Fixed inductors are a type of inductor, which have the tendency to resist the changes in the current flow with time, and are mostly used to store and transfer electrical energy. The LBC2518T1R0M is a particular model of fixed inductor used for capacitor−less applications in telecommunications equipment. It is used to support DC−DC converters, linecards, and other power applications. This type of inductor combines the advantages of low parasitic elements with the stability and the reliability of surface−mount components. This article will explore the application fields and the working principle of the LBC2518T1R0M.

The LBC2518T1R0M has a toroidal form factor, with dimensions ranging from 0.2” to 1.3”. It has an inductance range of 1.1 microhenries (uH), to 1.5uH, with a very low DC resistance of 0.50 mOhm. Its high frequency current saturation is 0.46, with a typical return loss insertion of 49 dB, making it the perfect choice for designing circuitry with low losses. It is also compatible with automated assembly environments, meaning that it is very easy and cost effective to use in production.

The main application field for this type of inductor is power applications that demand stability, reliability and efficiency, such as in equipment for data center and telecommunications systems. It has a high current sustain ability, an optimized thermal management and is resistant to outdoor environmental conditions, making it suitable for industrial use too. In addition, it offers excellent filtering reliability in most DC−DC conversion applications.

The working mechanism of the LBC2518T1R0M is based on the principles of electricity and magnetism. When a DC current is applied to its coil, a static magnetic field is generated, which induces an electrical current in the core of the inductor. This process is what prevents the DC flow from changing quickly, as it produces a magnetic field that opposes the applied current. Furthermore, when the applied current is stopped, the current in the inductor continues to flow, resulting in a lower inductance value.

This type of inductor also offers good high frequency transient performance, providing very clean power. It works by arresting the rate of change in the applied current, making it ideal for use with analog electronics in power circuits. As such, its design usually involves winding copper around a non−magnetic core, allowing for a very efficient energy storage and transfer. It also has very low electrical noise, making it suitable for high−speed data communication.

In conclusion, the LBC2518T1R0M can be used in various power supply applications, as it offers excellent stability, reliability, efficiency and thermal management. Its toroidal form factor makes it suitable for SMD assembly, while its optimized magnetic core and copper winding provide the required low−losses, high frequency transient performance, and low noise characteristics that make it so versatile. With its industrial grade build quality and wide range of application fields, this model is ideal for designers looking for a reliable and cost−sample fixed inductor.
