Fixed Inductors

When it comes to passive components like inductors, fixed inductors are among the most common types used in electronic applications. Fixed inductors are inductors with a fixed values of either inductance or current, and can be used for many applications. A good example of a fixed inductor is the RLB9012-820KL.

RLB9012-820KL Application Field

The RLB9012-820KL is a typically air-core fixed inductor that offers a wide variety of uses in a variety of fields. It can be used as part of an RF filter, an audio crossover network, a band-stop filter, and a DC/DC converter. Other applications include power-line EMI filters for electronics, as well as for automotive use. It can also be used as an impedance matching component in an amplifier or other circuit. The type of application depends on the specific requirements.

RLB9012-820KL Working Principle

The working principle of the RLB9012-820KL is the same as for any other inductor. It has a core made of air, and the core is usually wrapped in multiple coils and then encapsulated in resin or silicone. When current flows through the coil, a magnetic field is generated, and this field induces a voltage across the coil. This caused the inductor to resist sudden changes in current, thus creating a “smoothing” effect on the signal.

The inductance of the RLB9012-820KL is 820uH, and it has a maximum operating voltage of 32V. This is a fairly standard rating for an air-core inductor of this size, and it will perform well in most applications. The RLB9012-820KL has a low DC resistance of 0.06Ω, meaning that it has very low losses when power is applied. This also allows it to operate at a higher current.

Conclusion

The RLB9012-820KL is a great example of a fixed air-core inductor that can be used in many applications. It has a high inductance of 820uH, a maximum operating voltage of 32V, and a low DC resistance of 0.06Ω. This makes it a perfect choice for RF filters, audio crossovers, band-stop filters, DC/DC converters, power-line EMI filters, and impedance matching components. It is a highly versatile and reliable component, and it is well suited for many types of applications.
