Fixed inductors refer to the inductors with fixed inductance, which are usually made of air core or iron core coils. The coils are insulated by specific materials, and the electrical connections are made of metal wires or printed. MLZ2012M2R2HTD25 is one of the fixed inductors with an unusually small size. It is widely used in various electronic devices due to its small size, steady performance, and good reliability.

Application Field

MLZ2012M2R2HTD25 is mainly used in electronic circuits, as a local power supply, low power filtering, power stabilization, and interference attenuation. Due to its small size, it is suitable for applications in microelectronics, MOS/IC circuits, multi-layer chip boards, digital signal systems, etc. It is also specifically used in electronic circuit modules, such as miniaturized signal transmission circuits, power amplifiers, and other circuit applications.

Working Principle

MLZ2012M2R2HTD25 consists of two parts, the core and the winding. The core material is usually made of metal, such as iron, nickel-iron alloys, permalloy, and iron-manganese alloys. The core acts as a magnetic circuit, providing a path for the magnetic flux. The winding is wound around the core. When an alternating current flows through the winding, a magnetic field is created due to the current\'s changing direction. This magnetic field intersects with the core to create a magnetic flux.

Within the core, the flux lines set up a closed-loop circuit, thereby inducing a voltage in the winding. The number of lines of force corresponds to the magnitude of the current. The magnitude of the current is determined by the size of the inductance. Based on Ohm\'s law, the reactance of the inductor is proportional to the frequency of the current flowing through the circuit, which is described by the formula X = 2πfL, where X is the reactance of the inductor, f is the frequency, and L is the inductance.

The MLZ2012M2R2HTD25 inductor stabilizes the current that flows through electronic circuits, enabling them to run more efficiently. It also filters out noise, reduces voltage declines, and provides a steady voltage to the components. The inductors are usually connected in series with a large capacitor to form a ladder filter for matching and improving the quality of the audio output.
