Introduction

At present, with PD fast-charging power continuously increasing and power density constantly rising, overall equipment places higher demands on capacitor capacity storage, ESR, ripple performance, as well as temperature rise and lifespan consistency. This also promotes upstream capacitor manufacturers to continuously iterate on materials, processes, and quality control to match the high-frequency, high-temperature, and long-cycle usage scenarios of fast-charging products.
Recently, while organizing teardown cases, Chargers Network noticed that Nantong Sankin’s FA, FT, and other high-voltage capacitors, as well as multiple series of long-life capacitors, have appeared in multiple devices from brands such as Anker and IKEA. The following will summarize the specifications and typical applications of different series for readers to quickly compare and select.
