T330 Series

KEMET T330 Series, polar-type, radial lead rectangular Precision

Molded Tantalum (PMT) capacitors are primarily designed for appli-

cations that demand full use of the premium space available in print-

ed circuitry and high density packaging. Compact, space saving

T330 Series capacitors provide superior packing factor and space

utilization compared with tubular units of the same microcoulomb

(CV) rating.

T330 Series capacitors employ a rectangular sintered, dry tantalum

anode, transfer molded in precision dies with a high impact resistant

plastic having excellent electrical, physical, and moisture resistant

properties. All cases utilize gold color plastic which permits laser

marking with outstanding permanency and legibility. The polarity is

indicated by a + sign permanently marked on the case. The radius on

the two vertical edges at the positive end of B, C, and D Cases can

be used as a sensing dimension for automatic insertion processes.

The location of the standoffs may serve a similar sensing function for

the A Case. These standoffs, located in the base of all case sizes,

provide vents for air circulation and also allow easy removal of flux

residues from leadwire and circuit board solder joints.

T330 Series capacitors are highly reliable and exhibit performance

characteristics typical of military test standards. They are available

in capacitance values ranging from 0.1 to 220 microfarads in ±20,

±10, ±5% tolerance levels, and in working voltages from 6 to 50

volts. At 85°C the capacitors will operate continuously at full rated

voltage. They are rated to 125°C when operated at 2/3 of nameplate

voltage. In addition, they feature exceptionally low DC leakage and

Dissipation Factor characteristics.

They are ideal for bypass, coupling, and timing applications in com-

puters, military ordinance, industrial, entertainment, and consumer

electronic equipment.

PERFORMANCE CHARACTERISTICS

T340 Series

The compact space saving T340 Series is transfer molded in preci-

sion dies with a high impact resistant plastic having excellent elec-

trical, physical, and moisture resistant properties. The gold color

plastic case utilized permits laser marking with outstanding perma-

nency and legibility.

Marking is provided on the top of the case to allow visual inspection

for proper polarity and placement after insertion. In addition, positive

polarity identification is achieved by an easily recognized molded

radius on the positive end of the case. This physical polarity identifi-

cation is readily observed after capacitor placement as a further aid

to the top marking in prevention of possible reverse insertion.

Standoffs, located in the base of all case sizes, provide vents for air

circulation and also allow easy removal of flux residues from lead-

wire and circuit board solder joints. With very low impedance and

ESR values, the T340 Series features exceptionally low DC leakage

and DF characteristics. The T340 Series is available in standard

±20%; ±10%; ±5% (special order) capacitance tolerance.

T340 Series capacitors are highly reliable and exhibit performance

characteristics typical of military test standards.
