Through Hole Resistors

Through hole resistors provide electrical resistance in a variety of applications. The H8274RDYA is one type of through hole resistor, possessing a relatively low temperature coefficient of resistance. This type of resistor is commonly used in power supplies, circuit protection, overload protection, and power amplifiers.

The H8274RDYA is a through hole resistor with a 5 watt power dissipation rating and an absolute tolerance of +-5%. With a radial lead construction and an epoxy molded body, this type of resistor has a broad spectral response at a variety of frequencies. It is also designed to withstand the equivalent permanent temperature and humidity of 85/85. This makes it ideal for use in environments where moisture and temperature fluctuation may occur.

The H8274RDYA is composed of two main parts: a ceramic body and a metalized electrode. These two components are electrically connected by a coil of gold or silver plated wire. This metalized electrode acts as a heat sink, absorbing heat from the ceramic body and transferring it to the surrounding air. This provides the resistor with an improved temperature coefficient of resistance.

Electrical resistance is created when electrons flow across the resistor, from the metalized electrode to the ceramic body. The number of electrons that flow is determined by the applied voltage, current, and resistance. In addition to creating resistance, the resistor also helps reduce noise by providing a stable impedance that absorbs unwanted electrical signals.

The H8274RDYA through hole resistor is used in a wide variety of applications, including power supplies, instrumentation, amplifiers, and motor controls. As a 5 watt resistor, it is capable of handling higher current than other types of resistors. This makes it ideal for applications involving greater amounts of power.

The overall performance of the H8274RDYA is dependant on the specific application. For example, in power supplies, it is not uncommon for the resistor to be used in a series connection with other components, such as capacitors and transistors. When used in this manner, the resistor helps ensure that the output of the power supply remains stable, regardless of changes in input power or load.

The H8274RDYA is an ideal resistor for applications that require excellent temperature stability. It is able to withstand considerable power at high temperatures, and provides excellent protection against overloads. Its low temperature coefficient of resistance and robust construction make it an ideal choice for most applications.
