Fixed inductors are components used in electronic circuits to provide inductance, allowing circuits to pass desired signals and store energy. The 1812-820J Inductor is a specific type of fixed inductor, utilizing two layers of winding to create the inductance necessary for the circuit. The primary applications for the 1812-820J inductor are in noise filtering, high-speed switching applications, and in RF switching circuits. The inductance of the 1812-820J is temperature-stable thanks to its two-layer winding, making it perfect for applications in highly oscillatory circuits or those which require the passing of high-powered pulses.

The 1812-820J employs ferrite or air core construction, both of which provide excellent stability to the inductance. The DC resistance of the 1812-820J is also very low, allowing for excellent current carrying capability. Additionally, the 1812-820J is housed in a molded plastic case to further reduce possible sources of inductance drift that come with circuit temperature changes.

The 1812-820J utilizes a two-layer winding to make it ideal for applications requiring precise inductance levels. The two-layer winding utilizes two cores wound in opposite directions. This winding configuration enables the 1812-820J to provide more stable inductance than a single layer winding, allowing for more accurate filtering and better signal integrity in circuits with a high pulse rate. This structure also creates a higher Q factor, which makes it more efficient for high speed switching applications.

In RF circuits, the 1812-820J is used to prevent undesired signals from interfering with the desired frequency. The inductor helps to filter out incoming noise while allowing the desired signal to pass through uninterrupted, allowing the circuit to successfully complete its task. The two-layer core also helps to reduce signal interference, further improving signal integrity in the circuit.

The 1812-820J is perfect for high-speed switching applications due to its high-Q structure. The high Q-value ensures that the inductance changes over time and frequency are minimal, allowing for stable current pulses in the circuit. This helps to reduce errors in the circuit, leading to better accuracy in switching operations and fewer system timeouts.

Overall, the 1812-820J fixed inductor is a valuable component for numerous applications. By utilizing a two-layer core winding, the inductor provides excellent stability and signal integrity, while also reducing noise interference. The 1812-820J is well suited for noise filtering, RF switching, and high-speed switching applications, allowing for a wide range of applications. Its low DC resistance and high Q-factor also makes it an excellent choice for applications requiring accurate and stable current pulses.
