Through Hole Resistors are commonly used for simple impedance control, frequency response customization, as well as for surge and pulse current protection. Within the context of resistors, the FKN200JR-73-3R is a particularly powerful type, designed to provide a wide range of resistances, allowing for total control of current and voltage. It is constructed with both an axial leaded and a radial version, with both styles interchangeable, so that users can find the ideal solution to their needs.

The FKN200JR-73-3R consists of a ceramic core and metal or alloy terminals. A standard resistor most widely used is constructed of a single flat aluminum-nickel contact element, with an alloy disc as the contact element. The contact element is mounted onto a ceramic core, which has a metal or alloy terminal that protrudes from one side.The other side of the resistor, referred to as the ‘back-plate’, is normally formed from a coil of 0.03 inch (0.76mm) thick metallised plastic film with two metal tabs. The tabs are connected to the metal or alloy terminals.

The FKN200JR-73-3R is built as a variable resistor, with the resistive element between the two terminals varied by adjusting the piston. This piston is connected to a control knob, which when adjusted causes the slider connected to the piston to move up or down the resistive element, adjusting its resistance accordingly.The FKN200JR-73-3R also features a flame-retardant construction to meet the needs of a variety of applications, as well as a highly durable and reliable design.

One of the primary applications of the FKN200JR-73-3R is as a potentiometer. Potentiometers control the amount of current and / or voltage passing through an electrical component. Used to adjust the voltage, current, resistance or impedance of a circuit, they are often used in conjunction with other components such as fixed resistors.

The FKN200JR-73-3R is also widely used in amplifier applications with high input impedance. Because of its variable resistance range, it can be used to adjust the input impedance of the amplifier. Additionally, its resistance range can be preset to the input impedance of the amplifier in order to ensure that the signal is properly amplified.

The FKN200JR-73-3R is also used in surge or pulse current protection in power electronics. As it has a high power handling capacity, it can be used in applications such as overcurrent protection, where it will provide a large resistance value that will prevent the excess current from reaching the device under protection. Additionally, it can be used in applications such as short-circuit protection, where it will provide a large resistance value to limit the current flowing through the device.

In summary, the FKN200JR-73-3R Through Hole Resistor is a powerful and reliable component for many electronics applications. Its range of resistances, flame-retardant construction and high power handling capacity make it versatile and durable, allowing it to be used for a wide range of applications.
