About the Tecate Group

Tecate Industries was founded by Ralph Scarano, an electronics engineer and entrepreneur with more than 60 years’ experience in the capacitor industry. With the vision that capacitors could be cost-effectively manufactured in Mexico, the company selected the border town of Tecate, BC, Mexico as the location of their first manufacturing facility. In 1987 a new division, Tecate Products, was founded to meet the needs for contract manufacturing and full turn-key design for the audio and automotive industries. Within a few short years Tecate Products received QS9000 certification. A third division was added to the Tecate Group in 2004 to begin marketing ultracapacitors and design and build custom ultracapacitor modules. This unique technology used for short term power requirements lends itself very well to module design as most applications require multiple components and active or passive balancing circuitry. Tecate has pioneered the concept of off the shelf modules which allow customers to test the technology before a custom module is designed. Design engineers worldwide are exploring ways to use ultracapacitors as a green energy source instead of, or as a supplement to, batteries.
