TT Electronics, through its BI Technologies brand, has been an innovator in electronic components for 50 years. 

It has evolved and changed over that time, in form and in name, but most significantly we have retained our innovative spirit. Having introduced our initial range of wound transformers and inductors to the power conversion market in 1987, we have nearly 30 years of experience in the manufacturing of magnetics products. 

Our current range of magnetic components includes both power and signal products. We offer a range of transformers, inductors and chokes for applications in tansportation and industrial fields. 


TT Electronics plc is a global electronics company, distilled at the turn of the century from the engineering conglomerate TT Group plc, which had a history extending back to 1988. Just one year earlier, BI Technologies introduced an initial range of wound transformers and inductors for the power conversion market to establish their name within the Magnetics component industry.

BI Technologies itself has a history going back much further. Formerly Beckman Industrial, BI Technologies began in 1940 with a single innovation; the “Helipot” helical potentiometer (essentially a precision variable resistive divider) which is a principle still in use today. In the mid-1950s cermet (ceramic – metal) materials were developed to raise the operating temperature of resistive parts, and in the early 1960s, BI pioneered in the use of thick film materials to make compact resistor networks. The following decades saw a series of innovations in thin film precision networks, compact surface mount moulded networks, chip resistor arrays and power resistors.

Every day, all around the world, our components are used in every conceivable application. From home computers to super computers, heart monitors and guitar monitors, instrumentation for the dashboard and the space shuttle--if it is electronic, it probably relies on BI components.

Dynamic, focused, and rich in heritage, BI Technologies continues its evolution. An evolution driven by customer need and the technology that serves those needs.
