The OK9145E-R52 through hole resistor works by reducing the effective current passing through the resistor element. This resistance is determined by the electrical characteristics of the material used in the resistor construction. This resistance causes the voltage dropped across the resistor element to be lower than the supply voltage, thereby limiting the current flowing through the circuit. The resistor also operates by dissipating the power generated from the current passing through it. The dissipated power is converted to heat, which is then dissipated to the environment through conduction or convection.
