Fixed Inductors

Fixed inductors are passive electronic components, consisting of a coil of wire. This coil is wound on an inserted core, forming a loop or circuit for current to pass through. The inductors sole purpose is to create and maintain a specific amount of electric current, or inductance, in the circuit.

The MLF2012K470KT000 is one example of a fixed inductor. It is a 0402 chip sized component with extended operating temperature range and high-temperature stability. It is composed of a tiny coil of wire on a ferrite substrate surrounded by a ceramic cover.

The primary application field for this model of inductor is high-frequency and high-temperature applications. It is used in applications such as power conversion circuits, filters, and resonators for integrated circuits and RF power amplifiers. This fixed inductor operate in frequencies up to 10GHz, providing high accuracy and low signal loss in such extreme conditions.

The working principle of the MLF2012K470KT000 fixed inductor is simple. An electrical current creates a magnetic field that induces an induction voltage in the wire. This induction voltage is proportional to the number of turns in the wire, and the speed of the current—in this case, the frequency of the current. The result is a relatively large inductance along the wire channel and across the substrate.

The inductor has two main functions—as a buffer and an adjustable smoothing filter. Basics of inductance prevent large and rapid fluctuations and transitions in the wavelength by providing a buffering effect. This preserves the wave contents from uncontrolled disturbances. As an adjustable filter, the inductor will allow low-frequency waves in, but reject surprisingly high-frequency waves.

Part of the specialty of the MLF2012K470KT000 is in its ability to maintain its performance in high-temperature environments. This specific model has up to 150°C rated operating temperature range. Special materials are used including a low-reluctance ferrite substrate and ceramic cover for improved thermal resistance and stability.

This fixed inductor exhibits exceptional performance within its specified temperature range, with minor variation in wire resistance, self-resonance, turn-to-turn capacitance, power rating and inductance. This makes it an ideal solutions for challenging, extreme environments such as automotive, aerospace, and far eastern industrial applications.
