Fixed inductors are electronic components that largely consist of a wire-wound or etched coil. They are used in applications such as filtering, tuning, coupling and sensing. The SPD127-154M inductors are a Fixed Inductors type of component and they have a dedicated application field and a specific working principle. The SPD127-154M inductor is a component commonly used in power line and power system applications. It is suitable for a range of AC/DC power applications as high a 125W, with typical nominal inductance values up to 154nH. Its maximum DCR typically remains below 0.06Ω. Additionally, the component features an all-plastic compact design for high mechanical stability and long-term reliable service. Finally, its excellent temperature characteristics, up to 150ºC, guarantee compatibility with diverse environments, particularly for high ambient temperatures.The structure and principle of the SPD127-154M Fixed Inductors can be simplified as follows: Inside the SPD127-154M component, a two-layered, flat-sided core is wrapped with high-quality magnetic wire. The core is made of materials that exhibit properties like high saturation flux density, low coercivity, and high permeability, allowing for a high packing factor and maximum magnetic saturation. This high level of saturation results in a refined selection of inductance values. The component of the coil assembly is built with these two layers which can be seen as two windings arranged in series.The number of turns and the round-shaped construction of each are designed to attain optimal results. The arrangement of turns works as a shield of magnetic flux that provides a low profile inductance core.The SPD127-154M inductor also offers good performance with regards to frequency characteristics. This component has an anti-corrosive epoxy encasing for the core and copper solder tabs that join the conductive parts. The good frequency characteristics of the SPD127-154M derive from the flat shape of the core, which facilitates low leakage generation, resulting in a low impedance loss. As a result, the SPD127-154M exhibits high impedance and low losses in all frequency regions, making it suitable for both low-frequency and high-frequency circuits.The SPD127-154M also has excellent common mode noise suppression abilities. This is accomplished through the core’s magnetic properties – unlike other component inductors, the SPD127-154M can effectively suppress the generated noises of high-frequency EM and power wave circuits. This makes the SPD127-154M a powerful tool for power line filtering, where AC/DC noise suppression is essential.In conclusion, the SPD127-154M distributed Fixed Inductor has unique performance features and is especially suitable for power systems and applications. Its low DCR, excellent frequency characteristics, and low noise levels make it a widely used component design for many power systems. Its all-plastic compact construction materials also add usability for many different environments, ranging from low temperature to high temperature and harsh conditions.
