SWS-3.00-17

Fixed inductors are electrical components that are designed to provide an inductive effect in a circuit. SWS-3.00-17 is a specific type of fixed inductor manufactured by MAX WANG Corporation. SWS-3.00-17 is designed to have a low internal resistance and a high inductance (>3.00µH). This makes it well-suited for applications such as EMI suppression, decoupling, and energy storage.

The SWS-3.00-17 consists of a high-grade ferrite core, soft magnet alloy wires, and an epoxy coating. The core is shaped like a donut, with a hollow center and a high magnetic permeability. The wires are wrapped around the core in a specific arrangement according to the inductance requirement. The ferrite core and the winding arrangement determine the inductance, while the epoxy coating protects the components from moisture and dust.

When current passes through an inductor, it creates a magnetic field around it. This field induces a voltage in the inductor, which opposes the current flow. This phenomenon is known as “inductive reactance”, and it is the basis of how fixed inductors work.

When SWS-3.00-17 is used in a circuit, it acts as a common-mode filter. Common-mode signals, such as high-frequency interference, are absorbed and filtered by the inductor, reducing noise and potential damage to the circuit. Additionally, the inductor also provides a degree of low-pass or high-pass filtering depending on the inductance. This can be used to reduce noise, improve signal quality, or adjust signal bandwidth.

The SWS-3.00-17 is also useful in decoupling applications. Decoupling helps prevent “ground loops”, which can be especially troublesome in multilayer circuits. The inductor acts as a buffer between the circuit’s ground plane and the power line, thus preventing any voltage differences between the two. This prevents interference and ensures clean, reliable operation.

In summary, the SWS-3.00-17 fixed inductor is an easy and reliable way to incorporate inductive effects into a circuit. With its low internal resistance and high inductance, it is well-suited for applications such as EMI suppression, decoupling, and energy storage. It is also a cost-effective solution that is easy to incorporate into a design.
