Inductors are electronic components used mainly in signal processing and communications, where they serve as a filter for the power supply, provide an electromagnetic shield for electronic circuits, and couple circuits together. Fixed inductors, unlike variable inductors, have a set inductance, usually measured in micro-henries (μH). One such type of fixed inductor is the SL1923-681K1R3-PF, an air-core, axial-leaded, molded device with an inductance of 680-μH.

Application Field

The SL1923-681K1R3-PF is generally used in high frequency applications, such as radio frequency (RF) circuits and antenna systems. Its narrow inductance range makes it suitable for use in multiplexers, filters, and impedance matching devices. This inductor also offers stability with temperature variations, making it ideal for use in temperature-sensitive circuits.

Working Principle

Fixed inductors work by storing electrical energy in a magnetic field. When current passes through the inductor, a magnetic field is created, which induces a voltage. This voltage is proportional to the rate of change of the current passing through it. The SL1923-681K1R3-PF has a relatively high resistance, meaning it has low power dissipation, making it suitable for use in high-frequency applications. The inductor also has a comparatively high quality factor, meaning it has better inductive reactance at higher frequencies, making it ideal for use in RF circuits.

Overall, the SL1923-681K1R3-PF is a versatile fixed inductor, capable of performing at various frequencies and highly resistant to temperature variations. It is primarily used in high-frequency applications, such as RF circuits and antenna systems, to filter power, provide an electromagnetic shield, and couple circuits together. This inductor has a relatively high quality factor, making it ideal for use in RF circuits.
