Fixed inductors are components used in electronic circuits to store electrical energy in a magnetic field. They are used in a wide variety of applications, including radio frequency signal filtering, voltage smoothing, power supply and DC-DC conversion, and pulse-width modulation. The SP1812R-122K is a fixed inductor from Samsung that is used in a variety of applications.
The SP1812R-122K is a general purpose, through-hole mounted, RF Filtering Inductor. It has a maximum impedance of 8.7 ohms at its resonant frequency of 2.4MHZ. It is designed to provide high Q and low resistive losses at frequencies up to 8GHz. The inductance value of the SP1812R-122K is 12.2nH. The inductor has a low profile of just 0.74mm. It has a current rating of 0.52A and an operating temperature range of -40°C to +125°C.
The SP1812R-122K is widely used in telecommunication equipment,consumer electronics, medical equipment, automotive applications, and LED lighting.
The working principle behind the SP1812R-122K is fairly simple. Inside the inductor is a coil of wire. When current passes through this coil of wire, it induces a magnetic field around the coil. This magnetic field is what stores the electrical energy. The current that is passing through the coil must create a magnetic field of sufficient strength to store the required amount of electrical energy. If the current is too weak, then the inductor will not be able to store the required amount of energy.
The SP1812R-122K is designed to have a low DCR. This means that the resistance of the wire coil in the inductor is low, so that more current will be able to pass through it. This allows for the inductor to store more electrical energy, and is why it is able to offer high Q values.
The SP1812R-122K is an ideal component for applications that require Filtering, EMI/RFI suppression, and high impedance values at high frequencies. Its low profile and high current rating make it suitable for space restricted applications. The operating temperature range of the SP1812R-122K also makes it ideal for use in extreme temperature environments.
