VLS4012ET-100M Application Field

The VLS4012ET-100M is a high-performance, axial-lead, non-shielded, Ferrite-Core Inductors. It has an inductance of 0.1μH and can operate up to a temperature of +150°C. The VLS4012ET-100M is designed to support a wide range of applications, such as LCD TVs, digital cameras, DVD players, and PDAs. It is also suitable for mobile communication applications, such as cellular phones, WAN, and wireless base stations. In addition, the VLS4012ET-100M can be used in industrial motors, home appliances, and smoke detectors.

Due to its excellent electrical characteristics and properties, the VLS4012ET-100M is highly sought after in critical applications such as pulse circuits and high-frequency switching circuits. The Ferrite-Core Inductor has a low DCR for higher current handling and a high SRF for low EMI. Furthermore, it features low leakage current, high current rating, and low power losses. Its construction ensures excellent voltage-worthiness and high vibration resistance. It is also available in an extended temperature range, from -55°C to +150°C.

The VLS4012ET-100M is designed with a wide variety of shapes and sizes to meet the needs of different applications. It is available in flat-top and round-top coil shapes, as well as various other shapes. In addition, it is available in 2.5 x 2.0 mm, 2.0 x 1.2 mm, 5.0 x 4.0 mm, and other sizes. The VLS4012ET-100M is also certified to the RoHS directive.

VLS4012ET-100M Working Principle

An inductor is an electrical component that stores energy in a magnetic field. A Ferrite-Core Inductor, like the VLS4012ET-100M, consists of a magnetic core with a coil of wire wound around it. The core acts as a magnetic medium, allowing the inductor to store more energy than a typical air core inductor.

When an electric current flows through the coil, it creates a magnetic field around the core. This field interacts with the core, causing it to become magnetized. As the current increases, the magnetic field strengthens, which in turn increases the inductance of the component. The inductance is a measure of the amount of energy the component can store, and it is proportional to the coil\'s number of turns. The higher the number of turns, the higher the inductance.

In the VLS4012ET-100M, the Ferrite-Core material increases the inductor\'s inductance and provides it with the ability to handle higher currents and lower power losses. In addition, the Ferrite-Core also serves to reduce EMI emissions, making the VLS4012ET-100M ideal for high-frequency applications where EMI is a concern.

When the current passes through the inductor, it creates a voltage drop across the component. This voltage drop is known as the back EMF (electromotive force) and can be calculated using the formula: Back EMF = Vm x L, where Vm is the peak voltage, and L is the inductance. The higher the inductance, the higher the voltage.

The VLS4012ET-100M is designed to withstand extreme temperatures and conditions, making it an ideal choice for critical applications. Its construction ensures excellent voltage-worthiness and vibration resistance. Furthermore, its low leakage current and low power losses provide the necessary stability and reliability needed in demanding environments.
