At 20 to 120mΩ, ESR values for hybrids are higher than other types of polymer capacitors, but still very low considering the higher power applications they address (see sidebar). • Great frequency characteristics.
The liquid portion of the electrolyte, meanwhile, can withstand high voltages and provide higher capacitance ratings due to its large effective surface area. The hybrid capacitors offer a voltage range from 25 to 80 V and capacitances between 10 and 330 µF.
Polymer hybrid aluminum capacitors. As their name suggests, these capacitors use a combination of a liquid and conductive polymer to serve as the electrolyte (see Figure 4) and aluminum as the cathode. Think of this technical approach as the best of both worlds: the polymer offers high conductivity, and a correspondingly low ESR.
Depending on the specific model, these capacitors cover a voltage range from 2-25 V and offer capacitances between 2.2-560 µF. The distinguishing electrical characteristic of these polymer capacitors is their extremely-low equivalent series resistance (ESR).
Hybrids are compact. Given the ongoing push to miniaturize electrical equipment, the size of capacitors has taken on a growing importance. Surface-mount hybrid capacitors measuring just 6.3 x 5.8 mm can handle 35 V and offer a capacitance of 47 µF. The small size can save a significant amount of board space.
To take a few examples, hybrid capacitors have significantly better endurance and humidity resistance than either their electrolytic or polymer counterparts. Hybrids also have significantly higher tolerance for large ripple currents, inrush currents, and elevated temperature (See Figure 9).
