Fixed Inductors

Fixed inductors are widely used in many electronic devices, including those used for power supplies, telecommunications, audio, lighting, and computers. They play an important role in both radio frequency and low-frequency applications. The 3094R-683HS is a common type of fixed inductor used for many applications. This article will discuss its application fields and working principles.

Application Fields

The 3094R-683HS fixed inductor is a high quality device that can be used in a variety of electronic applications. Its applications include power supplies, instrumentation, robotics, and audio and video equipment. It is also used in power filtering, which is important to ensure that the resulting output is free from electromagnetic interference. This inductor is capable of providing low DC resistance and high current carrying capacity, making it the ideal choice for these applications.

The 3094R-683HS is specifically designed to be used in high frequency circuits, as it offers the highest frequency performance among the inductors. With its exceptional efficiency, the 3094R-683HS is an ideal choice for high power switching and micro controllers, where high switching powers are required with minimal power losses. It is also suitable for automotive and industrial applications, thanks to its low electromagnetic interference and its wide temperature range.

Working Principles

A fixed inductor can be characterized by three basic parameters: inductance, DC resistance and quality factor (Q). All these parameters depend heavily on the shape and size of the coil. The 3094R-683HS fixed inductor falls into the category of distributed inductors, which is characterized by its rectangular shape. This shape creates higher self-resonance frequencies than a round-shaped inductor. The 3094R-683HS also features high Q values and is capable to reach low DC resistance values even at high frequencies. As a result, the device exhibits extremely low losses and can handle high currents at frequencies up to 200MHz.

The 3094R-683HS fixed inductor works by producing an inductance through the winding of its coils. When electricity passes through the inductor, the current and voltage vary with respect to time, often referred to as electrical reactance. This reactance is determined by the inductance, the inductor’s size and the shape of its coils. The inductance in the 3094R-683HS is determined by its DC resistance, meaning that as the DC resistance increases, the inductance decreases. This makes it suitable for high frequency applications where small inductance is required to ensure a low DC resistance.

Conclusion

The 3094R-683HS fixed inductor is a device specifically designed to provide high current carrying capacity, low DC resistance, and exceptional frequency performance. Its rectangular shape results in a higher self-resonance frequency than a round-shaped inductor, making it suitable for high frequency applications. It is also capable of providing low losses and producing a low DC resistance even at high frequencies. With these characteristics, the 3094R-683HS is an ideal choice for power supplies, instrumentation, robotics, and audio and video equipment.
