The 4494-686 is a type of fixed inductor designed for high-performance switching applications. This article will explain the application field and working principle of the 4494-686 Inductor.

Applications of the 4494-686

The 4494-686 Inductor from KEMET is designed for high frequency switching applications, especially where very low DC bias currents are required. It is widely used in telecommunications, network infrastructure, instrumentation, consumer electronics, and automotive industries. The 4494-686 can also be found in energy-harvesting applications, high-density switching power supplies, and wireless modules.

The 4494-686 performs analog circuit functions, such as signal filtering and smoothing. It is also used for low-loss AC line termination and provides identical performance for both high-frequency and low-frequency applications. It is especially suitable for power conversion and small signal power transfer applications.

Working Principle of 4494-686

The 4494-686 Inductor from KEMET is a fixed inductor with an inductance of 1.6mH. It has an impedance of 0.2Ω and a SRF of 133MHz. It is a surface mount (SMT) device and its size is 16.2mm × 11.2mm × 4.7mm. The 4494-686 is constructed from high-efficiency alloy core material with an E-grade insulation system.

The 4494-686 works by providing a magnetic field in the air gap which induces a counter EMF in the inductance windings. This EMF reduces or opposes the current flow through the inductor, thus resulting in a decrease in the total voltage drop. The 4494-686 is designed to provide high frequency performance without significant losses. The device also offers low profile and superior temperature characteristics.
