Through Hole Resistors are unique components used in electronics and electrical engineering in order to regulate the flow of current through a circuit. The purpose of the resistors is to initially limit the current to safe levels and also to improve the quality of the current and signal being transmitted. The most common type of resistors, and the type used in the HHV1WSJR-73-91K, are made of metal oxide materials and they are known as Metal Oxide Film Resistors (MOFR).

The HHV1WSJR-73-91K is a through hole resistor that is intended to be used in high-temperature applications. It is built with a metallized film of cermet material for stability and reliability, which is encased in a ceramic body. The other components of the resistor include stainless steel end caps, a ceramic insulator, and a nickel-plated copper terminations. The performance of the resistor includes a power rating of 5W, an operating temperature range of -65–155°C, and a TCR (Temperature Coefficient of Resistance) of 10ppm/°C. This type of resistor is recommended for use in electronic equipment such as power supplies, industry, and medical devices, as well as for controlling current in motor drives, industrial controls, and other high-temperature systems.

The working principle of the HHV1WSJR-73-91K is based on a combination of resistive and inductive features. The resistance of the resistor is essentially determined by the characteristics of the cermet material, which is a combination of metal and ceramic. While the stainless steel end caps, ceramic insulator, and nickel-plated terminations electrically isolate the resistor, they also provide additional dimensional stability. The combination of these components form a resistor that is both reliable and temperature-resistant.

When the current passes through the resistor, it is opposed by the resistance of the cermet material, which is based on the specific combination of materials used to create the resistor. The resistance of the cermet material will thus control the amount of current that passes through. The inductive features of the resistor then provide additional stability and protection against voltage spikes and other fluctuations.

Overall, the HHV1WSJR-73-91K is an ideal choice for a through hole resistor. It offers high temperature performance, stability, and reliability. The combination of its cermet material and other components make it an optimal solution for applications in which current levels and temperature need to be regulated in order to avoid damage and maintain the highest quality of signal and current.
