Aluminum Organic Capacitor (AO-CAP)
A798 High Humidity and High Temperature
Polymer Aluminum
Overview
The KEMET A798 Aluminum Organic Capacitor (AO-CAP)
is a solid state aluminum capacitor. The cathode is a
conductive organic polymer, which results in very low ESR
and improved capacitance retention at high frequency. AOCAPs may be operated at steady state voltages up to 100%
of rated voltage without the need to de-rate.
Since there is no liquid electrolyte, the A798 offers long
operational lifetimes, low ESR, and high operational
temperatures. The inherent low ESR renders the A798
suitable for high ripple current handling. The small
package size, high ripple current capability, high operating
temperature, low parasistics, and capacitance stability over
life span makes the A798 ideal for demand applications.
The A798 High Humidity and High Temperature Aluminium
Polymer capacitors deliver higher capacitance and
ESR stability under harsh environmental conditions.
Enhancements to the design and selected material upgrades
were introduced to deliver 1,000 hours at 85°C/85% RH rated
voltage and 125°C Endurance Life and Storage.

Aluminum Organic Capacitor (AO-CAP)
A798 High Humidity and High Temperature Polymer Aluminum
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
1. The positive peak AC voltage plus the DC bias voltage, if any, must not exceed the DC voltage rating of the capacitor.
2. 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 Pmax of the device, the maximum allowable rms ripple current or voltage may be determined.
I(max) = √Pmax/R
E(max) = Z √Pmax/R
I = rms ripple current (amperes)
E = rms ripple voltage (volts)

Density Level A: For low-density product applications. Recommended for wave solder applications and provides a wider process window for reflow
solder processes.
Density Level B: For products with a moderate level of component density. Provides a robust solder attachment condition for reflow solder processes.
Density Level C: For high component density product applications. Before adapting the minimum land pattern variations the user should perform
qualification testing based on the conditions outlined in IPC standard 7351 (IPC–7351).

Soldering Process
Please note that although the X/7343–43 case size can
withstand wave soldering, the tall profile (4.3 mm maximum)
dictates care in wave process development.
Hand soldering should be performed with care due to the
difficulty in process control. If performed, care should be
taken to avoid contact of the soldering iron to the molded
case. The iron should be used to heat the solder pad,
applying solder between the pad and the termination, until
reflow occurs. Once reflow occurs, the iron should be
removed immediately. “Wiping” the edges of a chip and
heating the top surface is not recommended.

KEMET’s families of surface mount capacitors are
compatible with wave (single or dual), convection, IR,
or vapor phase reflow techniques. Preheating of these
components is recommended to avoid extreme thermal
stress. KEMET's recommended profile conditions for
convection and IR reflow reflect the profile conditions of the
IPC/J–STD–020D standard for moisture sensitivity testing.
The devices can safely withstand a maximum of three reflow
passes at these conditions.

Storage
All AO-CAP Series are shipped in moisture barrier bags (MBBs) with desiccant and humidity indicator card (HIC). These
parts are classified as MSL3 (Moisture Sensitivity Level 3) per IPC/JEDEC J–STD–020 and packaged per
IPC/JEDEC J–STD–033. MSL3 specifies a floor time of 168H at 30°C maximum temperature and 60% relative humidity.
Unused capacitors should be sealed in a MBB with fresh desiccant.
The calculated shelf life in a sealed bag would be 12 months from a bag seal date in a storage environment of < 40°C and
humidity < 90% RH. It should be 24 months from a bag seal date in a storage environment of < 30°C and humidity < 70% RH.
If baking is required, refer to IPC/JEDEC J–STD–033 for bake procedure.

Note 5
1. The embossment hole location shall be measured from the sprocket hole controlling the location of the embossment. Dimensions of embossment
location and hole location shall be applied independent of each other.
2. The tape, with or without components, shall pass around R without damage (see Figure 4).
3. If S1 < 1.0 mm, there may not be enough area for cover tape to be properly applied (see EIA Standard 481–D, paragraph 4.3, section b).
4. B1 dimension is a reference dimension for tape feeder clearance only.
5. The cavity defined by A0, B0 and K0 shall surround the component with sufficient clearance that:
(a) the component does not protrude above the top surface of the carrier tape.
(b) the component can be removed from the cavity in a vertical direction without mechanical restriction, after the top cover tape has been removed.
(c) rotation of the component is limited to 20° maximum for 8 and 12 mm tapes (see Figure 2).
(d) lateral movement of the component is restricted to 0.5 mm maximum for 8 mm and 12 mm wide tape (see Figure 3).
(e) see Addendum in EIA Standard 481–D for standards relating to more precise taping requirements.

Packaging Information Performance Notes
1. Cover tape break force: 1.0 kg minimum.
2. Cover tape peel strength: The total peel strength of the cover tape from the carrier tape shall be:
Tape Width
Peel Strength
8 mm
0.1 to 1.0 newton (10 to 100 gf)
12 mm
0.1 to 1.3 newton (10 to 130 gf)
The direction of the pull shall be opposite the direction of the carrier tape travel. The pull angle of the carrier tape shall be
165° to 180° from the plane of the carrier tape. During peeling, the carrier and/or cover tape shall be pulled at a velocity of
300 ±10 mm/minute.
3. Labeling: Bar code labeling (standard or custom) shall be on the side of the reel opposite the sprocket holes. Refer to EIA
Standards 556 and 624.
