Fixed inductors are electronic components that play an important role in the construction of electrical circuits. They have the function of storing energy with magnetic field induction, and act as filters, signalgrounded circuits, or as a carrier signal generator. SP1812R-224K is a fixed inductor produced by Sumida, and it has multiple usages in the electronic circuit.

This part features a 2.2µH inductance with 1.5A maximum current, and a tolerance rate of ±20%. It has a good power loss in its performance channels and an operable temperature range from -40 to +125℃. The DC resistance is 33mΩ, with an SRF of 23MHz, and a maximum DC resistance of 46mΩ. This part is suitable for application in high-frequency communication circuits and other telecommunication circuits such as oscillators, amplifiers, filters, radio receivers, and sound amplifying devices.

The working principle of the SP1812R-224K is simple. It consists of a coil and a core encased in its shell. The core is mainly made of silicon steel with a high permeability, which is essential for energetic induction. When a direct current is passed through the coil, it produces a magnetic field that is linked with the core to create inductance with the electromotive force. The strength of the magnetic field is proportional to the current and the number of coils.

In addition, the SP1812R-224K can reject any interference from high-frequency signals, allowing for efficient operation in high-frequency circuits. With a low minimum set inductance, it can also cover a wide range of its operating frequency. As far as the shape of the inductor is concerned, this part is generally square and thin, perfect for cable winding.

The SP1812R-224K is not only economical in its production costs but also easy to operate. It has high permeability and low resistance to electric current, which enables it to perform well in its applications. It can reduce the temperature rise of electronic components and amplify signal and power effects, thus ensuring a good signal-noise ratio.

All in all, the Sumida SP1812R-224K fixed inductor is an ideal choice for high-frequency communication and telecommunication circuits. Its easy access to the market and its user friendly characteristics allowed users to easily incorporate it in their projects. With its high inductance and low DC resistance, it can provide a stable power output in most application fields.
