Spirax Coils is manufacturing Inductor Coils. Inductor Coils are basically solenoids composed of a conductor wound on a suitable magnetic core. This is why these inductors are also known as Hi-Q [High-Q] Inductors. Depending upon the core geometry and winding topologies, an Integrated Inductor Coil may or may not be susceptible to electromagnetic interference in their immediate ambience. Inductance is the phenomenon by which an inductor influences electrical current flowing in any circuit.
Spirax Coils offers Current Transformers, Pulse Transformers, Hi-Q Inductor Coils & Ethernet G703 Baluns & Ununs that are used in both digital and analogue electronic applications. The Inductor Coils are frequency dependant, generally blocking higher frequencies, while allowing lower ones to pass through. They form an integral part along with a suitable capacitor to form band-pass or band-reject filters.
