Fixed inductors are currents transformers with an inductance that is not expected to adjust. These inductors are used in a wide range of applications, including voltage clamping, invertor and filter circuits, DC to DC converters, tuned circuits, and signal conditioning circuits. One of the most widely used fixed inductors is the SDS850R-105M. This article will discuss its application field and working principle.

The SDS850R-105M model is a passive component of high frequency power, designed for switching power supply applications in the consumer electronics markets. This model is an inductor with increased power capability supplied in a SEPIC configuration, optimizing the current density in the winding and reducing power dissipation. These inductors can work for switching frequencies up to 250kHz, making it one of the most widely used inductors on the market.

In terms of applications, the SDS850R-105M model is suitable for use in AC/DC and DC/DC converters, because its high current capability allows for wider duty cycles achieved in high power LED drivers. Switching power supply designs require high-frequency inductors to support the high current and torque requirements of the switching transistor. This inductor is suitable for these applications as its high inductance and excellent current handling properties are able to guarantee a greater transformer action. In addition, the SDS850R-105M inductor is also suitable as current-sensing components in application such as motor control, in inverter and resonant circuits. The construction of this type of inductor also makes it suitable for PFC converters with its high rated current and low DCR.

The working principle of the SDS850R-105M is based on the basic magnetic effects of an inductor. This inductor converts the direct current of the main power input into a alternating current in the secondary winding, which is generated due to the mutual induction between the primary and secondary windings. The alternating current created in the secondary winding can also be used to power a load, depending on the design of the circuit.

In summary, the SDS850R-105M is a highly versatile fixed inductor suitable for use in a variety of applications. Its high current capability and ability to handle high frequencies means that it is a popular choice for switching power supply designs. The working principle employed by this inductor is based on the same basic principles of inductive components as other inductors on the market.
