Through Hole Resistors, commonly known as axial resistors, are electronic components used to reduce electric current and provide a known voltage. This type of resistor is fixed by being soldered into holes on printed circuit board (PCB) and draws its electrical power from the application field. The 40J3R0E Through Hole Resistor is an axial leaded resistor which provides a reliable solution for heat management through its distinct design.

The 40J3R0E Through Hole Resistor, also commonly known as a 40 ohm 3W 5% Through Hole Resistor, is composed of five different components: a wire lead, a resistor body, a resistor coat, an insulating resistant coating and an insulating container. The resistor is composed of a contact that connects to ground, two insulated leads spaced apart by a resistor body, and housed in an insulating container. The resistor body contains a layer of ceramic or insulating material that prevents electrical contact between components and provides protection from heat, vibration and moisture. Between the two leads is a resistor coat, which provides the amount of resistance needed for the current in the application field. Finally, the outer layer of coating is a materials such as epoxy that insulates the resistor and prevents electrical contact with other components on the PCB.

The 40J3R0E Through Hole Resistor is designed to maintain heat and electrical resistance while still providing efficient conduction of the application’s required current. Its two insulated leads provide reliable conduction and the resistor body acts as both an insulator and a heater, allowing it to dissipate heat more efficiently. The coating provides a layer of insulation to prevent electrical contact with other components on the PCB and the outer container insulates the entire unit.

The 40J3R0E Through Hole Resistor works by allowing a certain amount of electrical current to pass through it, for a defined voltage and power rating. When the current passes through the resistor, it generates heat which then passes through the resistor body. The resistor body works to dissipate this heat more efficiently than if it were being generated through the application field. The resistor then absorbs the heat and is held in this state until the voltage drops. The resistor then releases the heat into the application field and reduces the overall current that passes through it, ensuring that the appropriate level of energy is maintained.

The 40J3R0E Through Hole Resistor is a reliable and efficient component used in many different applications. It is commonly used in applications such as power supplies, accelerators, motors, amplifiers, and digital circuits. In these applications, the resistor works to limit the amount of current passing through the application and maintains the desired level of energy. This ensures that the application works at an optimal level and that it is safe from electrical and thermal damage. The 40J3R0E Through Hole Resistor is the perfect component for situations where reliability and efficiency are needed in high-profile applications.
