Fixed inductors, also referred to as “code inductors”, are printed circuit board-level (PCB) components used in a wide variety of electronic circuits. They are more commonly used in radio frequency (RF) and power applications where inductance values need to remain constant over a wide frequency range. The SDR0805-392KL is one of the many fixed inductors available and is designed for applications such as power supplies, power amplifiers, and power converters.

The SDR0805-392KL is a relatively small-sized component, making it ideal for portable applications where space is at a premium. It features a toroidal core and is designed to provide a low DCR (DC resistance) and a high inductance value, making it particularly suitable for high-frequency power conversion applications.

In terms of the working principle for the SDR0805-392KL, it relies on the principle of Faraday’s Law of induction. This law states that a changing magnetic field will induce a current in a conductor, such as a coil or winding. This induced current is known as an “induced EMF” and is used to create an inductance value. The SDR0805-392KL uses this induced EMF to create an inductance value of 3.92mH.

The SDR0805-392KL also features a low ESR (equivalent series resistance). This is important in power-conversion applications, as a low ESR value allows for better power conversion efficiency and a more consistent current. Additionally, the low ESR value of the SDR0805-392KL helps to reduce the risk of power-supply noise and reduces the distortion of the current waveform.

The SDR0805-392KL is also designed to be tolerant to varying line voltages and operating temperatures, making it suitable for many applications including RF and power conversion applications. Furthermore, it is capable of handling a high peak current, making it suitable for high-frequency power amplifiers.

The SDR0805-392KL is commonly used in automotive, industrial, communications and consumer applications. It is also used in circuits that require an inductor to provide buffering or to provide filtering for AC or DC waveforms. Furthermore, it can also be used for impedance matching and for providing high-current gain for power conversion applications.

In conclusion, the SDR0805-392KL is a common fixed inductor that is suitable for a wide range of applications, thanks to its low DCR, high inductance value, low ESR, and tolerance for a wide range of operating environments. It is capable of handling high peak currents, making it suitable for high-frequency power amplification, RF and power conversion applications.
