Datasheet

Maxwell Technologies BOOSTCAP® Ultracapacitors provide extended power availability, allowing critical information and functions to remain available during dips, sags, and outages in the main power source. In addition, it can relieve batteries of burst power functions, thereby reducing costs and maximizing space and energy efficiency. The ultracapacitor features a cylindrical design and an electrostatic storage capability that can cycle a million charges and discharges without performance degradation.

The K2 Series ultracapacitors are a third generation design that provides 2.7 volt operating voltage while improving Maxwell's BOOSTCAP high performance and high reliability on a high volume manufacturing platform. These cells are ideal for automotive subsystems, medical devices, UPS/backup power, wind turbine pitch control, and many other applications which require a pulse of energy that cannot be efficiently provided by a battery or power supply alone.

The K2 Series works in tandem with batteries for applications that require both a constant low power discharge for continual function and a pulse power for peak loads. In these applications, the device relieves batteries of peak power functions resulting in an extension of battery life and a reduction of overall battery size and cost.

The K2 Series is also an ideal source of back-up and pulse power. It can provide extended power availability, allowing critical information and functions to remain available during dips, sags, and outages in a power supply or battery change. In applications where power is need in spikes, the K2 Series provides a “green” power solution to reduce peak power demans on the grid, batteries or generators. And, like all Maxwell ultracapacitors, the K2 Series is capable of accepting charges at the identical rate of discharge.
