Product Solutions for Elevated Temperature & Humidity Environments

With over forty years of expertise in passive component encapsulation, the Tecate Group has incorporated this tested and enhanced sealing process into 100% of its TPL/TPLH product line (0.5F-100F), with no change to the physical or electrical performance of the cell. Where other manufacturers and suppliers have chosen to offer special order parts at an increased cost to their customers, Tecate has implemented our encapsulation process at no additional cost. This feature mitigates the effects of elevated temperature and humidity environments by providing additional mechanical stability as tested up to 3000 hours*.

Tecate Group's ultracapacitors are manufactured to the highest degree of quality and reliability and are compliant with RoHS, REACH, and UL requirements. Our commitment to enhanced innovation in the development of customized cells and modules has enabled Tecate to become a worldwide-recognized supplier of ultracapacitors. Based on this heritage, Tecate is the sole ultracapacitor manufacturer offering standard and custom products that can withstand the negative impact of elevated temperature and humidity environments through robust sealing alternatives.

We are uniquely positioned as the only ultracapacitor company who provide two proven product solutions that address these adverse environments. Customers now have a choice between a flat, prismatic, and hermetically sealed cell (our PC series) or a cylindrical, radial-lead, enhanced-sealed cell (our TPL/TPLH series) so that they can make a selection based on their space, performance, and cost requirements. Both our PC series and our TPL/TPLH series are not only available as individual cells but also as the building blocks for our standard and customized modules. Both series offer exceptional value and are only available through Tecate Group and its authorized channel of sales agents.

Our customer base is varied and the applications are all demanding, from military avionics to smart grid, from data storage to robotics, from UPS to telematics. Real-world applications demand real-world solutions, many of which can only be provided by the Tecate Group.
