drop can be monitored and used as feedback to stabilize the temperature. The NHQM273B400T5 is specifically suited for applications where accurate temperature readings are required over a range of temperatures. It offers excellent long-term stability over a wide temperature range with minimal drift. The resistor has a temperature coefficient, also known as beta (β), of 3450K at 25°C. Furthermore, it has a temperature range of -25 to + 55°C and a dissipation constant of 2.5mW/K. These properties make the NHQM273B400T5 suitable for use in applications such as medical instruments, automotive electronics, and industrial controllers. The NHQM273B400T5 is a cost-effective solution for temperature sensing applications. It is a two-terminal device, meaning a simple voltage divider circuit is all that is required in order to measure the voltage across the thermistor. This design simplicity, combined with its low cost, makes it an attractive choice for temperature sensing systems.The NHQM273B400T5 has been tested to meet a number of international standards, providing reliability and safety for temperature monitoring applications. These standards include RoHS, UL, and CSA. The thermistor has also been extensively temperature-tested to ensure its performance over a wide range of temperatures and environmental conditions.All in all, the NHQM273B400T5 is an excellent choice for temperature-dependent applications, given its reliability, accuracy, and cost-effectiveness. The thermistor is a compact and versatile temperature regulator with excellent long-term stability and consistent performance, making it a reliable and dependable solution for a variety of temperature sensing applications.
