Common Mode Chokes

Common mode chokes, also known as differential mode chokes, are becoming increasingly important components in electrical circuits. They protect devices and systems from the detrimental effects of interference, as well as providing protection against electrical noise. The UF1815SG-500Y5R0-01 is a high quality, high current, common mode choke designed for a variety of applications. In this article, we will explore the different application fields and working principles of the UF1815SG-500Y5R0-01.

Application Field

Common mode chokes are used to reduce power line noise and suppress interference in a variety of industries, including automotive, telecommunications, medical equipment, industrial automation, and datacom. The UF1815SG-500Y5R0-01 is well-suited for these applications due to its high current capability (5A) and low EMI noise levels. This common mode choke can also be used in devices that require differential line protection, such as sound cards, HDDs, GPS systems, and analog-to-digital converters.

Common mode chokes are also used to filter common mode radio-frequency interference (RFI) in electrical equipment. In radio-sensitive environments, the UF1815SG-500Y5R0-01 can reduce the effects of harmonics, transients, and other disturbances which may be present in signals. The device has excellent common mode line-to-ground isolation, which helps to keep noise out of data signals.

Working Principle

Common mode chokes, like the UF1815SG-500Y5R0-01, are designed to limit the flow of common-mode current, while allowing differential mode current to pass unimpeded. The device operates by creating a magnetic field which cancels out any AC component of the current flowing through the device. This magnetic field is created by passing a DC current through two coils of wire, each wound around a core of ferrite material.

The core material of the UF1815SG-500Y5R0-01 is designed to be highly permeable, allowing a large magnetic field to be created without increasing the component’s size. The device also features a high saturation flux density, meaning it can absorb large amounts of common-mode current. The combination of these two features allows the device to effectively filter out unwanted signals.

Common mode chokes are used in a variety of industries due to their ability to protect systems from electrical noise and interference. The UF1815SG-500Y5R0-01 is a high quality, high current common mode choke with excellent common mode line-to-ground isolation. It is well-suited for applications requiring reliable filtering of signals against radio-frequency interference, harmonics, transients, and other disturbances.
