Through Hole Resistors

The WW12FT143R is an example of a through-hole resistor, and belongs to a class of components known as passive components. A resistor is an electronic component that restricts the flow of current. Resistance is measured in ohms and is usually symbolized by the Greek letter omega (Ω).

Application Field

WW12FT143Rs are used in the right applications, they perform their electrical function well, and are often the part of choice for circuit designers. Through-hole resistors come in a variety of shapes and sizes, and are typically used in circuits that require precision, durability, or the ability to handle large values of power. Some specific applications include radio frequency (RF) circuits, where their size and weight make them ideal for use in small space, and in analog applications where their precision and stability make them the perfect choice.

Working Principle

The working principle of this type of resistor is fairly simple to understand. A through-hole resistor contains an electrical current-limiting element which is usually made from manganin, an alloy of nickel, silver and zinc. This element, in combination with other materials that make up the resistor, creates an electrical path that limits the current. The amount of current restriction created by the resistor is determined by its resistance value, which is specified by its manufacturer.

The WW12FT143R is a specific type of through-hole resistor which is commonly used in analog circuits due to its stability and precision, as well as its ability to handle large amounts of power. This type of resistor can be placed in one of two ways, depending on the amount of current that needs to be limited. It can either be placed directly on the circuit board for smaller amounts of current, or it can be inserted into a heat sink to dissipate large amounts of current without causing any damage to the circuit.

While through-hole resistors are relatively simple in design and function, they can play an important role in the correct build of a circuit. Not only do they create a precise and consistent current limiting path, but they can also be relatively resilient to high operating temperatures and magnetic interference. As such, they are a highly recommended component for all analog and RF circuits.
