Through hole resistors are among the most common components used in electronic circuits. As their name suggests, through hole resistors are resistors that are mounted through a hole or via on a printed circuit board (PCB).

The H8274RDZA is an example of a through hole resistor. This resistor is a wire-ended component with an axial lead spacing of 2.54 mm (0.1 inch). It consists of a wire-wound cylindrical resistor element, which is coated with a non-conductive protective material. The body of the resistor is stamped with manufacturer\'s markings such as a code number, the resistance value, and the tolerance.

The H8274RDZA is designed for use in high voltage and high power applications. It is rated for a maximum power dissipation of up to 200 watts. Its operating temperature range is -55°C to +150°C. The H8274RDZA has a resistance range of 0.1 ohms to 10 megohms, with a tolerance of up to +/- 5%.

The working principle of the H8274RDZA is relatively simple. As current flows through the resistor, some of the electrical energy is converted to heat. This conversion is based on Ohm\'s law, which states that the current through a resistor is proportional to the voltage across it. In other words, the higher the voltage, the greater the current. The heat generated by the resistor is dissipated into the surrounding environment, therefore limiting the current flowing through the resistor.

The H8274RDZA is ideal for applications requiring high voltage and/or high power handling capability. It is commonly used in motor drives, power supplies, switching power supplies, and other high voltage and high power circuits.

Due to its high reliability and low impedance, the H8274RDZA is also well suited for use as a surge arrestor. It is designed to protect sensitive electronics from surges of voltage by providing a low-impedance path to ground. It can also be used as a power limiting resistor in conjunction with a circuit breaker or fuse.

Overall, the H8274RDZA is an extremely versatile through hole resistor. Its high power rating, wide resistance range, and low impedance make it ideal for use in a variety of medium and high power applications.
