Review JOHNSON Roller Inductor Parts Project
The 229-202 Johnson Roller Inductor is a high-quality electrical component designed for use in a wide range of applications. This inductor is a roller type, which means it features a cylindrical core wrapped with multiple layers of copper wire. The roller design allows for a more uniform distribution of magnetic field, resulting in improved performance and reliability.
The 229-202 Johnson Roller Inductor has a core material made of ferrite, a type of magnetic material known for its high magnetic permeability and low electrical conductivity. This makes it an excellent choice for applications that require a high inductance-to-size ratio and good energy storage capabilities.
The inductor has a total inductance of 202 microhenries, which is suitable for many electronic circuits, such as filters, power supplies, and oscillator circuits. The maximum operating temperature is 150 degrees Celsius, ensuring its performance under various operating conditions.
The 229-202 Johnson Roller Inductor is available in a standard 5mm diameter and 15mm length, making it easy to incorporate into most electronic designs. Its compact size and high performance make it an ideal choice for space-constrained applications, such as portable electronic devices and battery-powered equipment.
The inductor is also capable of handling a maximum current of 2.5 amperes, ensuring it can handle the power requirements of most electronic circuits. Its resistance to electrical noise and interference makes it an excellent choice for applications that require high signal integrity, such as in communication systems and data transmission.
In summary, the 229-202 Johnson Roller Inductor is a versatile and high-performance electrical component that is suitable for a wide range of applications. Its roller design, ferrite core, and high inductance make it a reliable choice for applications that require energy storage, noise reduction, and improved signal integrity.

Details:
In the pictures you can see some that I missed, so it needs further cleaning perhaps a toothbrush and non-abrasive toothpaste. The roller inductor has some scratches, missing paint, blemishes and discoloring. While sitting in my project box it got dusty and some light corrosion on side of coils, most which I wiped off with alcohol a rag.
E f Johnson roller inductor as is parts project this sale for a knob and shaft couplet pictured are included in I bought some time ago intending to build home brew antenna tuner but didn't get around it.
