Fixed Inductors

CLQ4D10NP-4R7NC is a fixed inductor, a passive two-terminal electrical component that stores energy in its magnetic field. It is much like a capital resistor, except the power supplied to a inductor creates a magnetic field instead of a current flow. Fixed inductors are widely used in applications such as motion control and robotics, automotive, telecommunications, and switching adaptors.

Several types of fixed inductors can be divided into air core, powdered iron core, ferrite core, thin film core, and multiturn windings. The inductance of a coil, measured in henries, is determined by the material and geometry of the core, the number of turns in the coil and the type of winding.

CLQ4D10NP-4R7NC fixed inductors are spool-wound on a plastic bobbin and constructed using compressed ferrite magnets. They are packaged in a 2 mm × 8 mm × 7 mm case and with a tolerance of ±5%. The CLQ4D10NP-4R7NC fixed inductor has an inductance of 4.7µH, an rated current of 10A, and a SRF of 29MHz. Additionally, it has an operating temperature of -40 to 105℃, and can be used in a wide range of applications such as DC-DC converters, automotive, audio, and medical devices.

The working principle of a fixed inductor is based on Faraday’s Law of Induction. Faraday’s Law states that when a changing current flows through a conductor, it creates a magnetic field in the conductor that in turn induces a voltage in the conductor. Fixed inductors take advantage of this principle to produce inductance in the form of a magnetic field.

This induced voltage is often referred to as self-inductance since it induces a current in the same circuit from which it has been generated, resulting in an inductance. The inductance created by a fixed inductor varies depending on the number of turns in the coil and the shape and size of the core.

The core of a fixed inductor also helps to keep the inductance consistent. Core materials have a permeability, which is the measure of how well a material can be magnetized, and the higher the permeability, the higher the amount of inductance created. The amount of inductance (measured in henries) is proportional to the number of turns in the coil and the permeability of the core.

Finally, CLQ4D10NP-4R7NC fixed inductors offer low cost, reliability, and efficiency. Their low-costs make them ideal for applications such as DC-DC converters, power supplies, and automotive. Furthermore, their reliability and ruggedness make them suitable for high-vibration and temperature applications. In addition, they are designed with a high efficiency, allowing them to dissipate less heat and provide better performance.
