Fixed inductors, also known as choke coils, are electrical components that are primarily used for energy storage. They can also be used to limit current in certain applications. The PCMB133E-2R2MS is a fixed inductor developed by Panasonic Corporation. It is a medium-size fixed inductor with a small pin pitch that is suitable for high-density mounting. This article will discuss the applications and working principles of the PCMB133E-2R2MS.

Applications

The PCMB133E-2R2MS is designed for applications in consumer electronics, such as cell phones, laptops, and other portable devices. Its small size allows it to be used in high-density mounting applications, making it a popular choice for miniaturized electronic platforms. The PCMB133E-2R2MS is also suitable for high-frequency circuit applications, such as SMPS or TV/CD/DVD writers, since its small size and low equivalent series inductance allow for high-speed performance. Additionally, the PCMB133E-2R2MS is suitable for audio equipment applications since its low internal resistance reduces noise.

Working Principle

The PCMB133E-2R2MS is an inductor, which means it stores energy in a magnetic field. It consists of a conducting wire wound around a core of ferrite or iron powder, which can be either in a cylindrical or toroidal shape. When a current passes through the wire, it creates a magnetic field around the core. This magnetic field is what stores the energy. When the current is removed, the magnetic field collapses and releases the stored energy as a current. This allows the PCMB133E-2R2MS to act as an energy reservoir, which can be used to control the current flow in a circuit. This ensures that the current is limited and does not damage the circuit.

Conclusion

The PCMB133E-2R2MS is a medium-size fixed inductor that is suitable for high-density mounting applications. It is suitable for applications in consumer electronics, such as cell phones and laptops, and for high-frequency circuit applications, such as SMPS or TV/CD/DVD writers. Additionally, it is suitable for audio equipment applications, as its low internal resistance reduces noise. The PCMB133E-2R2MS is an inductor that works by storing energy in a magnetic field and then releasing it as a current when the field collapses.
