A through hole resistor is an electrical component that functions as a resistor, but with a specific design to enable it to be easily installed into a circuit board. The H8365RBYA is a through hole resistor from Vishay Intertechnology and is part of its series of Power Metal Strip Through Hole Resistors. It is designed to act as a power supply line for voltage-sensitive devices like op-amps or FETs, as it features a higher current rating than any other resistor from the Vishay Metal Strip resistor range.The H8365RBYA is available in surface-mounted and axial-leaded packages, providing tremendous flexibility for applications requiring higher power dissipation, such as supplying power to voltage-sensitive circuitry or in applications that require a resistor that is physically larger than a chip resistor. The axial-leaded package is much larger and able to withstand higher power dissipation than the surface-mounted version. This increased power dissipation is enabled by the metal construction of the resistor\'s casing, which increases the air-flow over the resistor components.The resistor itself is constructed of a nickel-chromium alloy, which can handle high temperatures up to 250 degrees Celsius, as well as a low temperature coefficient of temperature (TCT) which ensures the resistor maintains a reliable resistance value over its entire operating temperature range. Additionally, the resistor\'s casing is made of a aluminum-magnesium alloy, which serves two purposes. Firstly, it provides a thermal barrier for the resistor components, preventing heat buildup, and secondly, it increases the thermal loading capacity of the resistor itself, allowing it to tolerate a higher power dissipation than conventional chip resistors.The resistor has a total power dissipation of 1.2 Watts, which is suitable for many applications. Its resistance range is from 0.1 Ohms to 350K Ohms, and its thermal time constant is a low 20 seconds, allowing for fast measurement of inductive elements. The maximum operating voltage is at 500 Volts DC, and the maximum pulse voltage is at 650 Volts DC.The key to the H8365RBYA’s power handling ability is its low TCt (4 minutes), which minimizes the risk of thermal damage to the resistor. It also features a low thermal impedance, which helps reduce voltage drop and maintain electrical system efficiency. The resistor\'s high operating temperature range allows it to be used in a wide range of applications, including automotive, power supplies, audio, and consumer electronics.In conclusion, the H8365RBYA is a robust, reliable through-hole resistor from Vishay Intertechnology. It is available in both surface-mounted and axial-leaded packages, and is suitable for a wide range of applications due to its temperature range and high power dissipation. With its low thermal time constant, low TCt and low thermal impedance, it can handle higher power dissipation and greater system efficiencies than other through-hole resistors. It is therefore, an ideal choice for designs requiring a power supply line for voltage-sensitive devices.
