    RadioShack - 273-104 - Snap-On Ferrite Toroid RF Choke Cores, Two (2) Cores in Package.

    Reduce or eliminate on RFI (radio frequency interference) with this snap-together Toroid Choke Core. Effective "Roadblock" to Radio Frequency Interference. Easily use choke core on a phone, computer, AC, audio and coax cables. No cable cutting necessary - you simply wind it through the core.

    Fast 'n Easy Solutions to RFI Problems

    Helps reduce RFI (Radio Frequency Interference). Use on Phone, Computer, Keyboard, AC, Audio and Coax Cables.

    Use as close to the equipment as possible, wrapping the cord through the center of the coil until the core is filled. All turns must be wound in the same direction to avoid cancelling the effects of the core.

    No need to cut cable - Simply wind it through the core and snap together.

    Ferrite Split Core Chokes (Two per package)

    Effective to 500 MHz.

    Approximate Overall Dimensions: 1.62" X  1.125" X 0.396"

    Opening: 0.885" X 0.380" (7/8" X 3/8")

    Includes Detailed Instructions on Theory and Installation.

    Note: Some customer report using as a step up Transformer by winding primary and secondary coils driven at 60 Hz.
