Fixed inductors have traditional applications in power supplies, filters and communications, and are used as part of other component parts. However, with the rapid development in electronic technology, designers’ requirements for inductors are getting higher and higher. A core part of this is its external size and power dissipation. The SP1008-183G inductor is an ideal solution for this task.

The SP1008-183G inductors are designed to provide a high power density balance for improved performance in any application. This inductor boasts an extremely low DCR of 0.050 ohm and an ultra narrow footprint of 0.8mm x 0.8mm. It has a high saturation current of up to 15A, and a rated frequency of up to 30 kHz and can be used in a wide range of applications. With its ability to reduce EMI and withstand power disturbances, the SP1008-183G inductor is the perfect choice for any designer looking to maximize performance.

Working Principle

Fixed inductors use the principle of electromagnetic induction. An electromagnetic field will be generated when a conductor is subjected to an alternating current/voltage. This field is composed of two solenoid coils wound on a core. The solenoid coils will generate a circulating current in the core, inducing the electromotive force, and the magnetic energy received will be stored in the core.

The SP1008-183G inductor uses this same principle of electromagnetic induction. It is composed of two wire-wound inductors, one wound in a clockwise direction and one in a counter-clockwise direction. When these two inductors are subjected to an alternating current, an electromagnetic field is created between them. This field causes the electrons in the conductors to move in a circular motion, creating a circulating electrical current in the core. This electrical current then produces a magnetic field, which stores the energy obtained from the external electrical current.

Applications

The SP1008-183G inductors are ideal for high-power saving and high-efficiency applications. Their tiny size and extremely low DCR allow them to be used in space-restricted settings, such as mobile phones and other handheld devices. Additionally, their high saturation current and wide-frequency range make them a great choice for high-efficiency motor drives, DC/DC converters, switch-mode power supplies, and current-mode control circuits.

Other applications include RFID tags, digital cameras, networking equipment, and other battery-powered applications. With its high power density and reliability, the SP1008-183G inductor is an ideal solution for any application that needs to maximize efficiency while meeting space requirements.

Conclusion

The SP1008-183G fixed inductor is an essential component for any modern electronic device. With its tiny footprint, ultra-low DCR, wide frequency range, and high saturation current, it is the perfect choice for high-efficiency motors, switches, and power supplies. Its ability to reduce EMI and withstand power disturbances makes it ideal for any application that needs to maximize performance while taking up the least amount of space possible. It is easy to see why the SP1008-183G inductor is the preferred choice for designers of any level.
