Fixed Inductors play an essential role in various electronic circuits and systems since they are the devices responsible for storing energy in the form of a magnetic field. The 1025-28F series from EPCOS falls into this category providing an extensive range of SMD inductors with low DC resistance, high saturation current, and excellent temperature stability. In this article, we will take a closer look at the application fields of 1025-28F as well as its working principle.

Application Fields

The 1025-28F series of SMD inductors is especially designed for use in battery-powered electronic appliances such as mobile phones, PDAs, digital cameras, and similar electronic gadgets. It features superior magnetic shielding, higher current ratings, and are constructed using high-frequency materials that minimize losses due to eddy currents. This makes them ideal for use in common-mode chokes, low-power and high-current supply circuits, and other various circuits that require inductor elements. Apart from this, the 1025-28F series can also be used in power supply filter chokes across switch-mode power supplies, and low-dropout regulators. They are also used in SMPS circuits, where their good frequency characteristics enable precise operation across a broad range of frequencies.

Working Principle

The 1025-28F series of SMD inductors works on the principles of electromagnetic induction. The device consists of two terminals through which electric current passes, which induces an electromotive force in the conductors thus producing a magnetic field. The two terminals are either connected to each other or connected to ground. This causes the electrons in the current to move in a circular fashion, which induces the magnetic field. As the current increases, the magnetic field increases as well, thus creating a constant opposition to the current.

The main characteristics of the 1025-28F series of SMD inductors are its high current capacity, low DC resistance, low self-capacitance, and high frequency response. This makes them suitable for use in power supply filters, power conversion circuits, and various other electronic applications. In addition to this, the 1025-28F series also features an exceptionally low-profile design, low electrical noise, and a wide operating temperature range.

In conclusion, the 1025-28F series of SMD inductors from EPCOS provides an extensive range of devices for use in various battery-powered electronic applications. They feature superior magnetic shielding, higher current ratings, and are constructed using high-frequency materials. In addition to this, the 1025-28F series features an exceptionally low-profile design, low electrical noise, and a wide operating temperature range, making them ideal for a variety of applications.
