Ultracapacitor Announcements

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 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 series) so that they can make a selection based on their space, performance, and cost requirements. Both our PC series and our TPL 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.

Tecate Group Announces Availability of 3V Medium-Size Ultracapacitors

Tecate Expands Product Offering to Include 100F to 450F 3V Cells with the TPLH Product Series for High-Power Applications

Tecate TPLH ultracapacitorSan Diego, CA, May 21, 2018…Tecate Group announces the addition of the 3V TPLH™ series of ultracapacitors to its already extensive offerings. The 3V TPLH™ series offers a low-ESR solution for high-power applications with cell values ranging from 100F to 450F. The TPLH™ series of ultracapacitors are UL recognized and RoHS and REACH compliant, with a market-standard snap-in connector style.

The TPLH™ cells are ideal for use in robotics, material handling, military, wind-power pitch control, medical device, and uninterrupted power supply (UPS) applications. These cells provide peak-power shaving, emergency power, and primary power replacement for the previously mentioned applications and many others. The 3V cells in particular help increase stored energy capacity and power by over 20 percent in the same-size can as other, lower-voltage ultracapacitor cells. Working either in conjunction with or as stand-alone alternative to batteries, ultracapacitors help reduce maintenance requirements and can provide a longer life and cost-effective energy storage for applications that require extremely reliable backup power, pulse power, or voltage control.

Tecate's TPLH™ 3V ultracapacitor cells operate at a temperature range of -40oC to +65oC (with expanded operating temperature to +85oC with voltage derating to 2.5V), industry-accepted capacitance tolerances with a projected cycle life of 500,000 and a load life performance of 10 years.

Taiwan Begins Testing Supercapacitor-Powered, Cable-Free Rail System

The city of Kaohsiung, Taiwan, has begun testing the world’s only completely cable-free rail system. Instead of relying on an overhead network of power cables to move them, the light-rail trains employ supercapacitors with wireless charging systems to get them from station to station. Taiwan partnered with Spain-based company Construcciones y Auxiliar de Ferrocarriles (CAF) to build the trains, which can charge in only 20 seconds. Tecate Group is a distributor and integrator of Maxwell supercapacitor cells and modules.
