Ferrite Cores - Cables and Wiring

For most casual users, the technical phrase “ferrite cores” means very little. However, these components are actually a vital part of many electronics and computing designs. The RC28B1265 ferrite core in particular is one of the most popular components in this range, and is widely used due to its relatively low cost and versatility. In this article, we’ll discuss what ferrite cores are, the specific RC28B1265 model, and its application field and working principle.

What are Ferrite Cores?

Ferrite cores are small pieces of ferrite material, usually in the form of a winding core, which are used to conduct magnetic fields or to shield electronics from magnetic interference. Ferrite cores are made from a variety of ferrite materials, but the most common types are cobalt-magnesium ferrite, nickel-zinc ferrite, and aluminum-iron ferrite.

In general, ferrite cores are used in a wide range of electronic applications due to their low cost, low power dissipation, and good temperature stability. They are often used for the suppression or filtering of audio or other frequencies. Ferrite cores are also used in the suppression of electromagnetic interference (EMI), which is an issue due to the increasing complexity of modern electronics.

The RC28B1265 Ferrite Core

The RC28B1265 ferrite core is one of the most popular types of ferrite cores and is widely used due to its low cost and versatility. This core has a current rating of 1.2A, and its operating temperature range is from -55°C to +125°C.

The RC28B1265 ferrite core is a core of nickel-zinc ferrite material and is available in many shapes, such as wound coils, split cores, and clamshell cores. It is often used in the design of transformer windings, inductors, and chokes. The core is easily reversible, allowing for a high degree of applications.

Application Field and Working Principle

The RC28B1265 ferrite core is a versatile component that is used for a wide range of applications. It is used in the design of transformers, inductors, and chokes. It can also be used for EMI suppression, filtering of audio or other frequencies, and in the suppression of high-frequency noise.

The working principle of a ferrite core is based on the fact that its magnetic permeability changes with the applied magnetic field. When a current is applied to the core, it induces a magnetic field, which flows through the core and generates a back-EMF. This back-EMF opposes the current, causing the core to act as a resistor to the current, thus suppressing the noise. This is why ferrite cores are used for noise suppression.

The RC28B1265 ferrite core is a popular choice for many electronics designs due to its relatively low cost and versatility. Its current rating and temperature range make it suitable for a wide range of applications, from audio filtering to noise suppression. Its construction from nickel-zinc ferrite material also makes it a reliable and durable component.
