Through Hole Resistors play a very important role in many electronic devices, providing precision voltage and current regulation. The HHV-25FR-52-187K is an example of such a resistor, and is available in both axial and radial packages. It is a non-inductive, ceramic-sealed, surface-mount resistor with a temperature coefficient of 0-750 ppm/K and a operating temperature range of -55 to +125 °C. Its resistance range is 0.1 to 10 K W.

This resistor is designed to handle up to 1.25 W of power. The resistor\'s construction is made of a coiled metal element surrounded by a ceramic sleeve and coated in a resin which helps dissipate heat from the device. This provides excellent thermal stability and ensures that the resistor can handle the full wattage at all temperatures.

The resistor\'s electrical properties are very stable and precise - it has a tolerance of 0.5% and minimum voltage derating. This makes it a great choice for precision circuits, such as those used in microcontrollers, system-on-chips, and other high-performance applications.

The primary application field of the HHV-25FR-52-187K is in precision voltage regulation. It can be used in applications where a precise amount of voltage needs to be maintained, such as in power supplies, battery-charging circuits, and various motor control systems. It can also be used in temperature-controlled systems where precise amounts of current need to be regulated.

The working principle of a through-hole resistor is relatively simple. When a voltage is applied across it, the resistor acts like a choke, preventing the flow of current through it. This is because the resistance offered by the resistor limits the amount of current that can pass through it. The more resistance the resistor offers, the less current can pass through it.

The resistor\'s resistance is determined by the resistive material used in its construction. Different materials have different resistance, so by selecting the right material, it is possible to obtain a resistor with the desired resistance. The HHV-25FR-52-187K, for example, is made of a combination of different materials that allows it to have a resistance range of 0.1 to 10 KΩ.

In addition, the resistor\'s thermal properties and low voltage derating make it suitable for applications where temperature control and precise voltage regulation are paramount. For these reasons, the HHV-25FR-52-187K is a popular choice of through-hole resistor for many electronic devices.
