Through hole resistors are used in a variety of applications. The RWR80S1180FRB12 is designed to provide a very stable resistive element in high voltage circuits. This resistor features a low rated power of only 0.4 watts and an excellent heat sinking system.

The design of the RWR80S1180FRB12 makes it suitable for a wide variety of applications, from instrumentation, precision amplifiers, and line voltage regulators to motor controls, grounding networks, and voltage dividers. In addition, the resistor can be used as a current sensing element in line current inrush or surge suppression applications.

The RWR80S1180FRB12 consists of a ceramic substrate that has a thin-film active layer of polycrystalline tantalum nitride deposited on it. This layer is typically around 0.2 microns thick and it is patterned by photolithography to create the required resistance values. The resistor is then encapsulated in an epoxy coating and then passivated for protection against environmental conditions.

The working principle of the RWR80S1180FRB12 is based on the behaviors of the electrons as they move through the resistor’s active layer. When a voltage is applied across the resistor, the electrons within the active layer are accelerated by the electric field and interact with the crystal lattice of the substrate, creating resistance. This resistance builds up until the voltage across the resistor is equal to the applied voltage, resulting in a current flow.

The exact value of the resistance produced by the RWR80S1180FRB12 is determined by its geometry and the material used in its active layer. The unique design of this resistor allows it to maintain a consistent resistance value over varying temperature ranges, ensuring precise performance in high-voltage circuit applications. In addition, the resistor has an excellent self-healing property, enabling it to recover from any transient surge conditions.

In summary, the RWR80S1180FRB12 through hole resistor is a stable, reliable, and accurate resistive element for use in a variety of high-voltage circuits. Its unique design helps ensure precise performance and stability in a wide range of applications, while its self-healing property helps protect against surge conditions.
