2150R-01G

Fixed Inductors

Inductors, typically seen in common electronic circuits, are electrical components that employ an inductance in order to conduct electric current. A fixed inductor, such as the 2150R-01G, has a set inductance value, although additional capacitors can be wired into the device in order to function as a variable inductor. By understanding theand application field and working principle of the 2150R-01G, the engineer can effectively incorporate this device into a circuit.

The 2150R-01G belongs to a family of fixed inductors which make use of a miniaturized wire coil to generate a magnetic field as current passes through it. This conversion of electric energy into magnetic energy is what provides the inductor its desired function: the opposition of a change in the electric current passing through it. The 2150R-01G has a nominal inductance value of 750 mH, and its wire coil measures at a diameter of 6.7mm and length of 14.7mm.

Due to its small form factor, the 2150R-01G lends itself to incorporation within high-density circuit boards such as those found in TV and radio tuners. Other applications include noise suppression, filtering devices, and for coupling and decoupling signal paths. In power supplies, the 2150R-01G acts as a differential mode inductor for power-line communication and power-over-Ethernet.

In order to ensure that the 2150R-01G functions to its greatest efficiency, considerations must be given to the device’s mounting. In order to maximize performance, a PCB layout that places the inductor in close proximity to the input and output terminals should be utilized in order to reduce inductance loss and surface noise. Research has shown that using an imprinted copper plane or heavy copper trace underneath the inductor can reduce thermal impedance.

The working principle of the 2150R-01G is based on Faraday’s Law of Induction. This law states that the polarity and magnitude of the induced voltage in an inductor is dependent upon the rate of change of the current through it. By means of this relationship, the 2150R-01G is able to oppose any changes in current passing through its terminals, a feature that makes it ideal for noise suppression, signal coupling, and for providing stability to the electric circuit.

The 2150R-01G fixed inductor is especially well-suited to working within high-density circuit boards that require reliable and high-performance inductance. By employing the principles of Faraday’s Law, this device is able to oppose changes in current, making it ideal for noise suppression, signal coupling, and power-line communication.
