Fixed Inductors: CDR156NP-471LC Applications and Working PrincipleInductors are an important component used in a wide variety of applications including power supplies and electronic circuits. A fixed inductor is an inductor with static magnetic properties that are determined by its physical characteristics and are insensitive to external magnetic fields. CDR156NP-471LC is a type of fixed inductor designed for high performance applications with low profile, small volume and light weight. This fixed inductor is a cut tape provider of surface mount type that offers extensive product and fast delivery. It is manufactured using advanced technology and consists of two cores made of ferrite material with a copper wire and epoxy resin soldered on either end. It has a standard tolerance of ±20%. The CDR156NP-471LC is particularly suitable for cellular projects, TV set-top boxes, digital cameras, optical drives and other low-profile applications. As the name suggests, the working principle of the CDR156NP-471LC fixed inductor is based on the principles of electromagnetic induction. When a conductor moves within a magnetic field, a voltage or electromotive force (emf) is induced in the conductor. Similarly, when an alternating current passes through the windings of an inductor, a magnetic field is produced which, in turn, induces an emf in the windings of the inductor. Thus, the opposing action of the field and the emf produces a self-induction effect that restricts the amount of current passing through the inductor. The CDR156NP-471LC fixed inductor has a high self-inductance which makes it ideal for applications such as switching power supplies that require fast switching, and for AC circuits such as radio frequency (RF) circuits. It also has low DC resistance which enables it to operate efficiently at higher frequencies while maintaining low power dissipation. The inductance of the fixed inductor is directly proportional to its dimensions and the number of turns of the coil. Thus, in order to achieve higher inductance values, the dimensions of the coil and the winding have to be increased, resulting in increased power consumption. The CDR156NP-471LC fixed inductor is designed for high efficiency and low profile applications that require lower power dissipation. It is capable of providing high inductance values with low DC resistance and is suitable for use in switching power supplies and AC circuits. Moreover, its small size makes it ideal for space constrained applications.
