Fixed inductors are a type of inductor that doesn\'t require any tuning adjustments. The most common fixed inductor type is the air core type, which consists of a simply coil of wire. The air core type has no core material, so it has limited inductance when compared to the other types, but it is favored due to the ease of installation and high accuracy. The SWS-1.20-38 is a type of high performance fixed inductor.

The SWS-1.20-38 is a high-frequency application inductor specifically designed to be used in the audio frequency range and is suitable for use in RFID readers, Wi-Fi receivers, cell phone antenna systems, and audio power amplifiers. This inductor features a very stable core material, allowing it to maintain its inductance over a wide temperature range and providing excellent RFI shielding. It has a three-layer ferrite-cored construction which allows it to provide high inductance and current handling capabilities while maintaining a low DC resistance.

The SWS-1.20-38 is constructed with a magnetic core and a copper windings winding around it. The core material is a unique combination of iron oxide, steel, and chrome, giving it a high thermal conductivity and a very low DC resistance. This allows it to provide higher inductance levels for a given current level than other types of fixed inductors. The winding wire is silver plated, making it resistant to corrosion and providing superior performance at higher frequencies. The SWS-1.20-38 also features a non-conductive coaxial design, providing excellent shielding for the inductor.

The primary application for the SWS-1.20-38 is to provide a stabilized voltage output in audio power amplifiers. Its pricing and high performance make it ideal for stereo and mono power amplifiers. It is also used in high-frequency applications such as RFID readers, Wi-Fi receivers, and cell phone antenna systems. Its non-conductive design makes it particularly well suited for use in high-performance audio power amplifiers, as it can be mounted directly to a printed circuit board without the need for extra shielding material.

The working principle of the SWS-1.20-38 is simple. It operates on the same principle as an air core inductor, only it has the advantage of its core material. When the current passing through the winding wire is changed, the magnetic field in the core material changes accordingly. This causes a delay in the current flow, causing the voltage output of the inductor to remain constant even as the current passes through it. This stability makes the SWS-1.20-38 a suitable component for use in audio power amplifiers, as it will keep the voltage output stable even when large changes in current occur.

The SWS-1.20-38 is a high-performance fixed inductor that offers excellent RFI shielding, a wide temperature range, and high frequency applications. Its non-conductive design makes it ideal for use in high-performance audio power amplifiers, RFID readers, Wi-Fi receivers, and cell phone antenna systems. With its superior performance and long-term reliability, the SWS-1.20-38 is a cost-effective solution for any audio power amplifier application.
