Fixed inductors are devices used to store electrical energy in the form of a magnetic field. They are typically constructed from a coil of wire and a ferrite core, which acts as the inductor’s magnetic core. The 103R-220KS type is a surface-mountable fixed inductor that is commonly used for current-sensing applications in communications and automotive electronics.

The 103R-220KS operating principle is based on Faraday’s law of electromagnetic induction. It states that a voltage will be induced in a conductor when it is exposed to a changing magnetic field. In this case, the changing magnetic field is produced by the inductor itself, which creates an oscillating magnetic field when an electrical current passes through the wire coil. This induces a voltage in the attached circuit, which can be measured to determine the current passing through the inductor.

The 103R-220KS fixed inductor is designed to provide excellent current-sensing accuracy for low-frequency signals. It is available in a variety of sizes to fit different applications. For example, the LAL03RS-11-02 and MCQ03RT-11-03 models have a 10-µH rating and an inductance tolerance of ± 20%, while the UPF05RT-11-02 offers a 30-µH rating with a ±30% inductance tolerance. The UPF05RT model is also available in three different sizes, 1, 2, and 3, to accommodate different PCB layouts.

This fixed inductor can be used in a wide range of applications. The most common uses of the 103R-220K include current-sensing applications in automotive and communications applications. For example, it can be used to measure the current in automotive powertrain systems such as electric vehicles and hybrid vehicles. It is also used in communications for current-sampling applications, such as for measuring the current used in optical communications where there are few other options available. The 103R-220K is also used in motors as a sensing element for controlling current or detecting the presence of an electric field.

The 103R-220KS fixed inductor comes in a low-profile package that allows easy mounting on any type of printed circuit board (PCB). It provides excellent accuracy and reliability for current-sensing applications in communications and automotive electronics. Its tight inductance tolerance makes it ideal for designing high-precision circuits, while its low-profile packaging makes it ideal for use in tight spaces. This makes the 103R-220KS a popular choice for many engineers who require a reliable and accurate current-sensing or voltage-sampling device.
