A sub-type of electrolytic capacitors is the aluminum polymer capacitor, sometimes known as polymer electrolytic capacitors or simply polymer e-caps. These capacitor types differ from others in that conductive polymers, rather than liquid electrolytes, are employed.
A liquid electrolyte and a solid polymer electrolyte are combined in hybrid polymer aluminum electrolytic capacitors. These types are distinguished by low ESR values, low leakage currents, and insensitivity to transients; nonetheless, they have a service life that varies with temperature, much like non-solid e-caps.
These capacitor types differ from others in that conductive polymers, rather than liquid electrolytes, are employed. This calls for a unique processing step that is completed throughout production.
The still-liquid monomer that has been impregnated in lieu of electrolyte in the separator paper is crosslinked to a solid polymer during this chemical reaction, known as polymerization, which is carried out by heating. Usually, this procedure is carried out at a temperature of around 100 °C. The polymer is permanently solidified after it is finished.
The global polymer aluminum electrolytic capacitor market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The JX Series SP-Cap Conductive Polymer Aluminum Electrolytic Capacitors from Panasonic are available. The new capacitors increase the dependability of power supply circuits used in servers and other increasingly advanced communication base stations.
They provide high-temperature and high-humidity durability with long life.
Axial hybrid-polymer aluminum electrolytic capacitors have been introduced by TDK Corporation, a pioneer in electrical solutions for the smart society with headquarters in Tokyo, Japan.
The B40600 / B40700 series is designed for rated voltages of 25 V and 35 V and has a capacitance range of 780 F to 2200 F. It provides extremely low ESR values over a broad temperature range.
