Fixed inductors are usually used in electrical and electronic circuits as part of the components to perform the function of storing and discharging energy. Among the various types of inductors, SDS850R-473M is an example of fixed inductors that has been widely used in many applications. Therefore, in this article, we will discuss about SDS850R-473M application field and working principle.SDS850R-473M belongs to the family of radial-lead molded inductors which are characterized by a long life design, high reliability and endurance. Its application field covers computer peripherals, home electronics, remote controls, consumer electronics, audio and video equipments, telecommunications, etc. Its working frequency range is from 0Hz to 1.5MHz and the wide working temperature range from -40 degree Celsius to +105 degree Celsius makes it suitable for many harsh environment applications. The basic working principle of SDS850R-473M is that when an AC current passes through its windings, a magnetic field is generated. This magnetic field blocks a part of the AC current, leading to a linear drop in the current which generates an opposing voltage. This voltage eventually becomes equal in magnitude to the driving voltage and the current drops to zero. This phenomenon is called ‘self-induction’ where the inductor works like an energy storage device. As the current changes, so does the magnetic field, thus producing an opposing voltage which counteracts the driving voltage. SDS850R-473M is designed to maintain a constant inductance level over its wide operating temperature range. The inductance is determined by the wire gauge, number of turns, the core material used, the shape and the type of core material used. The inductance level will remain constant as long as the ambient temperature does not change significantly. Its resistance to change in inductance over frequency is also improved by using a low loss magnetic core material.In addition, SDS850R-473M is characterized by a very low self heating effect thanks to the multi-layer windings and optimized winding layout. The entire construction of the inductor also helps to reduce EMI noise emission and further increase reliability. All in all, the features of SDS850R-473M meets the requirements of modern high performance applications.Overall, SDS850R-473M is a kind of fixed inductors that is widely used in many applications due to its long life design, high reliability and endurance. Its working principle of self-induction ensures that it works like an energy storage device. Moreover, it is resistant to change in inductance over frequency and is also characterized by a very low self heating effect and low EMI noise emission.
