Fixed Inductors are electrical components used to store energy in electric and magnetic fields. Featuring low-impedance and quick current flow, inductors are ubiquitous in today’s circuit designs – from communications to consumer electronics, automotive design to aerospace engineering. IM04BH390J inductor is a component used often in those applications, and it is worth understanding a bit about its features.

The IM04BH390J Fixed Inductor has a rated inductance of 0.39μH and a rated DC current of 1.1A. It is constructed of ferrite, comes in a 1210 package, and has a wide operating temperature range of -40- 105 degrees Celsius. It features a low profile and a high-frequency operating range of up to 500MHz, allowing it to find a place in a variety of different circuit designs.

The IM04BH390J Fixed Inductor can be found in many applications, ranging from high-frequency switching circuits to low-noise communications, and from consumer electronics to automotive designs. That versatility comes from the inductor’s ability to control current flow–generally it does not act as a resistor or capacitor does, which limits current flow; instead, it depends on a combination of impedance, self-resistance, mutual inductances, plus the inductance itself. Thus, it can help in managing the flow of electricity in the circuit.

The working principle of the IM04BH390J Fixed Inductor consists of two main components. First, it has an internal magnetic field that will create an opposing magnetic field when the current changes, an action referred to as ‘back-EMF’. This back-EMF will produce a counter electromotive force (EMF) that opposes the main current. Second, it also consists of self-resistance, referred to as inductance, which provides proportionality between the current flowing through it and the applied voltage.

In summary, the IM04BH390J is a versatile Fixed Inductor that comes with many features to assist in a range of different applications. Its wide operating range and high-frequency characteristics make it a good choice for communication-based designs, as do its relatively low profile and relatively low internal resistance. Furthermore, the internal magnetic fields and self-resistance of the IM04BH390J work together to help manage the current flow; and ultimately, this is one of the major advantages of using this type of inductor in a variety of circuitry.
