Fixed inductors are electronic components used for a wide range of purposes, such as load balancing, coupling signals, filtering signals or inductive load, etc. One of the fixed inductors is the SD53-680-R, which is used for common power supply applications.

The SD53-680-R is a large shielded 360μH ferrite core inductor with a lead-free finish. It has two connections, pin hole and PCB slot (through hole), and an insulated epoxy case. It meets all US and European environmental standards such as lead free, RoHS, Pb-free and EU-REACH.

In terms of structure, the SD53-680-R consists of toroidal cores, the cores are filled with magnetic microwire, high temperature resin insulation, and high temperature resistant paint used for exterior protection. The shield layer on the outside can reduce interference from external radiation and reduce magnetic leakage.

The application fields of the SD53-680-R are diverse, such as uninterruptible power supply, inverter, motor controller, line filter, etc. It serves as a current limiter in the circuit, connecting the power supply and the load to ensure the safe and normal operation of the entire power circuit. With high inductance, low loss, and high current, the SD53-680-R can also be used in some driver circuits that require high-power output, preserving the current output and frequency stability.

The SD53-680-R also has a wide range of working principles. The main working principle is that when the current passes through the ferrite core of the inductor, a magnetic field is generated in the energy storage layer. The resulting magnetic field can resist changes in the current flow, but the energy can be stored in the magnetic field of the inductor itself. When the current stops or decreases, the energy that has been stored in the magnetic field is released by the inductor to maintain a certain current flow.

In a nutshell, the SD53-680-R is a type of fixed inductor mainly used in power supply applications, with a wide range of application fields and diverse working principles. It has many features such as high inductance, low loss, high current, high temperature resistance, insulated epoxy case and shielding layer, designed to meet various high-power output requirements and to ensure the safe and normal operation of the circuit.
