Panasonic expands production of large hybrid capacitors in AI boom
Panasonic Industry is expanding production of its larger hybrid capacitors as demand ramps up for power supplies in AI datacentres.
These combine polymer aluminium electrolytic and specialty polymer capacitors for higher endurance, low equivalent series resistance (ESR), and higher tolerance for ripple and inrush currents, even in elevated temperature conditions.
There is particular demand for high-volume 6x6mm diameter capacitors as well as the more specialized devices at 10x10mm and above in the ZUU, ZC and ZS surface mount families.
Panasonic says it sees growing demand for these hybrid capacitors, supporting higher switching frequencies for higher efficiency power supplies, particularly in power supplies for AI processors in datacentres. The devices, operating at up to 80V with a capacitance of up to 1000 μF, also take up less space on the printed circuit board for smaller power supplies.
The ZUU series hybrid capacitor series has a ripple current handling capability of 6.1 Arms maximum (a 60% increase over our previous series) at both 125°C and 135°C, together with the largest capacitance value of 1,000 μF, an 80% increase over the previous series and the lowest ESR value of 8mΩ minimum.
The capacitors are also AEC-Q200 compliant for automotive applications such as pump, electric power steering, cooling fans, high current DC to DC converter and ADAS, but are also increasingly being used for high reliability power supplies. These include DC to DC converter and AC to DC converter in base stations, servers, routers and switches and inverter power supplies in robotics as they can withstand shocks of as much as 30G.
Panasonic is expanding the production at several of its sites in Malaysia to ensure continuity of supply, particularly for the 6x6mm and 10x10mm families.
