Through Hole Resistors

Through hole resistors, also known as leaded or axial resistors, are one of the most common resistor types. They are typically used in circuits operating at relatively low frequencies, mostly in STB and electrical engineering applications. The CFR3WSJT–73–18R is an axial resistor component that has a wide range of applications and it is important to understand its working principle.

CFR3WSJT–73–18R application field and working Principle

The CFR3WSJT–73–18R is a large size axial resistor with a power rating of 15W. It has a nominal resistance of 1Kohm and a tolerance of ± 5%. It is typically used in STBs and electrical engineering applications. These applications include:

• Power amplifiers
• Antenna amplifiers
• Broadcast and cable receivers
• Filters
• Analog ICs (integrated circuit)
• Power supplies
• Instrumentation

The CFR3WSJT–73–18R resistor has a cylindrical, non-inductive winding. It is composed of a high-temperature, high-resistance wire, encased in a conductive material. This conductive material is a combination of tungsten, steel, and silver, and it serves to provide electrical insulation while also dissipating heat effectively. The resistor has two wires on either side of the cylinder, which are connected to the electrical power source. The resistive value of the component is determined by the size of the wire and the amount of resistance in the material.

When an electrical current flows through the CFR3WSJT–73–18R, the heat produced is dissipated by the material and wire. This heat is then transferred to the surrounding environment. The resistive value of the component is reduced as the temperature increases, thus allowing for more current to flow.

CFR3WSJT–73–18R resistors are highly reliable components, and they do not require regular maintenance. They can also be used in circuits that require high-powered signals. This makes them ideal for use in STBs and other high-frequency applications.

Conclusion

The CFR3WSJT–73–18R resistor is a versatile component with a wide range of applications. It is a high quality, reliable, and efficient component, which makes it a great choice for a variety of projects. It is also a great choice for STB and electrical engineering applications, as it can handle high-powered signals without requiring regular maintenance.
