Fixed inductors are the most widely used type of inductor. The SP1812R-473H is a fixed inductor used in various applications, and this article outlines the unique features of the inductor and its various applications.

The SP1812R-473H is a low profile quad flat inductor with a 4.73mh inductance, which is ideal for RFID, portable RF, automotive, and industrial applications. It features an ultra-small size, a maximum current rating of 6A, an operating temperature range of -40C to 70C, and a maximum resistance of 0.032 ohms.

The SP1812R-473H is geared towards space-constrained applications, thanks to its ultra-small size. The inductor is constructed with nickel-plated copper terminals on one side and a SMD-type quad flat no lead (QFN) package on the other. The terminals are compatible with most fluxes, which makes the inductor suitable for high-temperature soldering processes.

The SP1812R-473H offers excellent noise suppression, thanks to its low-resistance design. It also has a low distributed capacitance that eliminates voltage spikes and helps reduce the amount of electromagnetic interference (EMI) in circuits. This makes the inductor a suitable choice for high-frequency applications, such as RFID systems and automotive systems.

The SP1812R-473H also offers excellent temperature stability, which is essential for automotive applications. It is also RoHS-compliant, making it a safe and reliable component for use in various applications. Moreover, the inductor is covered by a protective coating so that it can be used in harsh environments.

The working principle of the SP1812R-473H is simple. When electric current passes through the inductor core, it produces an opposing magnetic field. This opposing magnetic field stores the energy that passes through the inductor in the form of a magnetic field. The inductor stores the energy in the form of a magnetic field until the current that passes through the core reaches zero. This stored energy is then released back into the circuit.

The SP1812R-473H is a versatile inductor that can be used in a variety of applications. Its small size and high working temperature stability make it an ideal choice for portable, automotive, and industrial applications. Its low distributed capacitance makes it great for high-frequency applications, such as RFID systems. Furthermore, its protective coating makes it suitable for harsh environments, such as automotive and industrial applications.
