The KEMET Organic Capacitor (KO-CAP) is a solid electrolytic
capacitor with a conductive polymer cathode capable of
delivering very low ESR and improved capacitance retention at
high frequencies. KO-CAP combines the low ESR of multilayer
ceramic, the high capacitance of aluminum electrolytic and the
package. Unlike liquid electrolyte-based capacitors, KO-CAP has
a very long operational life and high ripple current capabilities.
Benets
• Extremely low ESR
• Volumetricallyefcient
• High frequency capacitance retention
• 100% accelerated steady state aging
• 100% surge current tested
• EIA standard case sizes
• Halogen-Free Epoxy/RoHS Compliant
The T520 Low ESR Polymer Electrolytic provides the widest range
of voltage, capacitance and case size options in the KO-CAP
family. Suitable for general purpose DC applications up to 12.8
volts, the T520 is ideal for DC-to-DC converters, bulk decoupling
and hold-up.
Applications
Typical applications include DC/DC converters, notebook PCs, portable electronics, telecommunications (mobile phone and base
station), displays, SSD, HDD and USB.
Environmental Compliance
RoHS Compliant (6/6) according to Directive 2002/95/EC when ordered with 100% Sn , Ni-Pd-Au or Non-magnetic 100% Sn solder.
Notes: (Ref) – Dimensions provided for reference only. For low prole cases, no dimensions are provided for B, P or R because these cases do not have a bevel or a notch.

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
reverse voltage. See the Reverse Voltage section for allowable
limits.
The maximum power dissipation by case size can be determined
using the table at right. The maximum power dissipation rating
stated in the table must be reduced with increasing environmental
operating temperatures. Refer to the table below for temperature
compensation requirements.

The maximum power dissipation rating must be reduced with increasing
environmental operating temperatures. Refer to the Temperature
Compensation Multiplier table for details.
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) = Z √P max/R
I = rms ripple current (amperes)
E = rms ripple voltage (volts)
P max = maximum power dissipation(watts)

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

Although KEMET designs and manufactures its products to the most stringent quality and safety standards, given the current state of the art, isolated component failures may still
occur. Accordingly, customer applications which require a high degree of reliability or safety should employ suitable designs or other safeguards (such as installation of protective
circuitry or redundancies) in order to ensure that the failure of an electrical component does not result in a risk of personal injury or property damage.
Although all product–related warnings, cautions and notes must be observed, the customer should not assume that all safety measures are indicted or that other measures may not
be required.
