NTC thermistors, short for Negative Temperature Coefficient Thermistors, are temperature sensors that detect and measure temperature changes. The NTCS0805E3333GHT is one of the most widely used NTC thermistors due to its small size, high accuracy, and fast response time. This article will discuss the application field and working principle of the NTCS0805E3333GHT.The NTCS0805E3333GHT is a surface-mountable NTC thermistor that is typically used for high precision temperature sensing applications. It is ideal for applications that require the highest sensitivity due to its superior signal-to-noise ratio. The thermistor has an operating temperature range of -40°C to 85°C, which makes it suitable for a wide range of applications including industrial, automotive, medical, and consumer electronics.The NTCS0805E3333GHT is an octagonal shape with a thick film element that provides superior temperature sensing accuracy and a fast response time. The element is coated with a dielectric layer that is designed to provide high insulation resistance and low parasitic capacitance. The thermistor also features a specially designed metal oxide thin film (MOSFET) that acts as a protective barrier to prevent electrochemical corrosion.The working principle of the NTCS0805E3333GHT thermistor is based on the principle of thermal energy transfer. When the temperature of the environment is greater than the thermistor’s operating temperature, heat is transferred from the environment to the thermistor. This heat transfer causes the metal oxide thin film to become more conductive, resulting in an increase in resistance. Conversely, when the temperature of the environment is lower than the thermistor’s operating temperature, heat is transferred from the thermistor to the environment. This heat transfer causes the metal oxide thin film to become less conductive, resulting in a decrease in resistance.By measuring the resistance of the NTCS0805E3333GHT thermistor, the temperature of the environment can be accurately determined. This is accomplished by using a voltage divider circuit wherein one side of the divider is connected to the thermistor and the other side is connected to a reference voltage. The output voltage of this circuit indicates the temperature of the environment.In summary, the NTCS0805E3333GHT is a surface-mountable NTC thermistor that is used for high precision temperature sensing applications. The thermistor features a thick film element that is coated with a dielectric layer, which provides high insulation resistance and low parasitic capacitance. The thermistor also has a metal oxide thin film that acts as a protective barrier. The working principle of the thermistor is based on the principle of thermal energy transfer. By measuring the resistance of the thermistor, the temperature of the environment can be accurately determined.
