POLYMER TANTALUM CHIP CAPACITORS

COMPONENT PERFORMANCE CHARACTERISTICS

Introduction

4. Voltage Ratings

KEMET has developed a new type of tantalum capacitor

that replaces the solid manganese dioxide electrode with

a solid conductive polymer. This product is named the

KO-CAP for KEMET Organic Capacitor. The basic fami-

lies are the T520 and T530 series. A separate detail of

performance characteristics is presented here as there

are some differences between the polymer tantalums and

the standard MnO2 types. Like all KEMET tantalum

chips, these series are 100% screened for all electrical

parameters: Capacitance @ 120 Hz, Dissipation Factor

(DF) @ 120 Hz, ESR @ 100 kHZ and DC Leakage. It is

also 100% surge current tested at full rated voltage

through a low impedance circuit. The advantages of the

polymer include very low ESR and elimination of the

potentially catastrophic failure mode that may occur with

standard tantalum capacitors in a high surge current

application. Although the natural KO-CAP series failure

mechanism is a short circuit, it does not exhibit an explo-

sive failure mode.

• 2V-16V DC Rated Voltage

This is the maximum peak DC operating voltage

from -55ºC to +85ºC for continuous duty. Above

85ºC, this voltage is derated linearly to 0.8 times

the rated voltage for operation at 105ºC.

• Surge Voltage Ratings

Surge voltage is the maximum voltage to which the

part can be subjected under transient conditions

including the sum of peak AC ripple, DC bias and

any transients. Surge voltage capability is demon-

strated by application of 1000 cycles of the relevant

voltage, at 25ºC, 85ºC or 105ºC. The parts are

charged through a 33 ohm resistor for 30 seconds

and then discharged through a 33 ohm resistor for

30 seconds for each cycle.

5. Reverse Voltage Rating & Polarity

Polymer tantalum capacitors are polar devices and

may be permanently damaged or destroyed if con-

nected in the wrong polarity. The positive terminal

is identified by a laser-marked stripe and may also

include a beveled edge. These capacitors will with-

stand a small degree of transient voltage reversal

for short periods as shown in the following table.

Please note that these parts may not be operated

continuously in reverse, even within these limits.

3. Capacitance and Tolerance

• 33µF to 1500µF

• ±20% Tolerance

Capacitance is measured at 120 Hz, up to 1.0 volt rms

maximum and up to 2.5V DC maximum. DC bias caus-

es only a small reduction in capacitance, up to about

2% when full rated voltage is applied. DC bias is not

commonly used for room temperature measurements

but is more commonly used when measuring at tem-

perature extremes.

Permissible Transient Reverse Voltage

Capacitance does decrease with increasing frequency,

but not nearly as much or as quickly as standard tanta-

lums. Figure 1 compares the frequency induced cap roll-

off between the KO-CAP and traditional MnO2 types.

Capacitance also increases with increasing tempera-

ture. See s ection 12 for temperature coefficients .

6. DC Leakage Current

Because of the high conductivity of the polymer,

the KO-CAP family has higher leakage currents

than traditional MnO2 type Tantalum caps. The DC

Leakage limits at 25ºC are calculated as 0.1 x C x

V, where C is cap in µF and V is rated voltage in

Volts. Limits for all part numbers are listed in the

ratings tables.

with the capacitor.
