Fixed inductors are electronic components used to resist changes in electric current. The IMS05WDRU821K40 is a type of fixed inductor that has a range of applications and works on a specific principle.

The device has an inductance of 0.47 uH, a current rating of 2.2 Amps, and a maximun DC resistance of 0.10 Ohms. It is a shielded surface-mount, ferrite chip inductor, meaning that it consists of a ferrite rod surrounded by a metal shield and designed to be soldered onto a metal PCB. The ferrite rod carries the majority of the inductance, while the shield helps reduce any unwanted current leakage. The 3.1mm x 2.1mm size of the inductor allows it to be soldered onto PCBs that have a 0.5mm pitch or higher, making it useful for devices which require a large number of components in limited board space.

IMS05WDRU821K40 inductors can commonly be seen in DC power supply and filter circuits, used to allow DC current to pass through while blocking AC current. The fixed inductors are also used in radio frequency (RF) circuits to deal with RF signals at frequencies up to 500MHz. There can also be applications in automotive electronics where the inductor’s protective shield is preferable due to the engagement of fluids, oil, temperature, and other environmental factors. Moreover, these components are typically used in devices that require fast turn-on and turn-off times, such as medical imaging systems, medical device accompanying boards, communication systems, RADAR systems, video cameras, hearing aids, and air-breathing control systems.

Fixed inductors work based on the principle of Lenz’s law. According to Lenz’s law, when an electric current passes through a conductor, an opposing magnetic field is created around it. As the current increases, the opposing magnetic field becomes stronger, thus increasing the resistance in the conductor. Consequently, the amount of current flow is reduced. This is the principle behind the IMS05WDRU821K40 inductor. When current passes through the ferrite rod, the opposing magnetic field causes the inductor to resist changes in current levels, thus ensuring a consistent and stable current flow.

IMS05WDRU821K40 fixed inductors offer low profile and wide temperature range, making them highly versatile components. The high-temperature alloy symbols which are present in the device make it suitable for use in a variety of industrial and consumer applications. Furthermore, the robust copper shields and leads of the inductor increase its heat dissipation capabilities. This is advantageous in applications where resistance to temperature fluctuations is needed. In summary, the IMS05WDRU821K40 components can be commonly found in DC power supply and filter circuits, radio frequency applications, automotive electronics and medical devices. Furthermore, these fixed inductors work by making use of Lenz’s law, which specifies the relationship between electric current and magnetic filed intensity.
