IM02SHR15J

Fixed inductors generally fall into four main categories, depending on their working principle and application field. IM02SHR15J is one of such inductors and primarily finds application in RF circuits. In this article, we look at all its relevant specifications and its working principle.

Specifications

The size of this inductor stands at 2.3x2.3x1.2 mm, making it extremely compact and suitable for tight applications. It can handle power of up to 1.65 W. Furthermore, its rated DC current stands at 800 mA and the DC resistance is 1.2Ω. The inductance of IM02SHR15J is between 4.7 and 10 uH and 20% tolerance is maintained for it. Its self-resonant frequency is in the range of 1.1-1.4 GHz, and the insulation resistance is 1000 MΩ.

Working Principle

The working principle of this fixed inductor relies on the Faraday law of induction. This law states that an electromotive force is induced in any closed circuit whenever there’s a change in magnetic flux. This induced force can be computed by multiplying the rate of change in the magnetic flux with the number of turns of the circuit.

In the case of IM02SHR15J, the electric current flowing through the inductor induces a magnetic flux, which is determined by the number of turns the inductor has. According to Faraday’s law of induction, an induced electromotive force is created in the closed circuit whenever the magnitude of the magnetic flux changes. The magnitude of this electromotive force is equal to the product of the rate of change of magnetic flux and the number of turns of the circuit.

Advantages

IM02SHR15J has numerous advantages over other types of fixed inductors. To start off, its low DC resistance results in low power consumption and higher efficiency. This is also a result of its small size. Furthermore, due to the 2.3x2.3x1.2mm body size of this inductor, it can be easily used for tight spaces, which is especially advantageous when dealing with large-scale integration. Lastly, since this inductor can handle up to 1.65W power, it is a great choice for high power applications.
