Fixed Inductors

Inductors are one of the fundamental types of electrical components. They consist of a wire or coil of wire wrapped around a cylindrical core, and are employed in a wide range of applications. The ELL-8UV4R7N is a wire wound fixed inductor, with a core material of ferrite. It has an inductance of 4.7 uH, a maximum current of 1.5 A, a self-resonant frequency of 3.7 MHz, a Q value of 100, and a temperature coefficient of +/- 1.5 % in a range of 20 to 80 celsius.

The ELL-8UV4R7N is used in a variety of applications, such as radio frequency circuits, local oscillator circuits, power supply filtering, and measuring circuits. It is also used as a DC blocking filter circuit, for applications such as television and audio equipment.

In a radio frequency circuit, the ELL-8UV4R7N is used as a band-pass filter. A band-pass filter is a device that passes a range of frequencies and rejects frequencies outside of the range. The inductor is used to block frequencies outside of the desired range. It is also used to reduce the direct current from the source.

In local oscillator circuits, the inductor is used to set the attenuation and frequency characteristics of the circuit. It is used to adjust the amplitude or frequency of the signal. It is also employed as part of a resonance circuit, where low-frequency signals are passed through the inductor and help to shape the signal\'s frequency response.

In power supply filtering, the ELL-8UV4R7N is used to filter out noise in the power supply, and to reduce the RMS voltage ripple that can cause interference. The inductor is also used in measuring circuits, where it is used to measure voltage or current.

The ELL-8UV4R7N has an internal resistance of 0.20 ohm, which is relatively high for an inductor. This is due to the wire wound construction of the component. The resistance is important, as it determines the power dissipation of the inductor. At higher frequencies, the inductor will dissipate more power due to the increased effective resistance.

The other important factor to consider is the inductance of the component. The ELL-8UV4R7N is designed to be a low-inductance component, as its inductance is only 4.7 uH. This is important, as high-value inductors are more prone to noise and interference. Low-inductance components are more stable, as the inductance remains constant over a wide frequency range.

The ELL-8UV4R7N is a robust and reliable component, and has a number of advantages over other types of inductors. It has low resistance, high inductance, and is relatively immune to noise and interference. Its wide range of applications makes it a popular choice for a variety of projects.
