Additional Details

The NCP15WF473F03RC is an NTC thermistor, meaning its resistance decreases as temperature increases. The R25 value of 47 kΩ indicates the resistance at 25°C, which is a key parameter for selecting the appropriate thermistor. The B-constant (B25/85) of 4600 K describes the relationship between resistance and temperature, enabling precise temperature calculations. The key difference between this part and similar parts is the ±1% tolerance, which offers higher accuracy compared to the ±5% tolerance found in other models. The 0603 case size is small and ideal for surface mount technology (SMT). The thermistor is RoHS compliant. The NCP15WF473F03RC is frequently used to protect circuits from overheating by reducing current flow as the temperature rises. This component is commonly implemented in battery chargers and other consumer electronic devices to ensure safe and reliable operation. Its robust construction guarantees consistent performance over extended periods. The NTC thermistor is designed for easy integration into electronic circuits, providing a reliable and precise method for temperature sensing and compensation. The tolerance is a significant feature because it allows for more precise and reliable temperature readings and control.
