Since 1962, Torelco has been a supplier of electric coils and transformers of superior quality. We offer custom coils, solenoid coils, ferrite core coils & toroid wound coils to serve a range of industries.

Our toroid coil can be wound from .093in. inside diameter to 15in. outside diameter, using wire sizes from 7 AWG through 46 AWG in open or cased styles, varnish, or epoxy encapsulated. A variety of different bobbin styles and types are available, including flex leads, thru-hole pin bobbins, surface mount bobbins, and air core bonded bobbins. They can be made from materials such as powdered iron, nickel alloys, silicon steel, and more. Additional services include reverse engineering toroids, flex lead attachments, varnish/encapsulation, and many others. If your product is in need of special packaging, we have the versatility to create solutions to your unique conditions. Don’t force your design into a standard package. Let us customize packaging to provide a perfect fit for your application.

Our products have been utilized in industries such as medical, military, industrial, and electronics. Torelco is equipped to fill your requirements with the same attention to quality and service that our industry has come to expect. When you work with us, we will build to your exact specifications. You can expect no limits for the size of order (one or more), quick turnaround time, products built to your specifications, and customer service that is second to none.

Electric Coils

Electric Coils

An electric coil, or electromagnetic coil, is an electrical conductor that contains a series of conductive wires wrapped around a ferromagnetic core that is cylindrical, toroidal, or disk-like. Electric coils are one of the simplest forms of electronic components and provide...

Electromagnetic Coils

Electromagnetic Coil

An electromagnetic coil is an electrical coil that generates an electromagnetic field when electric current passes through it. The structure of an electromagnetic coil consists of a length of wire that is wound around a core, which can be a cylinder, bobbin, oval, or other...

Inductor and Inductor Coils

Inductor and Inductor Coils

Inductors are passive two terminal components of an electric or electronic circuit that are capable of storing energy in magnetic form. They oppose sudden changes in current and they are also called coils or chokes...

Solenoid Coils

Solenoid Coils

A solenoid coil is a common electrical component that uses a wire that is tightly wrapped around a core, usually made of metal, to generate an electromagnetic field. When an electrical current is passed through the coil, the electromagnetic field that is created provides energy for linear motion...

Toroidal Inductors

Toroidal Coil Circuitry

Toroidal inductors are passive electrical components that store energy in a magnetic field and resist changes in a current as electricity passes through it. They consist of insulated wires that are wound around a coil that has a donut shape...

Voice Coils

Voice Coils

A voice coil is a winding of a wire, usually copper, aluminum, or copper-clad aluminum that is wrapped around a former (often called a bobbin) and then attached to the apex of a speaker cone...

Electric Transformers

Electric Transformers

Electric transformers are static electrical machines that transform electric power from one circuit to the other without changing the frequency. An electrical transformer can increase or decrease the voltage with...

Isolation Transformers

Isolation Transformers

An isolation transformer, just like typical transformers, is a non-moving device that transmits electrical energy from one circuit to another without requiring any physical contact. It works on the idea of magnetic...

Three-Phase Transformers

Three-Phase Transformers

An electrical transformer is a passive machine that transfers electrical energy from one circuit to another using a magnetic flux to induce an electromotive force. Transformers are used to increase (step-up) or decrease (step-down) voltages without changing the frequency of the electric current...
