Through Hole Resistors are electrical components used to control current in circuits. NFR25H0006808JR500 is one of the Through Hole Resistors available on the market. This resistor is popularly used in RF amplifiers, video amplifiers, audio amplifiers, voltage regulator circuits, and filter circuits. It is designed to handle currents up to 25A, making it suitable for many applications.

The NFR25H0006808JR500 is formed as an axial lead resistor, which means that it is constructed within an axial lead resistor body. It includes a metal resistor case, a ceramic resistor element, an insulating resistor sleeve, and a resistive lead wire. The metal resistor case is made from nickel plated steel and has a ceramic resistor element covered by an insulated sleeve. The lead wire is soldered onto the resistive layer and has a length of 8 inches. The resistive material in the lead wires is made out of a nonvolatile resistive cement.

The working principle behind the NFR25H0006808JR500 is simple. As the current runs through the resistor, it passes over a resistive material within the lead wires, and the resultant electrical resistance is then imposed on the current. This resistance produces a voltage drop depending on the current, thus providing control of the current in the circuit.

In comparison to a chip resistor, a through hole resistor provides increased thermal stability. This is due to the larger size of the resistor and the more robust resistive material used in its construction. As a result, it can handle higher currents for extended periods without producing heat buildup. This means that the resistor will last longer and will be available for use longer.

The NFR25H0006808JR500 is also rated at a power dissipation of 4 Watts. This makes it a good choice for applications which require higher power dissipation levels. Additionally, it is rated to operate at temperatures ranging from -55 to +105 degrees Celsius, making it suitable for a wide range of operating conditions. Finally, its flame-retardant rating adds an additional layer of safety.

Overall, the NFR25H0006808JR500 is an excellent choice for Through Hole resistor applications. Its wide range of features and performance makes it suitable for many different RF, video, audio, voltage regulator, and filter circuits. Additionally, its thermal stability and flame-retardant properties make it a safe and reliable piece of ThermoFuse technology which can safely handle high currents for extended periods without overheating.
