Fixed Inductors: The ER1840-22JR

Inductors are one of the essential components used in most electronic circuits. There are many different types of inductors, including fixed inductors, adjustable inductors, and variable inductors. Fixed inductors consist of coils of conductor, usually copper wire, wound around a core. The ER1840-22JR is a type of fixed inductors with high-performance characteristics.The ER1840-22JR is a high-frequency axial inductor made of military-grade two-bobbin construction. It has a low profile height and a robust construction to support a low profile fitment to circuit boards. The inductance range is from 2.2 μH to 4.7 μH. The inductance tolerance is ±5%, and the current rating is 10 A with a saturation current of 14.5 A.The ER1840-22JR is capable of operating in temperatures up to 175°C and is suitable for reflow soldering. It can be used in a wide range of applications, including power supplies, signal processing, power management, and other applications.The ER1840-22JR has a wide operation range (i.e., from low- to high-current operation). It is also very reliable and has excellent electro-magnetic compatibility.The basic working principle of the ER1840-22JR is faraday\'s law of induction. This law states that the induced emf in a coil is proportional to the time rate of change of the magnetic field passing through it.When an alternating current passes through the winding on the core of an ER1840-22JR, an alternating magnetic field is set up in the coil. This alternating magnetic field sets up an alternating electric current in the same direction in the coil, which in turn produces an alternating voltage across the coil. This voltage, which is also known as the induced voltage of the coil, is proportional to the current in the coil. The ER1840-22JR then acts as a conductor of the induced current.The ER1840-22JR is a high-performance inductor that is suitable for a wide range of applications. Its robust construction and low-profile height make it an ideal choice for use in signal processing and power management applications. By understanding its application field and working principle, the user can make sure that the ER1840-22JR is suitable for their application.
