AI Data Centers Move EVANSCAPS into the Spotlight

AI Data Centers require ultra-high power density and reliability moving EVANSCAPS technology and performance into the spotlight.

Evans' hybrid capacitor technology was invented by David Evans in 1996, with patents assigned to Evans in 2003.  These capacitors combine a tantalum anode with a ruthenium oxide cathode, achieving:

⚡Very high capacitance density

⚡Ultra-low ESR (milliohm range)

⚡High maximum voltage ratings

These traits make them especially well-suited to AI power shelves, aligning perfectly with the stability, absorption, and low-impedance needs of AI data center 48 V and 12 V power distribution networks.

In this Signal Intergrity Journal, article, author Steve Sandler of Picotest, positions Quantic Evans hybrid capacitors as a proven, rediscovered technology that gives AI data centers the low ESR, high density, and long-term reliability they urgently need—making them stand out from competing capacitor options.
