Conductive polymer hybrid aluminum electrolytic capacitors, with the electrolyte fused with conductive polymer and electrolyte liquid, are suitable for automotive equipment, communication base stations, etc. which need compact and highly reliable components.
As described earlier, hybrid capacitors have improved the weak points of conventional aluminum electrolytic capacitors such as low-temperature characteristics, ESR characteristics, and high ripple through the adoption of a conductive polymer while keeping their advantages (safety, low LC).
Solid aluminum electrolyte capacitors have a solid electrolyte material — such as manganese dioxide or conductive polymer — for the cathode. They offer low ESR, low leakage current, low dissipation factor, and long life. However, they also have lower capacitance, lower voltage rating, and higher cost than liquid electrolyte capacitors.
A comparative analysis of aluminum electrolytic capacitors (AECs) is presented. Polymer hybrid AECs (PHAECs) apply solid conductive polymer with liquid electrolyte. Key impact categories and contributors of AECs are identified based on ReCiPe 2016. PHAECs have obvious environmental advantages over liquid AECs and polymer AECs.
Surface mount hybrid capacitors measuring just 6.3 x 5.8 mm can handle 35V and ofer a capacitance of 47μF. The small size can save a signiicant amount of board space. In a recent 48V power supply application, hybrid capacitors occupied just 13% of the board space required by aluminum electrolytic capacitors.
Polymer capacitors come in four main varieties, including the hybrid. Each type has diferent electrolytic and electrode materials, packaging and application targets: • Layered polymer aluminum capacitors use conductive polymer as the electrolyte and have an aluminum cathode (see Figure 1).
The capacitors have a prismatic shape, with low ESR and ESL, and the polymer dielectric is formulated to yield excellent self-healing properties.The capacitance and …
Hybrid aluminum electrolytic capacitors use a combination of liquid and solid electrolytes as the cathode. They offer a balance of capacitance, voltage rating, ESR, leakage current, dissipation factor, and life.
