Through-hole resistors are commonly used in electronics. They are small, lightweight, and relatively inexpensive components which can be soldered to a printed circuit board (PCB) to provide a reliable, low-cost electrical connection. The FKN100JR-73-91R (hereafter referred to as the FKN resistor) is a particularly popular through-hole resistor; specifically, it is a precision thick-film resistor designed for low-power, low-voltage applications. It is also highly reliable in normal environmental conditions.

The FKN resistor is constructed from resistance elements which are screen-printed and fired onto an alumina substrate. An additional ceramic terminal is used to attach the resistor to the component leads for soldering the component to the board. This construction makes the FKN resistors especially robust compared to standard through-hole resistors.

An FKN resistor is compatible with any application which requires a through-hole resistor with a resistance in the range of 0.1Ω to 1MΩ, a temperature coefficient of resistance between ±100 parts-per-million (ppm) and ±1500ppm (the actual resistor should meet the application\'s needs), and a voltage rating between 0.1V to 70V. The value of the resistor should be printed on the resistor body and will be expressed in the unit of ohms. For example, a resistor marked “200” indicates that the resistor is 200ohms.

An FKN resistor’s primary application areas are in sensitive analog and digital circuits, such as metering, sensing, timing, and control circuits, as well as other low-voltage/low-power applications. Due to its unique construction, the FKN resistor is also suitable for high-temperature (up to 315°C) and pulsed-current applications. It is also well-suited for thin, high-density PCBs since the metal-cup design allows the resistor to be closely spaced with other components.

The FKN resistor works according to Ohm’s law, which states that the current passing through a resistor is proportional to the voltage across the resistor. In a circuit, this means that when a voltage is applied, a current can be measured through the resistor. This current is regulated by the resistor, based on the application-specific resistance value of the resistor. When in a series circuit, the resistance of the resistor is added to the total resistance of the circuit. Finally, in a parallel circuit, the current is split proportionally based on the resistance values of the resistors.

In summary, the FKN100JR-73-91R through-hole resistor is a thick-film resistor that is designed for low-power, low-voltage applications. It is reliable, low-cost, and can operate in a wide range of temperatures. Its resistance is compatible with any application which requires a value between 0.1Ω and 1MΩ. The FKN resistor works according to Ohm’s law, and functions depending on the specific resistance value of the resistor. Thus, it is an ideal choice for a wide variety of low-power circuit applications.
