Resistors are electrical components designed with a single purpose – to create or modify an electrical circuit by providing a resistance value, allowing the control of electrical flow. Through-hole resistors are resistors that have leads (or pins) that extend via the component’s body into the PCB holes. One of these through-hole resistors, the FRN25JR22, can be used in a variety of applications and has a distinct working principle.

Applications for the FRN25JR22 Through-Hole Resistor

The FRN25JR22 is a significant power rating resistor that can act as a current limiting device in a wide range of power-supply topologies. This can be particularly useful in high-power circuits as its resistance values range from 0.1 to 10 megohms while its wattage ratings range from 5W to 15W. These devices have excellent stability, providing greater maintenance and reliability for the circuit they’re installed in.

The FRN25JR22 is commonly used in a range of automotive applications, including car cigarette lighters and controllers for HVAC or climate controls, engine control units, alternator control, and exhaust gas recirculation. It can also be a reliable component in medical equipment designs, allowing a low-current operational mode without compromising performance. This through-hole resistor is also used in telecommunications applications and in the high-power consumer electronics, lighting, and audio systems.

Working Principle of the FRN25JR22 Through-Hole Resistor

At the core of the FRN25JR22’s working principle is its power rating and resistance values, which generate a precise amount of electrical current and control the power supply’s topology. Essentially, this type of through-hole resistor effectively imposes a limit to current flow. It works by presenting a specific, fixed resistance to a current circuit\'s flow. This resistor then reduces the current to the most suitable power level for the device.

Given its power rating and resistance values, the FRN25JR22 can be connected to a voltage source to produce an electrical current through the resistor. That current produces a precisely calculated amount of heat which is dissipated from the device, allowing the resistor to effectively limit the current and thus, the voltage supplied to the load. This working principle makes the FRN25JR22 a reliable choice for power supply circuit applications.

Conclusion

The FRN25JR22 is a through-hole resistor with great power ratings and efficient resistance values. It is primarily designed for power supply-based circuit designs, where its working principle makes it a valuable component in controlling the voltage to the load. This resistor is also suitable for a range of automotive and medical applications, as well as for telecommunications and consumer electronics.
