310 - 350 F, 2.5 V DC | D Cell Series
Maxwell Technologies' D Cell® series ultracapacitor cells are ideal for automotive boardnet stabilization, medical devices, uninterruptible power supplies, backup power and pulse, wind turbine pitch control, and many other applications requiring a pulse of energy that cannot be efficiently provided by a battery or power supply alone.
Designed as a cylindrical package similar in size to a standard D-size battery, models are available for higher peak power applications (310F cell) or more energy intensive requirements (350F). The radial design provides both high current capability as well as a high reliability board soldering.
The cells work in tandem with batteries for applications that require both a constant low power discharge and a pulse power for peak loads. In these applications, the ultracapacitor relieves batteries of peak power functions resulting in an extension of battery life and can allow a reduction of overall battery size and cost.
The 350F cell provides extended power availability, allowing critical information and functions to remain available during dips, sags, and outages in a power supply or battery change. And, like all Maxwell Technologies ultracapacitors, D-cells are capable of accepting changes at the identical rate of discharge.
