Additional Details

The ERTJ1W104J has a specific resistance value at a reference temperature (typically 25°C). The resistance changes non-linearly with temperature. The temperature coefficient of resistance (TCR) specifies the amount of resistance change per degree Celsius. Thermistors are available in two main types: Negative Temperature Coefficient (NTC) and Positive Temperature Coefficient (PTC). NTC thermistors exhibit a decrease in resistance with increasing temperature, while PTC thermistors exhibit an increase in resistance with increasing temperature. It's crucial to consult the manufacturer's datasheet for precise resistance values, TCR, operating temperature range, and other relevant parameters. The datasheet will also provide information on the thermistor's self-heating characteristics and thermal time constant. Thermistors should be mounted in a way that minimizes thermal resistance between the thermistor and the object being measured.
