Tecate Group, a supplier of capacitors and ultracapacitors, has made available custom and standard ultracapacitor cells and modules that are specifically engineered for today's automatic meter reading (AMR) and smart grid applications.

According to Tecate, the RoHS-compliant ultracapacitor cells and modules are ideally suited for use in low profile or small footprint systems and products and for today's AMR and smart grid applications in which consumption, diagnostic, and status data is collected from water or energy metering devices (gas and electric), and then transferred to a central database for billing, troubleshooting, and analysis.

Parts of the ultracapacitor cells and modules are members of Tecate's UL 810-recognized PowerBurstfamily, which is comprised of the general purpose TPL and TPLS Series of 2.7V cells and the TPLE series of 2.3V cells featuring a -40 to 85C temperature range.

The flat prismatic PC5 and PC10 series of 2.5V cells are provided for applications where height is limited while the low- and ultra-low profile PB/PBF/PBL/PBLL Series of 5.0V and 5.4V devices are offered for applications requiring modules.

Tecate said the parts offer OEMs and ODMs the competitive advantage of ensuring product and system safety while minimizing the time and expense associated with additional component-level testing.

To speed up time-to-market, Tecate said that its customization capabilities include the use of SolidWorks3D CAD (MCAD) software to facilitate superior design flexibility, responsiveness, and application engineering support. The high power density cells feature capacitance values ranging from 0.5F to 400F and low Equivalent Series Resistance (ESR).�Modules withstand over 500,000 cycles, Tecate said.

The parts provide battery-free "last gasp" power, and satisfy the high current pulse requirements of AMS technology, Tecate said. They also provide critical backup power during power outages to ensure uninterrupted communication to and from the grid. They are also capable of operating at low temperatures (-40C), with parts supplement batteries for low temperature boost, and relieve batteries of peak power functions to extend batteries' life.

Tecate's PB/PBF/PBL/PBLL/ Series of modules are available with active or passive cell balancing, and with radial leads or flexible wire and connectors to eliminate the need for soldering. They are provided in an array of standard and custom high voltage, advanced circuitry and packaging options to meet application- specific requirements.?.

Average prices for PowerBurst ultracapacitor modules range from $12.00 to $92.00 in quantities of 50+. In quantities of 1K, average pricing for 2.3V PowerBurst ultracapacitor cells ranges from $1.25 to $7.75; $7.00 to $17.00 for 2.5V cells; and $1.00 to $19.00 for 2.7V cells.
