Fixed inductors are electrical components consisting of a coil of insulated wire wound on a core of ferrite or other material. They are used for the inductance of a fixed amount of current—hence their name—in a variety of electrical circuits. The MLF1005VR39KT is a fixed inductor commonly used in switch-mode power supplies, voltage converters, and pulse-width modulation (PWM) applications.

The MLF1005VR39KT fixed inductor is manufactured by Murata Electronics North America. It offers high inductance values in a very small form factor. The component measures just 1x1mm and has a maximum height of only 0.5mm. It is well suited for use in portable and low-profile applications. It features a monolithic core and wire construction, and its superior performance is designed to reduce EMI in sensitive circuits.

The MLF1005VR39KT is a surface-mount type inductor that is rated for operation at a maximum temperature of 125°C. It is available in two versions; standard or extended (–AHD). The difference between the two is that the –AHD extended temperature version uses a higher saturation current core material for improved temperature performance.

The MLF1005VR39KT inductor has a typical inductance value range of 3.2 to 100nH and exhibits low DC resistance and low AC resistance (Q factor) at high frequencies. It is designed to operate over a wide range of frequencies, from low frequencies such as DC to high frequencies reaching as high as 10GHz. This wide-range operational bandwidth is desirable in many applications, for example, transmitting or receiving radio signals.

The MLF1005VR39KT inductor is suited for various applications in industrial, automotive, and consumer electronic products. It is well suited for use in power supplies, DC-DC converters, RF communication, and power amplifier circuits. For example, it can be used as a noise filter for sensitive analog circuits or to filter out high-speed switching noise in power supplies. It is also suited for use in voltage converters, amplifiers, and boosters.

The working principle of the MLF1005VR39KT is based on the principle of Maxwell’s equations. It is an inductor that stores energy in the form of a magnetic field. When a current is applied to the inductor, a proportional amount of magnetic flux is induced, and this magnetic flux produces a back EMF throughout the component’s coil. This back EMF is proportional to the rate of change of the current, and therefore the component “resists” the flow of current. The rate at which this back EMF is experienced is known as the inductance, and is the measure of the inductor’s performance.

Overall, the MLF1005VR39KT is an efficient and effective fixed inductor from Murata Electronics North America that can be used in many different applications. Its small form factor and excellent temperature performance make it ideal for use in portable and low-profile applications. Its wide frequency range and low DC resistance make it a desirable option for broadcast and RF communication circuits. With its superior performance, it can help reduce EMI in sensitive circuits.
