NTCS0402E3104HHT Temperature Sensors - NTC ThermistorsThe NTCS0402E3104HHT is a NTC (Negative Temperature Coefficient) thermistor from ROHM Semiconductor. It is a small size device with a chip size of 0402 (1.1×0.8mm). The NTCS0402E3104HHT was specifically designed for use in temperature measurement in the 0° to +60°C range.In thermistors, the resistance decreases when the temperature rises, which provides a useful way of measuring temperature. The NTCS0402E3104HHT is made of a sintered metal oxide with a highly sensitive resistance-temperature characteristic. A unique Ag element is used and diffusion bonding is applied to ensure a stable temperature-resistance characteristic and reliability.NTCS0402E3104HHT applications The NTCS0402E3104HHT is commonly used in various types of temperature sensing applications. It can be used as a temperature sensor in HVAC systems, temperature control systems, electronic skin, transportation systems, and other IoT applications.Additionally, the NTCS0402E3104HHT is also suitable for a variety of temperature measurement applications such as: • Home appliances • Automotive • Industrial equipment • Medical systems • Wireless charging systems • Data centers • Lighting systems NTCS0402E3104HHT Working PrincipleThe resistance of the NTCS0402E3104HHT thermistor decreases as the temperature increases. The resistance-temperature curve of the thermistor is highly nonlinear, so it requires a high-accuracy reference voltage and amplifier circuit to measure its resistance-temperature characteristics accurately.The NTCS0402E3104HHT has two pins, a positive (Pin 1) and a negative (Pin 2). If a voltage is applied across them, the voltage developed across resistor will vary with the temperature; and the voltage keeps on increasing as the temperature rises. The voltage developed is proportional to the temperature which can then be used to calculate the temperature.ConclusionThe NTCS0402E3104HHT is well-suited for accurate temperature measurement in applications requiring a small size. The resistance-temperature characteristic of the device ensures a highly linear and accurate measurement over the entire temperature range from 0° to +60°C, which makes it an ideal choice for various temperature sensing applications.
