Through Hole Resistors are one of the simplest bread-and-butter components in an electronics application. They are used to limit current unknown, providing a stable load in power supplies, and are essential when building a circuit. One of the most commonly used Through Hole Resistors is the H8147RDZA.

The H8147RDZA Through Hole Resistor is a common cylindrical resistor that is made of resistance wire wrapped around the core and enclosed in an insulating material. The core may also be comprised of ceramic, mica, or any other material with a low thermal coefficient of resistance. The resistor is enclosed in a sealed metal housing to prevent any changes in resistance due to temperature and to prevent moisture from entering and increasing the resistance.

The H8147RDZA resistance range is from 0.3 OHM to 10.2 K OHM, and it can handle up to 200 Watts of power. The resistance value of the H8147RDZA is marked with a dimple on the top of the metal housing, followed by the resistance value in ohms, followed by the rated power.

The H8147RDZA typically come in a TO-220 package but can also be found in other packages such as an A-Shell, Radial, and Discrete. The TO-220 package is ideal for applications where power dissipation is in the range of 10-50 watts and the resistor must be installed in a restricted space.

The H8147RDZA Through Hole Resistor operates according to Ohm’s law which states that the current passing through a resistor is inversely proportional to the resistance. For example, if the resistance is doubled, the current will be halved. This is why the H8147RDZA is so useful for limiting current in a circuit.

The H8147RDZA is used in a variety of applications such as circuit protection, motor control, adjustable voltage regulators, and limit current in high power systems. For example, in power supplies, the H8147RDZA can be used in conjunction with a power cycling circuit to limit the maximum current, which in turn keeps the heat generated within acceptable levels. It can also be used to regulate voltage in adjustable voltage regulators.

The H8147RDZA Through Hole Resistor also offers excellent temperature stability in a wide temperature range, up to +200°C. This makes it well suited for many applications in demanding environments.

In conclusion, the H8147RDZA Through Hole Resistor is a versatile and reliable component that can be used in many applications. Its ability to handle high power levels, excellent temperature stability, and wide resistance range make it an excellent choice for many circuit designs.
