Fixed inductors are electrical components used to store and discharge energy between the two circuit components. They are mainly used in power supplies, various filters, amplifiers, frequency dividers, oscillators, and waveform detectors. 1638R-28H is one type of fixed inductor used for long and short-time pulse current applications. This article is focus on 1638R-28H application field and working principle.

The most important aspect of an inductor is its inductance, which depends on the central core, the geometry and size of the winding, and the number of turns of the wire used in its manufacture. The 1638R-28H fixed inductor is built from wire wound in the form of a rectangular disk, known as planar winding technology. It has a wide operating temperature range between -55℃ and +110℃ and the inductance range is from 5.2µH to 15µH with tight tolerances as low as ±1%. Its rated current from 0.17A to 0.27A with a saturation current of 0.29A. Moreover, the maximum DC resistance is 0.48 ohms that provides excellent signal integrity.

The 1638R-28H fixed inductor has been widely used in the application fields such as automotive, cellular phones, digital cameras, digital TVs and other consumer electronics. It will be used in power supplies, MOSFETs, IGBTs and other electronic components to regulate the energy storage and release. Besides, it can also be used as an anti-feedback choke in driver circuits as well as in RF circuits. Furthermore, it can be used as load inductor in high power switching supplies. The incorporation of ceramic material provides excellent thermal characteristics that allow it to be used in power supplies and other heat sensitive applications.

The working principle of 1638R-28H fixed inductor is based on the law of induction. When an electrical current flows through the inductor coil, an electromagnetic field is created from the winding. This electromagnetic field is in opposition to any change in the AC current flow, causing induction. This principle works as a form of trapped energy storage and works by releasing the flux to the surrounding circuit whenever a change in current occurs.

The 1638R-28H fixed inductor is a high-performance component ideal for use in automotive electrical systems. Not only can it provide excellent circuit performance, it can also withstand high temperature environments. Its small size and light weight makes it easy to fit in small spaces, making it an ideal choice for applications such as power supplies, MOSFETs and IGBTs. This inductor can help to reduce ripple noise due to its low DC resistance and excellent signal integrity. Therefore, the 1638R-28H fixed inductor is a perfect choice for automotive, consumer electronics and other high temperature applications.
