Fixed inductors are used in a wide variety of applications, ranging from simple power supply designs to more complex circuits such as radio transmitters and receivers. The TO1608-1R0M is a fixed inductor used for DC-DC converters. Let’s take a look at its application field and working principle.

The TO1608-1R0M is a low-profile enclosed inductor with a power rating of 1.4A. It features large slot openings which allow it to be used in a wide range of inductor applications, from basic power supply designs to high frequency applications such as switching power supplies, LED lighting, and RF communication circuits. Its small, low-profile design makes it ideal for use in space-constrained designs, such as hand-held devices.

The TO1608-1R0M is a self-shielding, shielded inductor that provides high-frequency stop/start performance and low EMI radiation. It has a 13.55mO inductance value and a maximum DC operating current of 1.4A. This allows it to handle a wide range of impedances from 1.3 mO to 12.5 mO, making it ideal for both low-voltage and high-voltage applications.

The key to understanding the working principle of a fixed inductor is by looking at the relationship between the inductor’s inductance and the resistance of the surrounding circuit. Inductance is a measure of the degree to which a current flowing through an inductor is “opposed” by the inductor itself. In other words, the higher the inductance, the more “resistance” the inductor has to changes in the current. This effect is known as “inductive reactance”.

When a current flows through an inductor, the magnetic field surrounding the inductor produces an opposing force due to this inductive reactance. This force is then transferred to any attached circuitry connected to the inductor. This opposing force is known as the “back EMF”, and it is this back EMF that serves to limit the rate at which the current can change within the circuit.

The back EMF is generally proportional to the rate of change of the inductor current. This means that if the current in the inductor increases or decreases rapidly, the back EMF also increases or decreases in order to maintain the current at a constant level.

For the TO1608-1R0M, this back EMF helps to maintain a constant current across the inductor and prevents it from over-stressing. It also protects against input voltage and load fluctuations, making it useful in a wide variety of applications.

The TO1608-1R0M is a great choice for use in power supply designs or other circuits requiring high current and low instantaneous power dissipation. Its low-profile design makes it perfect for use in space-constrained designs, while its high-frequency stop/start performance makes it suitable for use in RF communication circuits.
