KEMET Aluminum Organic Capacitor (AO-CAP)
A700 Series Polymer Aluminum
Overview
The KEMET Aluminum Organic Capacitor (AO-CAP) is a solid
state aluminum capacitor with an aluminum oxide dielectric and
conductive polymer cathode. The use of the conductive polymer
cathode results in very low ESR and improved capacitance
retention at high frequency. AO-CAPs may be operated at steady
state voltages up to 100% of rated voltage (no derating) with
equivalent or better reliability than tantalum capacitors operating
at the recommended derated voltage.
The A700 Series AO-CAP offers the same advantages as the
polymer tantalum capacitors but also has the added advantages
of 125°C performance capability, higher ripple current handling
capability and a lower ESR range. Packaged with multiple
anodes/elements to reduce the depth that the signal must
penetrate, this parallel arrangement reduces the ESR further
still to achieve lower ESR than other types of surface mount
capacitors with similar capacitance ranges. With reduced ESR,
the enhanced capacitance retention at higher frequencies
provides the lowest total capacitance and an economical solution
for power applications.
Benefits
• ESR: 6mΩ to 70mΩ
• Voltage: 2V to 16V
• Capacitance: 6.8µF to 470µF

Ripple Current/Ripple Voltage
Permissible AC ripple voltage and current are related to equivalent series resistance (ESR) and the power dissipation capabilities of the
device. Permissible AC ripple voltage which may be applied is limited by two criteria
a. The positive peak AC voltage plus the DC bias voltage, if any, must not exceed the DC voltage rating of the capacitor.
b. The negative peak AC voltage, in combination with bias voltage, if any, must not exceed the allowable limits specified for
reverse voltage. See the Reverse Voltage section for allowable limits
Power capability is determined based on a 20°C temperature rise. A higher temperature rise and therefore higher power capability is
allowable as long as the ambient temperature plus temperature rise due to ripple current does not exceed the rated temperature of the
part.
The maximum power dissipation by case size can be determined using the below table.

Using the P max of the device, the maximum allowable rms ripple current or voltage may be determined.
I(max) = √P max/R
E(max) = √P max*R
I = rms ripple current (amperes)
E = rms ripple voltage (volts)
Pmax = maximum power dissipation(watts)
R = ESR at specified frequency (ohms)
