Principle of magnetic ring anti-interference:
Anti-interference magnetic ring, also known as EMI absorbing magnetic ring, magnetic beads on the multi-stranded cable EMI interference suppression, including noise and spike interference on the power line, which at the same time has the ability to absorb EMI absorbing magnetic ring static impulse collection, so that electronic equipment to achieve the corresponding international standards of electromagnetic compatibility (EMI/EMC) and electrostatic discharge.
The use of a multi-core cable or a bunch of multi-stranded cable can be threaded in it. Threading more than once can enhance its effect. The absorption characteristics of the toroidal beads are usually measured in terms of impedance at 25 MHz and...
Expanded Information:
Electromagnetic compatibility is a term that refers to the ability of a magnetic ring to be used in a variety of applications. p>Electromagnetic compatibility means that a certain electronic device neither interferes with other devices nor is affected by them at the same time. EMC is one of the most important indicators of product quality, as is the familiar safety. Safety involves people and property, while electromagnetic compatibility involves people and environmental protection.
EMC design should be part of the comprehensive design of any electronic device and system. It is far more cost effective than other methods of trying to make a product EMC compliant.The main design techniques for EMC include: electromagnetic shielding methods, filtering techniques for circuits, and grounding designs that include grounded component laps that should be given special attention.
