Fixed inductors are electrical components used for many applications, such as electromagnetic interference (EMI) attenuation and filtering, energy storage, harmonic generation, and voltage regulation. The SRR1240-121K is a fixed inductor designed for applications in switching power supplies and other high power switching applications.

The SRR1240-121K is designed to provide high power performance in an extremely compact size. With a design that utilizes an advanced winding technology, the SRR1240-121K minimizes the current and voltage ripple for high efficiency performance. The construction of this inductor features a self-shielded core and a case which significantly improves magnetic shielding, resulting in a high current, low noise power supply.

The SRR1240-121K utilizes a drum core, alternatively known as a toroidal core, consisting of one or more circular disks. This type of core provides excellent magnetic properties while minimizing the physical size of the inductor. The core material is customizable, allowing designers to create unique magnetic properties tailored to the specific application. Similarly, the winding can be customized to provide the desired inductance and current-handling capabilities.

From a working principle standpoint, a fixed inductor is a passive component, meaning it does not require a power source of its own in order to operate. The core material stores energy in the form of a magnetic field, which is then released when the current through the inductor diminishes. This structure creates a magnetic flux that induces a current between the inductor’s two electrical nodes. The magnitude of this current is dependent on the magnetic characteristics of the core material, the number of windings, and the applied voltage.

The SRR1240-121K is a fixed inductor intended for application in a variety of switching power supplies, including those with redundant power supplies and high power loads. This inductor is optimized for excellent noise suppression, high efficiency, and long-term stability. With a wide temperature range and high temperature rating, it is an ideal choice for demanding electronic system design.

Moreover, this fixed inductor features an improved shielding configuration that reduces commonmode inductance and noise, allowing for superior signal integrity and EMI/RFI suppression. The SRR1240-121K also features an overcurrent limitation and an enhanced thermal design for improved safety and reliability.

In summary, the SRR1240-121K is a fixed inductor designed for applications in high power switching applications, such as power supplies and redundant systems. With its advanced winding and core design, the SRR1240-121K provides excellent power performance, EMI/RFI suppression, noise reduction, high efficiency, and long-term stability. This inductor is an excellent choice for any high power system design.
