High Capacity Capacitor, 2.85V-3400F, Threaded terminals

Manufacturer's part number :


Manufacturer Maxwell Technologies Inc.

Maxwell Technologies Inc.

Description :

The BCAP3400P285K04 ultracapacitor is the 2.85-Volt, 3400-Farad cell making it the most powerful cell available in the industry-standard 60 mm cylindrical form factor.

It is also the first cell to incorporate Maxwell’s DuraBlue™ Advanced Shock and Vibration technology. Products with DuraBlue technology are tested to some of the most demanding environmental requirements for transportation, increasing vibrational resistance by approximately three times and shock immunity by four times when compared to ultracapacitor-based competitive offerings.
