Magnetics, Inductors, and Transformers

API Technologies produces a broad range of custom magnetic devices. These include current transformers, power inductors, chokes, air coils and custom application-specific solutions.

Our magnetics group combines the people, products and technologies of Filtran, RTI Electronics, and Keytronics into a single entity ready to satisfy your magnetic requirements. API Magnetics is a key supplier to many of the world's leading OEMs, serving the military, aerospace, medical, telecom, transport, RF and industrial/test measurement markets.

Available totally encapsulated, with or without wound primary turns and loading resistor. Current range of 3.5 to 800 amps.
Precision wound, heavy-duty toroidal inductors. Stores energy as a magnetic field, can delay and reshape alternating current.
Available in medium-current and high-current toroid type. Open winding, semi-encapsulated, and encapsulated construction.
High-quality noise rejection filter. Precision wound, heavy-duty toroidal inductor in both 120 and 240 volt models.
Convert power-level voltages from one level or phase configuration. Lower mechanical leakage, lower electrical noise, and mechanical hum.
Transform line voltage to any other voltage. Value ranges from 3 to 100,000 volt-amps, economical "channel frame" construction.
Impedance and line matching transformers. Broadband and voiceband transformers used for datacom and telecom applications.
Air Coil Inductors offer a critical benefit of having no magnetic core. Inductance is unaffected by the current it carries.
