Telephone Coil

An item consisting of one or more turns of wire or similar conductive material. It is specifically designed for use in telephone circuitry for reducing cross talk by balancing capacitances, or impedance matching or providing inductive reactance for overcoming inherent capacitance, or inductive coupling where direct coupling is undesirable or discriminating against the flow of alternating current in favor of direct current.
