【Parameters】 -Product model:T157-125A.
【Material】 - The toroid transformer is made of ferrite, this is a ferrite ring, not a magnet. It has no magnetism.
【Features】 -The iron powder core has the characteristics of eddy current isolation, low magnetic permeability and interference suppression.
【Function】 - Toroid core can not only reduce electromagnetic interference but also improve signal integrity.
【Application】 -Ferrite rings are often used to suppress the interference of power lines and signal lines, and at the same time have the ability to absorb electrostatic pulses.
