Fixed Inductors are electrical components, typically consisting of a coil of wire wrapped around a core, and made of ferromagnetic materials or air. Fixed inductors are used in many types of electrical circuits, primarily in applications such as filter circuits, power-supply design, and voltage regulation. The VLS4012T-2R2M1R4 is an example of a fixed inductor. This article will discuss the application field and working principle of this particular type of fixed inductor.

Application Field

The VLS4012T-2R2M1R4 fixed inductor is designed as a high current, high frequency inductor and noise suppressing device. It is suitable for applications such as power supplies, switch-mode power supplies (SMPS), ripple-reduction (MOV) filtering, ac-dc converters, switch-mode converters, and any application requiring a high current inductor and low DC resistance. It is built with an enameled copper wire winding, allowing for improved heat dissipation and high ripple current capacities. Its reliability and temperature characteristics make it suitable for demanding applications, many of which require up to 105°C operating temperatures, as it is rated for -55°C to 105°C.

The VLS4012T-2R2M1R4 has been designed to meet the EIA3695-200 standard, enabling it to meet the most widely used industry specifications, including commercial, industrial, automotive, and military. The device’s high current capacity and resistance to temperature rise makes it suitable for use inDC-DC converters and power supplies.

Working Principle

The principle of operation of a fixed inductor is based on electromagnetic induction, whereby an alternating magnetic field is produced by a coil of wire when an alternating current is passed through it. This induces a current in the adjacent turns of the coil, creating a magnetic field which opposes the change in the current. This effect is known as the inductance of the coil, and is measured in units of henries (H).

The VLS4012T-2R2M1R4 is a variable inductor that utilizes this principle of operation. At its most basic, the device consists of a core of ferromagnetic material, around which is wound a coil of enameled copper wire, connected to two terminals. When an alternating current is passed through the coil, it generates a magnetic field which then induces a voltage in the coil. The magnitude of the voltage depends on the inductance of the coil, which is determined by the number of turns of the coil, the core material, and the cross sectional area of the core.

The VLS4012T-2R2M1R4 is designed to have an inductance range of 2.2mH to 4.7mH, which is specified at 100kHz. This range of inductance allows for a wide range of applications with varying current requirements. Additionally, the device has a high DC current rating, with a maximum rated current of 10A. This makes it suitable for use in high current applications, such as DC-DC converters.

Conclusion

The VLS4012T-2R2M1R4 is a fixed inductor suitable for use in a wide range of applications in electronic circuits, primarily in power supplies, voltage regulators, and DC-DC converters. The device utilizes the principle of electromagnetic induction, with a coil of wire wrapped around a ferromagnetic core. This allows it to have a wide range of inductance values, from 2.2mH to 4.7mH, and a high DC current rating of 10A. Its reliability and temperature characteristics make it suitable for use in high temperature environments, making it a reliable and durable choice for any application.
