.Fixed Inductors
Fixed inductors have numerous applications in power electronics circuits, and are particularly useful in switch-mode power supplies and other high-frequency circuits. Amongst them, the PM20-R27M is an inductor with a high current, high-frequency operation. This article will discuss the general application and working principles of the PM20-R27M.
The PM20-R27M is a 20A, 27uH, high-frequency inductor with superior current and ripple immunity. It is ideal for use in high-frequency power applications, such as switch-mode power supplies, and provides high-frequency performance without compromising the size of the package. The PM20-R27M is designed with a self-leaded construction to reduce resistance and improve insulation. It can be used in a wide range of operating frequencies, including up to 3MHz, and features a low DC resistance and high efficiency.
The PM20-R27M is typically used in circuits that require high current, high-frequency performance. In particular, it is commonly used in switch-mode power supplies for DC-DC conversion. In these circuits, the inductor provides the necessary filtering of power supply ripple and act as a source of stored energy. In addition, the inductor can be used to convert high-frequency AC signals to low-frequency AC signals by carrying out energy transfer to the load. The inductor and load form a parallel circuit known as a filter.
The working principle of the PM20-R27Minductors involves the principles of electromagnetic induction. Electromagnetic induction occurs when a conductor moves through a magnetic field, which induces a current in the conductor. This current, called the induced current, produces a magnetic field in the opposite direction to the initial magnetic field. This phenomenon is used in the construction of the PM20-R27M inductors, which is comprised of a coil of wire wrapped around a core material, which is usually a ferrite material. When current passes through the coil, it induces an opposing magnetic field in the core material. This opposing magnetic field creates a back-emf in the coil, which counteracts the current, resulting in a lower voltage across the load.
Overall, the PM20-R27M is an effective and reliable inductor for use in power electronics circuits. It has a wide range of applications, including in switch-mode power supplies and other high-frequency circuits. It is designed with a self-leaded construction to reduce resistance and improve insulation, and features an operational frequency of up to 3MHz and high current rating. The working principle of the PM20-R27M inductor involves the principle of electromagnetic induction, which creates a back-emf in the coil, resulting in a lower voltage across the load.
