Fixed InductorsFixed inductors are electronic components used as filters to prevent high-frequency signals. Commonly used in power supplies, they also serve a variety of applications including voltage regulation, power conversion, multi-stage amplifiers, and voltage regulation. The inductance of an inductor can be adjusted to a predetermined level, specified by a given value or the manufacturer.The SCR74B-820 is a fixed inductor that has a wide range of uses. It is particularly suitable for applications where a low ripple current is necessary in a low-voltage AC/DC power supply, or in circuits with high frequency commutations. This inductor has a round cylindrical shape and is made of a lightweight, surface-mountable, non-absorbent material.Working PrincipleThe SCR74B-820 operates on an alternating current, which is generated by an external source. When this alternating current is applied, the inductor’s wound atomic structure generates a magnetic field, resulting in a counter EMF that opposes the original frequencies. The inductance of the inductor is then affected by both the initial frequency and the magnitude of the counter EMF.The inductance of the SCR74B-820 is adjustable by adjusting the number of turns on the windings and varying the winding cross-sectional area of the inductor. The angular frequency of the applied current also affects the inductance of the fixed inductor, as changes in frequency result in a variation of the amount of energy stored in the inductor. The inductance of the inductor will also vary with the delivery of direct current, as direct current tends to cause hysteresis effects in the inductor, resulting in decreased inductance.The SCR74B-820 is also equipped with a number of features that make it suitable for a variety of applications. Its small dimensions and low profile make it ideal for use in space-constrained environments. Its low power consumption ensures it is economical and efficient. The inductor is also highly reliable and durable, guaranteeing long-term operation even in harsh and uncomfortable conditions.The SCR74B-820 is an ideal choice for those looking for an economical solution for their power circuit needs. With its removable core, the inductor can be used in a wide variety of applications, from power conversion and voltage regulation to multi-stage amplifiers. Its adjustable inductance makes it extremely versatile and able to meet the needs of most applications. The inductor is also extremely reliable and durable, ensuring it will perform over long periods of time in even the most challenging and adverse conditions.
