NTC ThermistorsNTCALUG03A473H is a type of temperature sensor that belongs to NTC thermistors family. NTC stands for Negative Temperature Coefficient, which means that the temperature coefficient of NTC thermistors is negative. This family of thermistors are also widely known as PTC – Positive Temperature Coefficient thermistors. NTC thermistors are semiconductor devices, composed of sintered metallic oxides, and are notoriously known for their high precision and accuracy when measuring temperature, letting it stand out from other temperature sensors like thermocouples and RTD (Resistance Temperature Detectors).ApplicationsNTCALUG03A473H temperature sensors are among the most popular types of NTC thermistors. It is widely used in many applications where high precision and accuracy of temperature measurements is required, such as in medical equipment, industrial automation control, automotive electronics and smart home technologies. For instance, NTCALUG03A473H sensors have been adopted by exhaust gas recirculation (EGR) systems in many automotive control systems, for reliable and accurate temperature analysis.Work PrincipleNTCALUG03A473H temperature sensors rely on a physical phenomenon known as temperature coefficient. It`s a resistance that introduces a voltage drop to the circuit when the temperature changes. As the temperature rises, the resistance within the sensor decreases. Conversely, as the temperature drops the resistance rises. This resistance variation will be converted into a voltage signal, so it can be read by a compatible electronic system.Types of NTCALUG03A473HThere are three major types of NTCALUG03A473H sensors: Radial (threaded cylindrical shape), Clip-On (clips-on to the substrate) and Lug (wire lead shaped). The most popular type is the threaded cylinder type, featuring small size and often used in demanding applications such as automotive control systems, medical devices and industrial automation. Clip-on and Lug type sensors are more popular in automotive applications.CharacteristicsNTCALUG03A473H temperature sensors feature an excellent temperature resilience, ranging from -30 to 130 Celsius degrees, with a tolerance of up to 1%, and a response time of around 30 seconds. Their resistance range can reach up to 50KOhm at 25°C, and their voltage drop is typically around one volt in the presence of a 5V drive.AdvantagesThe biggest advantage of NTCALUG03A473H temperature sensors is their high accuracy and precision of measurement. Their materials also ensure a long lifespan which makes them perfect for demanding applications such as automotive control systems, medical devices and industrial automation. Additionally, their small size and robust nature make them ideal for tight spaces, and their low-voltage drive make them suitable to be integrated with microcontrollers.ConclusionNTCALUG03A473H is a type of NTC thermistor, composed of sintered metallic oxides and featuring a high precision and accuracy when measuring temperature. NTCALUG03A473H temperature sensors are typically used in automotive control systems, medical devices and industrial automation due to their high accuracy and precision, small size and long lifespan. The three main types are the Radial (threaded cylindrical shape), Clip-On (clips-on to the substrate) and Lug (wire lead shaped) models. Their resistance range can reach up to 50KOhm at 25°C, and their voltage drop is typically around one volt in the presence of a 5V drive.
