Fixed Inductors play an essential role in all types of electronic circuits as they are used to store electrical energy in the form of a magnetic field. The SCRH4D18-390 is a particular type of fixed inductor developed by King Koil Incorporated. It is designed for high frequency applications and is suitable for communications systems, portable care-based products, home entertainment units, data communications, GPS applications and energy management systems.

The SCRH4D18-390 is manufactured using surface mount technology, meaning it takes up very little board space. This makes it particularly useful for portable and space-saving electronic circuits. The device features excellent electrical and mechanical performance, with an inductance tolerance of ±3%.

The SCRH4D18-390 operates on the principle of electromagnetic induction. An alternating current passing through a coil of wire generates an oscillating magnetic field. This field then induces a corresponding electric field in the near vicinity of the coil to induce a voltage. The voltage generated is proportional to the rate of change of the current induced, which is, in turn, proportional to the frequency of the magnetic field.

The SCRH4D18-390 fixed inductor features a ferrite core housing and magnetic shielding to reduce electrical interference and radiated losses. The windings around the ferrite core are wound with a special polyamide-imide enameled wire, which results in smoother operation, a low temperature coefficient and excellent di/dt performance. The inductance value of the device is set at 390 nH.

The same principles of electromagnetic induction used for the SCRH4D18-390 can be applied to other fixed inductors. As the rate of change of the current in a coil changes, the magnetically induced voltage generated is also proportional to the same change. This varying voltage is then further processed into usable electricity.

By taking advantage of its efficient magnetic shielding and efficient winding techniques, the fixed inductor in the SCRH4D18-390 is able to maintain a constant inductance even when exposed to significant changes in temperature or changes in surrounding magnetic fields. This makes it suitable for use in a wide range of electronic applications, such as power distribution systems, communication networks, medical equipment and consumer electronics.

The SCRH4D18-390 is a fixed inductor that is well suited for exceptional electrical and mechanical performance. Its wide operating temperature range and high quality construction make it an ideal choice for any application requiring an efficient and reliable inductor. In addition, its small size and superior performance make it particularly useful for space-sensitive applications.
