Through Hole Resistors are components that effectively set a limit on the flow of electricity in a circuit. By limiting the current, an application can be made to run more efficiently and safely. The resistance of the component is determined by the material it is made from, as well as its physical size and shape. The H4487KBCA is a Through Hole Resistor used for a variety of applications, and it is important to understand its function and how it works.

The H4487KBCA is a cylindrical, axial leaded resistor made from metal oxide film material. It is designed to provide resistance for many applications, including power supplies, switching supplies, amplifiers, audio equipment, and instrumentation. The resistance can be set manually or automatically by adjusting the length of an integral metal tube, referred to as a resistance element. The end caps on the element contain a locking mechanism, so that the position remains secure during operation.

The H4487KBCA can be used for a variety of applications, including voltage divider networks, current limiters, bias circuits, peak clamping, and power rating protection. It is often used to set the precise resistance in order to properly regulate the flow of current in a circuit. The device offers high accuracy over a range of operating temperatures, up to 150 degrees Celsius, and it is able to withstand both high and low currents without significant loss of resistance value.

The working principle of the H4487KBCA is simple. When current is applied to the resistor, the resistance element generates heat, which in turn causes the resistance to increase. The end caps act as a self-adjusting system and turn the resistance element, thus increasing or decreasing the resistance, as required. This ensures that the resistor is able to maintain a consistent resistance value despite changes in temperature, current, or voltage.

The H4487KBCA is an ideal choice for many applications because of its combination of accuracy and durability. It also has a very low profile, allowing it to be used in space-constrained applications, as well as systems that require higher power ratings. As an efficient heat-dissipating component, the H4487KBCA is able to maintain a consistent resistance value over time, ensuring reliable performance for any application it is used in.
