Fixed Inductors

Fixed inductors are electronic components made primarily of wire. Those wire consists of a coil, and that coil is wound around either a ferrite core or an iron core. They are used to filter, store, or deliver electrical signals. Fixed inductors can also be used for radio tuning, pulse shaping, and timing circuit applications.

The 4232-121K application field and working principle involves one of the most common types of fixed inductors. The 4232-121K is a one-turn, molded-ferrite core, SMD mounted, small-size power transformer. It has an inductance of 0.2 mH, and is designed to produce a high flux density. With low saturation flux density and a useful operating range of over -40 to 150 degrees Celsius, this inductor can operate in both extreme temperatures and humid environments.

This small fixed inductor is extremely efficient in filtering and shielding. It works best when used to identify, reject, or amplify small signal frequencies. When placed along with other electronic components, it produces an output signal with more power and a more accurate frequency, which eliminates unnecessary noise. It can also be used as a voltage regulator, allowing a device to convert an AC current into a DC current.

The operation of the 4232-121K is based on two types of principles. The first is core loss, which occurs when the core material absorbs a signal’s energy as heat. The second is eddy current losses, which is when an induced current flows through the total material’s resistance. These two principles cause a drop in the efficiency of power delivery or conversion.

In addition to filtering, the 4232-121K can also be used as an energy storage device. This is done through the use of a rectifying diode. By transmitting an alternating current through the diode, it can store energy in form of an electromagnet. By adjusting the output transformers winding ratio it is possible to turn a linear voltage into a pulse train.

From filtering to storage, the 4232-121K is a versatile fixed inductor with a range of applications. With its ultra-small size it can be used in almost any space constraint location. It provides strong filtering and shielding that performs under extreme temperatures and humid conditions. With its low saturation flux density and wide operating range, this miniature inductor produces high-quality signals.
