The WR06X152JGL Resistor by Walsin is a 0603 size, thick-film based resistor that has a resistance of 1.5kO, a power dissipation of 100mW, a tolerance of 5%, a temperature coefficient of 100ppm/°C, and a maximum rated voltage of 75V. The 0603 size refers to the physical dimensions of the resistor, allowing it to be used in constrained spaces and electronics applications, while the thick-film construction allows for the resistor to have a good temperature and thermal cycle stability. The 1.5kO resistance ensures that the amount of current passing through the resistor is kept within a suitable and acceptable range for the application. The 100mW power dissipation and 5% tolerance rate ensure that the resistor can handle the voltage, current, temperature, and humidity levels associated with the application. The temperature coefficient and 75V maximum rated voltage of the WR06X152JGL ensures that the resistor does not get damaged by higher temperatures or voltages, preserving its longevity.
