Fixed Inductors

A fixed inductor is an electronic circuit component whose job is to store energy in the form of a magnetic field. An inductor is basically a coil of wire through which electric current is passed. The amount of current passing through the coil creates a magnetic field around it that stores the energy. The nature of this magnetic field is such that it resists changes in the current, creating inductance. This inductance opposes any change in the current and can be measured in henries (H).

The ELC-15E681 is one such fixed inductor and it is used in a range of circuitry applications, most notably RF transmitters and receivers, and digital signal processing. It offers a wide operating temperature range of -55°C to +125°C, making it ideal for use in extreme conditions and in digital applications that require high accuracy.

This fixed inductor has a low inductance value of 3.3µH and with its low winding resistance of 0.039Ω, it is able to achieve high efficiency in the many different electrical applications that require it. In addition, the ELC-15E681 has a high self resonant frequency of up to 50MHz, ensuring that it can respond accurately and effectively even when operating at high frequencies.

So, how does the ELC-15E681 fixed inductor actually work? The basic principle of its operation is to store and release the electrical energy Within the coil. When current flows through the inductor, this current forming a magnetic field around it. This essentially stores the electrical energy, which can then be released on demand. By adjusting the current, the output current can be increased or decreased, depending on the needs of the application.

In addition, the fixed inductor also works by providing some resistance to current changes, as mentioned above. Through this process, electrical noise, which is caused by rapid current fluctuations, can be greatly reduced or eliminated. This is obviously beneficial in applications that require precise control and accurate operation.

In summary, the ELC-15E681 fixed inductor is highly versatile, offering a range of applications in digital and RF technologies. Its low inductance value, high operating temperature range, and high self resonant frequency make it ideal for controlling current in applications that require accurate response and output. Moreover, its ability to reduce electrical noise makes it suitable for use in noise-sensitive circuits.
