Working Principles

The 41JR20 resistor is a through hole resistor that operates on the principle of a negative temperature coefficient (NTC) thermistor. NTC thermistors are semiconductors that decrease resistance as the temperature increases. As the temperature rises, the number of free electrons in the semiconductor decreases, the conductivity increases, and the resistance decreases.The resistance of the 41JR20 is measured in Ohms, and its temperature characteristics are expressed in terms of its Positive Temperature Coefficient (PTC). The PTC is the temperature coefficient of the negative temperature coefficient of the thermistor. The PTC for the 41JR20 is 0.00148. This means that as the temperature increases, the resistance will decrease exponentially by 0.00148 ohms/°C with the same magnitude.

Conclusion

The 41JR20 resistor is a through hole resistor that features excellent temperature stability, wide operating temperatures, and is suitable for a variety of general purpose applications. The 41JR20 operates on the principle of a negative temperature coefficient (NTC) thermistor, and its resistance is measured in Ohms and its temperature characteristics are expressed in terms of its Positive Temperature Coefficient (PTC). The 41JR20 is an ideal choice for applications that require accuracy, reliability, and long-term stability.
