Fixed inductors, including 9405-30 are widely used in consumer electronics, as they provide the circuit with a fixed amount of inductance. Fixed inductors can be either in the form of an air coil, a wound ferrite-core coil, or a wound nanocrystalline core coil. Generally, air core or ferrite cores are more suitable for lower power applications, such as the audio applications, while nanocrystalline cores are mostly used in larger power applications, such as motor drives.

The 9405-30 is a surface-mounted nanocrystalline, high-current, widely used inductor. It is especially designed to deal with the high frequency characteristics, like many oscillatory waveforms. The inductance value of 9405-30 is fixed and ranges from 0.1uH to 1mH. It is available in both axial and radial leads.

It comprises multiple layers of ultra-fine nanocrystalline cores which are wound together and vacuum-deposited in an air gap between two electrically conductive copper layers. This makes it possible to provide extremely high inductive current, compared to traditional inductors, due to the reduction of distributed inductance losses. This also helps to reduce losses in high frequency operations. When it comes to determining the exact value of the inductance, it depends on the amount of turns, the core material, and the core thickness.

In its working principle, the 9405-30\'s current carrying conductors take up the shape of a standing waveform, and thus, helps reduce the Skin Effect. Skin Effect is the tendency of the moving electrons to settle on the outer layers of the conductor while avoiding the internal portions. This discrepancy is caused due to the increase of the frequency. As the frequency increases, the electromagnetic field around the conductor also increases. This makes it difficult for the electrons to move freely within the conductor. By taking up the shape of a standing waveform, the 9405-30 reduces overall Skin Effect losses.

The 9405-30 is also quite phase-stable. Its phase stability helps the inductor maintain its inductance through a wide variety of temperatures. This further helps reduce energy losses, as an inductor that isn\'t phase-stable experiences a considerable amount losses in shifting temperatures.

The 9405-30 inductor is also largely used in amplifiers, in motor control applications, and in power converters. which require reliable, fixed inductance. The robust structure of the 9405-30 makes it ideal for high-temperature environments, with a maximum working temperature of +125°C. Furthermore, it also features high saturation and low DCR (DC Resistance).

The 9405-30 is a perfect choice for applications when fixed inductance is required with high current capabilities and excellent phase stability and phase-timing accuracy. It can also be used for all kinds of high frequency power applications like SMPS circuits, power converters, inverters, etc., thanks to its unique winding design and robust construction. It is thus, one of the widely used inductors in power electronics.
