DuraBlue® 3000F - 3400F

Maxwell Technologies DuraBlue® Advanced Shock and Vibration Technology combines Maxwell’s patented electrode formulation and manufacturing process with a robust proprietary cell structure, resulting in a product line specialized for the most demanding shock and vibration requirements of the industrial and transportation industries.

Maxwell’s proprietary electrode process results in the formation of a durable and tough electrode with the benefit of significantly longer life compared with other energy storage technologies available. Maxwell’s innovative mechanical design behind the DuraBlue® product line achieves high performance and reliability for applications in the automotive, rail and hybrid bus markets.

Exceeding Industry Standards

he test standards for Maxwell’s DuraBlue® product line are IEC 60068-2-27 for shock and ISO 16750-3.

The acceleration for IEC 60068-2-27 is 100 G, four times higher than the acceleration of SAE 2464, the test standard for competitor Ultracapacitor cells.
The RMS acceleration for ISO 16750-3, Table 12 is 5.9 Grms, three times higher than SAE J2380 with an acceleration of 1.9 Grms.
