Working Principle of SQP25AJB-160R

SQP25AJB-160R is a through hole resistor. It has a round metal disc or cylinder with a thin film of metal-oxide bonded to the surface. The layer of resisting material enables the resistor to reduce the flow of electricity through the circuit. When properly calculated, the proper choice of the resistor will give enough resistance to limit the current flowing through each part of the circuit.

Essentially, the resistor works by dissipation of voltage energy. For any given resistor, there is a maximum wattage or dissipation power that it can handle, shown as the maximum wattage rating on the printed label. When the resistance is higher than the required value for the circuit, some of the energy from the circuit is dissipated as heat energy across the resistor.
