Through hole resistors are a common type of resistor that is constructed by installing a cylindrical body that has a metal core where resistor elements are attached. The resistor elements form a spiral pattern inside the resistor body and are usually made out of ceramic, carbon, or metal materials. The metal core holds the adjacent resistor elements and helps to ensure electrical contact with the resistor elements.

The HHV-25FT-52-732K through hole resistor is a wirewound resistor with an axial lead attached to the resistor body, which is sealed in an A_case epoxy coating. This type of resistor is designed to provide precise resistance values at high power dissipation levels, up to 225 Watts. It is often used when precision and higher power levels are required and is frequently used in the defense, medical, aerospace, power, automation, and telecommunications industries.

The primary application fields of the HHV-25FT-52-732K through hole resistor include battery chargers, voltage and current measurement, power supplies, motor drives, RF applications, high power switching, and high wattage audio systems. The HHV-25FT-52-732K resistor can also be used in applications where safety, reliability, low DC resistance, and other extreme environmental conditions are required.

The working principle of the HHV-25FT-52-732K through hole resistor is the same as with other through hole resistors. Current passes through the resistor body and is dissipated as heat in the resistor elements, resulting in a linear proportionate drop in voltage. The resistor’s element materials and heat-dissipation characteristics determine its resistance value and maximum wattage rating. As the current passes through the resistor, its temperature increases, and this increase in temperature diminishes the resistor’s resistance value, making it difficult to maintain a constant resistance.

The HHV-25FT-52-732K resistor is rated for 225 Watts of power dissipation and provides precise resistance values. The resistor’s body is designed to dissipate heat quickly, making it suitable for applications where high power dissipation is required. The resistor is also sealed in an A_case epoxy coating to protect it from environmental conditions. The axial lead attached to the resistor body also ensures contact with the resistor element.

In conclusion, the HHV-25FT-52-732K through hole resistor is a popular type of through hole resistor that is designed for high power dissipation and excellent resistance value accuracy. It is often used in industrial applications such as battery chargers, voltage and current measurement, and power supplies, as well as in other extreme environmental conditions. The resistor works by allowing current to flow through the resistor body and is dissipated as heat in the resistor elements, resulting in a linear proportionate drop in voltage. The resistor body is designed to dissipate heat quickly, allowing it to maintain its precise resistance values and wattage rating.
