Fixed Inductors are a type of electronic component that are used to store energy in the form of magnetic fields. They often function as components in RF circuits and are found in many different applications. The SRR1280A-390M is one such fixed inductor, and it is designed for use in power supplies, amplifiers, and various other electronic devices. In this article, we’ll take a closer look at the SRR1280A-390M, exploring its application field and working principle.

Applications

The SRR1280A-390M is a high-current, low-profile inductor that is designed to be used in a wide range of electronic applications. It features a low profile of just 0.35” (8.89mm) in height, making it suitable for use in limited-space applications. It also boasts an operating temperature range of -55°C to 125°C, ensuring reliable operation even in extreme environmental conditions. The SRR1280A-390M offers high-current densities, with a current rating up to 39.0a (TJ=25°C, L=15.8mH). As such, it is often used in high-current applications, such as switching power supplies and DC-DC converters.

In addition to power supplies and converters, the SRR1280A-390M is also suitable for use in various other electronic devices, such as power amplifiers, motor controllers, and industrial instrumentation. With its high-current and wide temperature range, it is an excellent choice for a range of applications.

Working Principle

The basic working principle of an inductor is simple: it stores electromagnetic energy in the form of a magnetic field. The way it works is that when current passes through the inductor, a magnetic field is created. This magnetic field, in turn, induces a voltage in the inductor. This induced voltage is known as the back-EMF (Induced Electromotive Force) of the inductor.

The SRR1280A-390M works in a similar way to other inductors. As current passes through the device, a small back-EMF is created, allowing it to store energy. This energy can then be released in the form of a “spike” when the current is cut off. This makes the SRR1280A-390M ideal for applications such as power supplies and converters, where fast transients are required.

Conclusion

The SRR1280A-390M is a high-current, low-profile fixed inductor that is used in a wide range of electronic applications. It is designed to offer high-current densities and an operating temperature range of -55°C to 125°C. Its basic working principle is quite simple, as it stores energy in the form of a magnetic field, allowing it to work as an energy source for fast transients. As such, it is an excellent choice for applications such as power supplies, amplifiers, and other electronic devices.
