Through Hole Resistors are electrical components that come in various shapes, sizes, and functions. Amongst these is the H8866RFCA resistor. The H8866RFCA, like many resistors, is a passive two-terminal electrical component that can resist the flow of electric current and dissipate energy of that same current. This particular type is a radial through-hole resistor and is composed of a metal film in a compact metal package. Rated at 4 watts, the H8866RFCA can handle high loads and highripple currents at up to 25 VDC or 16 VAC. This is due to the resistor having a very low thermal and electrical impediments when mounted properly.

A through-hole (TH) resistor consists of a resistor body and two soldered leads that run through a printed circuit board (PCB). The resistor body is typically made from carbon, ceramic, or metal film and is sealed by a ceramic undercoat, a metal cap, and wire-wound leads. It is designed to provide the necessary design stability by minimizing changes in resistance value due to thermal expansion or mechanical stresses resulting from mechanical loading of the component. The tolerances of the resistor, usually specified as a range from minimum to maximum voltage rating, determine the level of voltage or current this type of resistor is capable of handling.

The working principle of the H8866RFCA is simple. An electrical current passes through the resistor, resistors resist the flow of current and then dissipate that energy as heat. This dissipation of energy makes them useful for limiting the amount of current that can flow through a circuit. For example, a 4 Watt resistor can be used to limit the amount of current to a circuit’s specified level. Similarly, a 4 Watt resistor can also be used to reduce voltages.

The H8866RFCA also has some notable features and benefits. This component has a low temperature coefficient and good stability over time. It also has a very low thermal turn on voltage which results in minimal heat losses even at high current loads. Additionally, its long life is due to its high humidity imbibing properties. The H8866RFCA also contains a patented self-healing element, which, when combined with a clever stress relief tab, ensures reliable performance.

Overall, the H8866RFCA is a reliable radial through-hole resistor that offers a low thermal turn on voltage, high humidity imbibing properties, and a patented self-healing element. Its unique package design allows it to handle high loads and highly ripple currents at voltages of up to 25 VDC or 16 VAC. As a result, the H8866RFCA can be used for many applications, such as power supplies, motor drives, AC/DC converters, and more.
