Through Hole Resistors are commonly used devices within the electronics industry due to their ability to provide a predictable, dependable and well-defined resistance. A well known type of Through Hole Resistor is the CFR200JR-73-300R, which is a device designed for analog and digital applications. This article will explore the application field and working principle of the CFR200JR-73-300R.

The CFR200JR-73-300R is an axial leaded, type-C, non-inductive, thru-hole resistor. It is constructed from high-resistance, low-wattage Nichrome alloy and coated in a Flame Retardant Resin. It is designed for applications such as voltage dividers, filter networks, current sensing, frequency modulation, timing circuits, regulated power supplies and bridge circuits.

The resistance range of the CFR200JR-73-300R is a very wide 15k ohms to 220k ohms, with a power rating of 5 Watts. It can also operate at temperatures ranging from -55 to +150°C, with an acceptable voltage up to 600 VAC. These features combined make it ideal for a wide range of industrial and home applications.

The working principle of the CFR200JR-73-300R is based on Ohm’s Law, which states that the current flowing through a resistor is directly proportional to the voltage applied across it. This means that if the voltage is increased, then the resistance of the resistor will increase accordingly. Likewise, if the voltage is reduced, then the resistance will decrease. By controlling the application of the voltage, the resistance of the CFR200JR-73-300R can be adjusted accordingly.

The CFR200JR-73-300R has a unique design that allows it to be used in both on-off and adjustable circuit applications. The ohm range can be finely adjusted using the adjustable rings that are located at the two ends of the resistor. The moveable ring will change the resistance by altering the contact force between the two strips of resistor material, which will in turn alter the resistance of the resistor.

The CFR200JR-73-300R is designed to be a low-cost, reliable, and highly adjustable resistor that is suitable for a wide range of industrial and home applications. It is reliable and efficient and can easily be incorporated into complex circuits. The adjustable rings enable the resistance to be fine-tuned and the low-wattage Nichrome alloy ensures that it can handle the output power of most applications.

In summary, the CFR200JR-73-300R is an axial leaded, type-C, non-inductive, thru-hole resistor. It is designed for applications such as voltage dividers, filter networks, current sensing, frequency modulation, timing circuits, regulated power supplies and bridge circuits. It has a resistance range of 15k ohms to 220k ohms, a power rating of 5 Watts, and can operate at temperatures ranging from -55 to +150°C. It is designed to be a low-cost, reliable, and highly adjustable resistor that is suitable for a wide range of industrial and home applications, and its working principle is based on Ohm’s Law.
