With the expansion of global data centers and the increasing penetration of new energy vehicles, switching power supplies are rapidly upgrading towards higher frequencies (switching frequencies exceeding 200kHz) and smaller sizes. Traditional aluminum electrolytic capacitors, due to their high high-frequency impedance and weak ripple tolerance, are gradually failing to meet the performance requirements of equipment. Recently, a key breakthrough has been achieved in high-frequency, low-impedance aluminum electrolytic capacitor technology. Through improvements in electrode materials and structural optimization, a core component solution for upgrading switching power supplies has been provided, attracting widespread attention in the European and American electronics manufacturing industries.

This technological breakthrough focuses on two core aspects: First, the use of high-purity aluminum foil and nano-level oxide film technology reduces the capacitor’s impedance by more than 35% at 100kHz, significantly reducing power loss during high-frequency operation. Second, an innovative electrolyte formula incorporates high-temperature resistant organic additives, enabling the capacitor to maintain stable impedance characteristics even at 125℃, solving the industry pain point of a sudden increase in impedance at high temperatures in traditional products. Data from the Power Supply Manufacturers Association (PSMA) shows that switching power supplies equipped with this new type of capacitor achieve an efficiency of over 94%, a 2-3 percentage point reduction compared to traditional solutions, while also reducing heat loss by 25%, significantly extending equipment lifespan.

In practical applications, this technology demonstrates exceptional adaptability: for data center server power supplies, its low impedance effectively suppresses high-frequency ripple, ensuring stable server operation; in new energy vehicle onboard switching power supplies, its high-temperature resistance meets the demands of high-temperature cabin conditions, reducing the risk of power failures due to capacitor failure. Currently, several European industrial power supply companies have initiated bulk purchases, and the penetration rate of high-frequency, low-impedance aluminum electrolytic capacitors in the global switching power supply market is expected to exceed 40% by 2026. This technological breakthrough not only drives the upgrading of the aluminum electrolytic capacitor industry but also helps the global electronics industry achieve its energy efficiency and low-carbon development goals.
