Through Hole Resistors

Through hole resistors (THRs) are an essential part of many circuit designs. A through-hole resistor (THR) is an electronic component that limits or regulates the flow of electrical current in an electronic circuit. The THR is composed of a uniform resistor element that is placed inside a ceramic or phenolic housing. The housing is often ceramic and includes two or more terminals, with the one lead connected to the current path, and the other terminal connected to ground.The common RWR78S1332FPB12 THR is a fixed-value resistor that has been designed to fulfill a wide range of basic needs in various circuit design applications. It is a 12 watt through hole resistor rated at 2 Watts per square inch. The tolerance rating for the resistor is ±5%. The body size of the resistor is 0.400 square inch which is also the maximum power rating of the component. The THR has an extensive resistance range from 5Ω to 33KΩ.The resistor has a metallic black body and its power dissipation is 12 Watts. This component has two pins which have molded mounting flange. Its durable construction and low-stress design has made it suitable for many different applications.The application field for the THR model RWR78S1332FPB12 is mainly related to controlling basic circuit noise. These components are also used for impedance matching, control current flow and voltage regulation. They may also be used as isolation resistors, bleeder resistors or motor speed regulators. This THR can also be used as a voltage dividers to obtain different voltages.The working principle is based on the basic electrical principles. It reduces the current travelling through the resistor by allowing electrons to flow through the resistance material. The heat generated by the electron\'s flow is dissipated by the resistor\'s heat sink. The voltage and the resistance of the THR are related, so by varying the voltage, the amount of current passing through the resistor can be changed.In general, THR’s can be used in low-power applications, but can also be used in high-power applications. Since the THR has a high degree of accuracy and stability, it is ideal for use in power regulation. As well, many electronic systems employ THRs to provide interference reduction. Furthermore, some THR’s are designed to be redundant in the event that the primary THR fails.The RWR78S1332FPB12 THR is an ideal component for use in low-power circuitry, and works well for applications where fine-tuning of voltage and current levels is critical. It is composed of a ceramic housing and two terminals for connection, and dissipates heat through the casing. Its resistance range is wide, from a minimum of 5Ω to a maximum of 33KΩ, and is designed to handle 12 Watts of power.
