Fixed Inductors

A Fixed Inductor is typically a wound inductor, usually formed by winding a coil of copper wire around a core material. Though other materials are sometimes used, the most common core material is iron. The purpose of the core material is to keep the inductance of the inductor static and also to help keep the field produced from the inductance contained. This type of inductor is commonly used in radio circuits and other electrical circuitry because of their highly stable characteristics.

VLS5045EX-1R0N

The VLS5045EX-1R0N is an example of a Fixed Inductor. It is a very small, axial-lead, surface-mounted device. It was specifically designed for applications requiring higher inductance with minimal size. The inductor features a ceramic body for increased stability under temperature changes. It also has a wide operating temperature range (-40° to +105°C).

Application Field

The VLS5045EX-1R0N Fixed Inductor is commonly used in automotive applications. It is particularly suited for low and high frequency noise filtering, energy-saving lighting circuits, as well as audio circuits. It is often used in applications where space and efficiency are critical, such as in compact lighting solutions, engine control units, and in-car entertainment systems.

Working Principle

The VLS5045EX-1R0N Fixed Inductor works through inductance, which is the measure of the amount of energy stored in a magnetic field. When current passes through the inductor, a magnetic field is generated which then induces a voltage in the inductor. This voltage opposes the original applied current, thus creating a voltage drop across the inductor. This voltage drop in the inductor causes the inductor to act as a filter, allowing only AC current to pass and blocking DC current.

The VLS5045EX-1R0N also has a high Q factor which is a measure of the amount of energy stored in the inductor\'s magnetic field. A higher Q factor means that the inductor is able to store more energy than a lower Q factor inductor, thus making the VLS5045EX-1R0N ideal for applications that require efficient filtering of high frequency signals.

The VLS5045EX-1R0N also has a very low current noise, making it ideal for use in audio filters and power supplies. This low noise level allows it to be used in low-noise audio filters, power supplies, and motor speed control circuits.

Overall, the VLS5045EX-1R0N Fixed Inductor is a highly efficient device for applications that require high levels of inductance in a compact size. With its wide operating temperature range and low current noise, it is a great choice for many automotive and audio applications.
