Through Hole Resistors are a type of electrical component used to regulate the flow of electricity in circuits. They are generally composed of a metal, ceramic, or plastic core, covered with an insulating material such as a insulation coatings or glass-filled epoxy, and a metal or ceramic cap, and typically mounted in a through-hole metal plate on the circuit board. There are many different varieties of Through Hole Resistors and they are used in a wide range of applications.

One of the more popular types of Through Hole Resistors is the FKN 300FR-73-4R3. This device is specifically designed for low-noise, high-frequency applications and is designed to be used as a power, temperature, or bias resistor. The FKN 300FR-73-4R3 has a rated value of 300 Ohms and a maximum current of 2 Amps. It also features a wide temperature range from -55°C to +150°C and operates over a temperature range from -55°C to +85°C. The FKN 300FR-73-4R3 is also very robust and is designed for use in harsh environments.

The FKN 300FR-73-4R3 is a Through Hole resistor with a shielded construction. It features an open-frame construction which helps to minimize the spread of any generated noise. The shielding also provides superior protection against fluctuating temperatures and electrical noise, as well as increased resistance to physical shock and vibration. The FKN 300FR-73-4R3 is designed to operate within the frequency range of 1 megahertz to 20 gigahertz.

The FKN 300FR-73-4R3 is most often used for signal and power line protection to stabilize DC/AC power and video signals, and is often employed in various medical, industrial, aerospace, communications, and automotive applications. It is also used to protect sensitive components from over- and under-voltage conditions, and is suitable for use in applications that require high-current, low-voltage, and noise suppression protection. The FKN 300FR-73-4R3 is also widely used in military applications, as it offers superior levels of resistance to voltage spikes and serves as an effective source of noise suppression.

The working principle of the FKN 300FR-73-4R3 is based on Ohm’s Law, which states that the current through a resistor is proportional to the voltage applied to it as long as the component temperature remains constant. The resistance of the FKN 300FR-73-4R3 is 300 Ohms, and the maximum current is 2 Amps. This means that for every 1 Volt of voltage applied to the resistor, 2 Amps of current will flow through it. As the temperature of the component increases, the resistance of the device decreases, and therefore the current through the device increases.

In conclusion, the FKN 300FR-73-4R3 is an effective, reliable, and versatile Through Hole Resistor, which is capable of providing excellent noise and temperature suppression for a wide range of high-frequency applications. It is designed to operate within the frequency range of 1 megahertz to 20 gigahertz and is designed for use in a wide range of applications that require superior levels of protection from over- and under-voltage conditions, as well as noise suppression.
