Through Hole Resistors

Through-hole resistors are an electrical/electronic component made up of resistive wire wound around a form or core. They typically have two terminals, one end of the wire is connected to a terminal and the other end is connected to the core. They are available as single unit, dual unit, and even multi-unit, depending on the application. The resistance of the resistor is determined by the length of the wire and the resistive material of the wire. Through-hole resistors have been used to regulate voltage, current, and power in electrical systems and electronic circuits since the invention of the transistor.

PWR220T-20-1303J Application Field and Working Principle

The PWR220T-20-1303J through-hole resistor is a fixed value resistor designed for power management applications. It is typically installed on the main board of the consumer electronics and other advanced microprocessor systems during production. The PWR220T-20-1303J is composed of wirewound resistive elements in a metal housing which uses a 2-terminal electrically isolated terminal block. The PWR220T-20-1303J is available in four different voltage ratings – 2.1, 2.2, 2.3, and 3.0 Volt safe operating voltage.

The working mechanism of the PWR220T-20-1303J through hole resistor, is based on Ohm’s law which states that the voltage across a resistor is equal to the current that flows through it multiplied by the resistance of the resistor. When the electricity flows from the positive side to the negative side of the resistor, there is a certain small drop in voltage due to the resistance of the wirewound resistor. This causes a reduction in the overall voltage, thus controlling the flow of current. As the resistance of the resistor increases, the voltage drop decreases.

The PWR220T-20-1303J can be used to control, regulate and limit current in various electronic circuits and by controlling the current, it can also effectively protect sensitive components from over-current conditions. It can also be used as a voltage regulator as it is designed to maintain the hit and hold voltage of the circuit which maintains the constant output voltage of the system.
