Fixed Inductors

The PM428S-330-RC is an inductor designed for use in a wide range of applications requiring fixed inductor solutions. It is composed of a multi-layer ferrite core winding composition and is available in a number of varieties from different manufacturing companies. The core of the inductor consists of two or four winding layers, with one winding being coupled with two layers either being opposite or parallel to the other winding. The output is in the form of a static inductor, which has fixed frequency and linear or sinusoidal current characteristics.The PM428S-330-RC inductor is commonly used in applications such as switching power supplies, resonance circuits, and frequency filters, as these filtration systems require high frequency stability and energy storage. The inductor also requires excellent treble response in frequency filters and harmonic absorbers. The inductor also acts as a damper to reduce noise in switching power supplies and oscillators.The PM428S-330-RC inductor stands out for its high saturation current and low DCR. Its core holds up to 90% of its inductance compared to iron core inductors, making it suitable for high-current applications, such as switching power supplies and resonant converters. The inductor also provides low loss and high-frequency response due to its low DCR.The working principle of the PM428S-330-RC inductor involves the movement of an electrical current through a conductor, which in turn creates a magnetic field. This magnetic field holds energy, producing an inductive reactance and resonant frequency. The inductor stores the energy until a voltage drop occurs, causing the current to flow back to the original conductor. This process is then repeated and creates a signal that consists of a high-frequency resonant and sinusoidal wave.The PM428S-330-RC inductor offers a series of benefits for electrical applications. It is highly efficient and reliable, with a long service life and low magnetic leakage due to its ferrite core. The inductor is dimensionally small, making it convenient for use in a variety of spaces and applications. It is also cost effective, with a reasonable cost compared to other inductors in its category.Overall, the PM428S-330-RC inductor is a cost-efficient and reliable inductor solution for demanding electrical applications. Its ferrite core offers high saturation current and low DCR, with excellent high frequency performance due to its low DCR. The inductor is also small and fits into a variety of spaces, making it an ideal choice for a number of electrical applications.
