Fixed Inductors

Fixed inductors are passive electrical components usually used to provide inductance in circuits. They are also known as coils, chokes, or reactors. Fixed inductors are found in all kinds of electronic circuits, from power supplies to radio receivers and just about anything in between. They are essential parts of many circuits, and understanding them and how to use them is critical knowledge for any electronics engineer. The IM02SH391K is a fixed inductor manufactured by the company Murata. It is part of their Magnetically Stabilized Type Chip Coil series. This particular part is designed for use in cellular handsets and is a very small, surface-mount component designed for high-frequency switching power supply circuits. This part is a one-piece, through-hole, multi-layer surface-mount device and has a height of 0.5mm and a width of 1.5mm. It has a nominal inductance of 391 nH and has a very low typical DCR of only 0.09 ohms. The maximum operating temperature for this part is 85°C. When an inductor is placed in a circuit, it will store energy in its magnetic field when current flows through it. As the current changes, the inductor will resist the change in current. This property is called inductance, and it can be expressed in a unit called the Henry. The IM02SH391K provides a high-frequency power choke for supply lines of applications that require high noise immunity in the form of low inductance and low DCR. The inductance will limit the amplitude of current spikes in the transient periods, and it will reduce interference with other circuits in the device. The low DCR gives it the ability to handle high peak currents with minimal increase in temperature. The IM02SH391K is also designed to handle high thermal shock and high vibration, and it has excellent long-term stability as well. It is designed for use in devices which require high power supply noise immunity and is suitable for use in automotive and telecommunications equipment. Overall, the IM02SH391K is a high-quality surface-mount fixed inductor that is well-suited for use in many different applications. It is very compact and has a low DCR, which makes it an excellent choice for anyone looking to provide noise immunity in their circuits.
