Fixed inductors are pieces of electronic equipment with a range of uses. They are available in a variety of shapes and sizes and can also be customised to meet specific requirements. The LBR2012T470M is one example of a fixed inductor and it has numerous applications. Additionally, the working principle of a fixed inductor is not overly complicated and can easily be understood.

This particular fixed inductor is an individually packaged, anti-static device with an encapsulated ferrite core. It is designed for use in low pass filtering applications and can handle an average current of 4A with a maximum peak current of 6.3A. The 970mOhms resistance ensures that an appropriate voltage is supplied and the tan delta at 25°C is 0.04. It has a rated DC voltage of 100V and belongs to the radial leaded range of fixed inductors.

In terms of size, the LBR2012T470M is quite unique. It has a relatively low profile and stands at just 2.5mm tall. This makes it very small and unobtrusive when used in more confined spaces, such as PCs or laptops. Additionally, it has a 40µH inductance and a saturation current of 8A/10kHz.

In determine how fixed inductors work, it is useful to consider the six basic elements that make up electrical circuits (current, voltage, resistance, inductance, capacitance and power). When electrical current passes through a conductor (such as a wire), the net electrical potential energy (voltage) is established, which will be spread out evenly throughout the circuit. However, for inductors, this isn’t the case; instead, the voltage is focused into a small area - usually at the junctions between the conductors. This is due to the inductance of an inductor, which increases when alternating current passes through it.

Inductors store their energy in the form of a magnetic field, which is created when the electric current passes through it. This ensures that an alternating current will continue to increase until the magnetic field is strong enough to oppose it. This produces a rolling effect, with the current oscillating backwards and forwards as it is passed through. In the case of the LBR2012T470M, this translates into a low pass filtering effect which is used to eliminate unwanted noise in audio or visual signals.

In addition to their low pass filtering capabilities, fixed inductors are also used as chokes and transformers. When used as chokes, the inductors keep the electrical current within a circuit to a minimum. This is because the magnetic field surrounding the inductor restricts the flow of current. When used as a transformer, the inductor introduces an alternating current into the circuit which can be amplified and converted into direct current, allowing it to be used for a range of purposes.

The LBR2012T470M fixed inductor is a useful piece of electronic equipment, with a range of applications. It can be used as a low pass filter, to reduce noise in electronics, as a choke to limit electrical current, and as a transformer to convert alternating current into direct current. Additionally, the working principle of fixed inductors is quite straightforward, with energy stored in a magnetic field being used to create an oscillating current. This makes the LBR2012T470M a great choice for any electronic system.
