Fixed inductors, also known as SMD inductors, are components used in electronic circuits to store energy in the form of a magnetic field. They are typically made from a coil of wire wrapped around a ferrite core, and are used in a variety of applications, such as filter circuits, electronic ballast and other power-sensitive applications. The ER1840-101JR is a fixed inductor produced by Taiyo Yuden that is a commercially available SMD device.

The ER1840-101JR is a relatively small, surface-mount type device designed for use in electronic circuits, and is typically available in a standard 0805 package size. It has a wide range of operating temperature, -40°C - +105°C, and has a maximum rated inductance of 1.5μH and a rated current of 1.3A. It features a ferrite core construction and a low DC resistance as well as low AC resistance, making it suitable for applications where low EMI is a requirement.

The working principle of the ER1840-101JR is based on Faraday\'s law of induction, which states that an electric current that passes through a wire will create a magnetic field. This magnetic field can then induce an electric current in another wire. The ER1840-101JR utilizes this principle to store energy in the form of a magnetic field.

The ER1840-101JR has a wide range of applications in electronic circuits due to its small size and low inductance. It is commonly used in filter circuits to reduce the amount of radio frequency interference. It can also be used as an input filter in power supplies to reduce the amount of ripple in the output voltage, as well as in dc-dc converters to stabilize the output voltage. It can also be used in analog circuits to provide harmonic damping, to limit the high-frequency signal content in the output of Oscillators, and to reduce the overall noise level of an electronic system.

The ER1840-101JR is an extremely versatile and useful component that is widely used in a variety of applications. Thanks to its small size and low inductance, it is ideal for applications such as filter circuits, dc-dc converters and noise reduction. It can also be used in a variety of analog circuits, providing harmonic damping, limiting the high-frequency content in the output of oscillators and reducing overall noise levels. All in all, the ER1840-101JR is a highly reliable and cost-effective component that is widely used in both commercial and industrial electronic circuits.
