Fixed Inductors

Inductors are passive electronic components used in a variety of circuits and applications. A fixed inductor, also known as a lumped inductor, is an inductor with a fixed inductance value. One of the more common types of fixed inductor is the MILS1812R-222K.

MILS1812R-222K

The MILS1812R-222K is an axial leaded, high-Q, RF inductor in a convenient 1210 form factor. It is a fixed inductor with an inductance value of 222K and features a maximum current of 840mA. These inductors are available in various values from 10µH to 1000µH and are well-suited for battery powered devices due to their low power consumption.

Application Field

The MILS1812R-222K is used in a wide variety of applications including audio circuits and power supplies. It can be used as a DC leakage inductor in a DC-DC converter and is used in high-frequency applications involving switching power supplies, pulse transformers, and EMC suppression coils. They are also used in RF circuits such as Transmitter/Receiver circuits, Low Noise Amplifiers, Mixers, Balanced Pairs, and VCOs.

Working Principle

The working principle of the MILS1812R-222K is relatively simple. It is an inductor with a fixed inductance value that is measured in Henries. When current passes through it, it produces a magnetic field which induces an electric field that opposes the flow of current in the inductor. This produces a voltage drop across the inductor which is proportional to the rate of change in the current passing through it. As the current changes, the magnetic field in the inductor collapses, inducing a voltage across the inductor which is equal to the opposite of the initial voltage.

The resistance of the inductor, also known as its “DC resistance”, is relatively low, allowing it to pass large amounts of current without overheating. The MILS1812R-222K also exhibits a high quality factor (Q = 2). This means that it is able to store energy more efficiently, resulting in higher efficiency in power applications.

The MILS1812R-222K is ideal for the low power, high performance applications and is capable of operating at frequencies up to 10MHz with excellent levels of signal integrity. It is also ideal for high-frequency RF applications due to its low loss performance.

Conclusion

The MILS1812R-222K is a fixed inductor with an inductance value of 222K and features a maximum current of 840mA. It is used in a wide variety of applications including audio circuits and power supplies as well as RF circuits such as Transmitter/Receiver circuits, Low Noise Amplifiers, Mixers, Balanced Pairs, and VCOs. The working principle of the MILS1812R-222K is relatively simple, as it uses a magnetic field to induce a voltage drop across the inductor which is proportional to the rate of change in the current passing through it.
