KEMET Organic Capacitor (KO-CAP) – Low ESR
T520 Series Polymer Tantalum
Overview
The KEMET Organic Capacitor (KO-CAP) is a tantalum
capacitor with a Ta anode and Ta2O5 dielectric. A conductive
organic polymer replaces the traditionally used MnO2 as the
cathode plate of the capacitor. This results in very low ESR and
improved capacitance retention at high frequency. The KO-
CAP also exhibits a benign failure mode which eliminates the
ignition failures that can occur in standard MnO2 tantalum types.
KO-CAPs may also be operated at steady state voltages up to
90% of rated voltage for part types with rated voltages of ≤ 10
volts and up to 80% of rated voltage for part types > 10 volts
with equivalent or better reliability than traditional MnO2 tantalum
capacitors operated at 50% of rated voltage.
The T520 Series KO-CAP Low ESR Polymer captures the
best features of multilayer ceramic (low ESR, high frequency
capacitance retention), aluminum electrolytic (higher capacitance,
benign failure mode), and proven solid tantalum technology
(volumetric efficiency, surface mount capability, extremely long
life). The T520 can reduce component counts, eliminate through-
hole assembly by replacing cumbersome leaded aluminum
capacitors, and offer a cost-effective and space-saving solution.
Benefits
• Extremely low ESR
• -55°C to 105°C operating temperature range
• Polymer cathode technology
• High frequency capacitance retention
• Non-ignition failure mode
• Capacitance up to 1,500 µF
• 100% accelerated steady state aging
• 100% surge current tested
• Taped and reeled per EIA 481
• Volumetric efficiency
• Self-healing mechanism
• EIA standard case sizes
• Halogen Free Epoxy
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 solder.

(1) To complete KEMET part number, insert T = 100% Matte Tin (Sn) Plated,H = Standard Solder coated (SnPb 5% Pb minimum), P = Ni-Pd-Au Plated, N = Non-
Magnetic 100% Tin (Sn), M = Non-Magnetic (SnPb).Refer to Ordering Information for additional detail.
Also available on large (13 inch) reels. Add 7280 to the end of the part number.
Higher voltage ratings and tighter tolerance product including ESR may be substituted within the same size at KEMET's option. Voltage substitutions will be marked
with the higher voltage rating. Substitutions can include better than series.

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 desity 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).
1 Height of these chips may create problems in wave soldering.
2 Land pattern geometry is too small for silkscreen outline.
