Fixed Inductors

Fixed inductors are electrical components that are used to store energy with the help of a magnetic field. These components usually appear as coils of wire, though they can also come in a variety of shapes. Fixed inductors are typically used in electronic circuits to help regulate the flow of electrical current and to filter out specific signals.

The 0603-16NJ application field is a fixed inductor that is externally mounted and sized at 0603, or 6mm by 3mm in length and width respectively. This fixed inductor operates with a primary current of 5A and a maximum ripple current potential of 1A. It can handle temperatures of -40 to +105°C.

The 0603-16NJ working principle is based on Faraday’s Law of Induction. This law states that a change in magnetic flux through a conductor creates an induced electric current. As such, an inductor acts as a “silent” resistor in a circuit that is used to provide opposition or impedance to the change of electric current. The magnetic flux is produced by the inductor’s coil and is accompanied by an electric current inside of the coil.

An ideal inductor follows the equation L=N^2×A×μ (L is inductance; N is number of turns; A is the cross-sectional area of the coil; and μ is the magnetic permeability of the core). For this equation, a higher number of turns will produce more inductance, as will a larger core and an increase in the cross-sectional area. This equation thus allows engineers to calculate the necessary parameters for a custom inductor.

Inductors are important components in a variety of electronic devices, from televisions to industrial power supplies. They are used to help filter out different portions of a signal, which is important for isolating desired audio or video frequencies from the rest of the noise in a system. They can also be used to limit the power supplied to a delicate circuit, helping to prevent overloading.

The 0603-16NJ fixed inductor is just one example of the many types of inductors available today. While its working principle and application fields are similar to other inductors, unique characteristics such as number of turns, size, and temperature rating will make it particularly useful for certain applications.
