    Default ferrite coil

    I''m just wondering if anyone can link me to a site with an explanation put into layman's terms.

    I searched around and can find everything but.



    On my first two RMA's, the material covering it is like a thin,green vinyl tape?. On the one I have now, it's much thicker(pink) in the picture.

    All you ever wanted to know about inductors but were afraid to ask:

    http://electronics.howstuffworks.com/inductor.htm
    http://www.ibiblio.org/obp/electricC.../DC/DC_15.html

    The second link is a more technical reference.

    http://en.wikipedia.org/wiki/Ferrite_(magnet)

    This is the ferrite used on VGA cables and some PCI-e cabling. That Tagan 1100 has one on it's mains power cored, why? I do not know.
    Be sure to read down to uses.
    Worth a good looking over. http://www.badcaps.net/

    Simply put, a ferrite absorbs E-M radiation at a particular frequency band and converts it into heat.

    you are talking about a choke, not a coil like he has asked about and shown pictures of. also, a choke is a very basic inductor, used to block high frequency AC current on a DC line.

    now on to coils like you asked.


    a ferrite coil is an inductor. they can have many different cores fro ferrite cores to air cores depending on the characteristics of inductance needed. also, inductance is measured in henries.

    the winding of wire creates an electromagnetic force when current is applied, this is used to resist changes in current.

    simply put, inductors are passive energy storage devices that resist change in current.

    or even simpler, they filter AC current from a DC line.
