Working Principle

The PSM500JB-22R through hole resistor consists of a metal alloy core that is surrounded by a ceramic outer layer. The metal alloy core acts as the resistance element and its resistance is determined by the number of layers of ceramic that surround the core. When a voltage is applied to the resistor, the electrons flow through the metal alloy core and the ceramic layers reduce the flow of electrons. This reduces the current, which in turn reduces the voltage. As the voltage is reduced, the power is dissipated as heat, which is then radiated away from the resistor.

The resistance of the PSM500JB-22R can be adjusted by changing the number of layers of ceramic surrounding the metal alloy core. By increasing the number of layers, the resistance can be increased, while decreasing the layers will result in a decrease in resistance. The resistance can also be adjusted by changing the thickness of the layers, which allows higher accuracy in the measurement of the resistance values.
