Fixed inductors are passive components used for filtering capacitors and decoupling noise. They are composed of a coil and a core, which can play a role in providing AC current and forming a magnetic field. The SD3812-680-R is a fixed inductor made from ceramic. This product is designed to be a good choice for high-frequency switching power supplies and also provides good EMI suppression.

The SD3812-680-R has a high Q value of 290 and a high SRF of 21.2 GHz， allowing it to perform even in harsh environments such as high temperatures and high frequencies. Moreover, due to its small size and low weight, the SD3812-680-R is suitable for space-constrained applications. The inductance is measured in nanohenries (nH) and is between 0.154-0.180nH. The rated temperature range is between -40 to 125°C and can achieve very low DCR values, between 28-37mohm.

The working principle of the SD3812-680-R is simple. It consists of two coils wound on a ferrite core which is then encapsulated in a molded shell for environmental protection. When an alternating current flows through one of the coils, the core creates a magnetic flux that interacts with the other coil inducing an alternating voltage. This voltage is equal in magnitude but opposed in phase to the applied voltage, thus providing a resistance to the flow of AC. This process is known as electromagnetic induction.

The SD3812-680-R is usually used in noise-suppression circuits, voltage-stabilizing circuits, and other analog components. They are also used as part of a choke-balancing circuitry, which is used to reduce the amount of noise on a line. It can also be used in radios and telephones as an antennal coil for inductively coupling to a distant station. Finally, the SD3812-680-R is also a great choice for RF applications ranging from small communication devices to large industrial equipment.

Overall, the SD3812-680-R is an outstanding choice for fixed inductors due to its wide range of applications, high Q value, and its various features such as small size and low weight. Its high SRF makes it suitable for harsh environments as well, making it an excellent choice for signal filtering and power-supply applications.
