As for aggressive costs, we believe that you will be searching far and wide for anything that can beat us. We can state with absolute certainty that for such high-quality at such rates we have been the lowest around for Monitor Display Cable, An Inductor, Common Mode Inductor, "Passion, Honesty, Sound services, Keen cooperation and Development" are our goals. We've been here expecting close friends all around the earth!

Factory source Ferrite Inductor - Toroid choke with base – Mingda Detail:

Common mode inductance can also be called common mode filter or power filter. The common mode inductor is a common mode interference suppression device with ferrite as the core. The CMC series common mode inductors produced by Fenghua Hi-Tech adopt ferrite cores. Double wire and wind. The low differential mode noise signal suppresses the interference source, and the coupling coefficient is large. It has little effect on high-speed differential signals, and it is difficult to deform in high-connected signals. It has a good suppression effect on high frequency common mode noise. At the same time, it has a smaller size. This series of common mode inductors are suitable for notebook computers, digital video cameras and other equipment with demanding space requirements. Common mode inductance is two sets of coils with the same number of turns, the same wire diameter, and the opposite winding directions on the same iron core.Ming Da common mode inductors with base is designed for different noise levels and signal frequencies. Mass production of two packages, 0805 and 1206, in the range of 67 ohms to 2.2k ohms, a total of 14 mass production models. The characteristic is: Because the winding directions of the two sets of coils on the same iron core are opposite, the iron core is not afraid of saturation. Most magnetic core materials used in the market are high-conductivity ferrite materials.

Just provide basic information from your engineer, we could help to customize ideal product for you.
