Tecate Adds to Its Already Extensive Product Lineup With New High-Temperature-Capable Ultracapacitors Cells
SAN DIEGO, June 1, 2026 /PRNewswire-PRWeb/ -- Tecate Group today announced the expansion of its ultracapacitor product offerings with new cells rated for operation up to 105°C (221°F). The new TPLT product series is rated at 2.3V and currently includes four sizes: 3.3F, 4F, 6F, and 11F. Additional sizes are in development.
Tecate Group's current TPL and TPLH series ultracapacitors are rated for operation up to 65°C (149°F), or up to 85°C (185°F) with voltage derating. The new TPLT series delivers a 60% improvement in high-temperature performance over these existing technologies.
High temperatures can significantly influence ultracapacitor performance by accelerating electrolyte decomposition, increasing self-discharge, and reducing lifetime due to faster aging of electrode materials and separators. Elevated temperatures may temporarily lower internal resistance and improve power delivery, but prolonged exposure typically leads to capacitance decay and reliability issues. Tecate Group's new TPLT series improves application performance by helping maintain stable electrical characteristics and providing longer service life in harsh environments such as automotive under-hood systems, industrial equipment, and oil and gas electronics. A higher temperature rating reduces the need for active cooling, enables more compact system designs, and improves overall system robustness and uptime, especially in applications where thermal management is difficult or ambient temperatures are consistently high.
