TANTALUM MOLDED / RADIAL
T330/T340 SERIES - PRECISION MOLDED — RADIAL LEAD — POLAR TYPE
T330 Series
KEMET T330 Series, polar-type, radial lead rectangular Precision
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.
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 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.
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.
They are ideal for bypass, coupling, and timing applications in com-
puters, military ordinance, industrial, entertainment, and consumer
electronic equipment.
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.
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.
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.
T340 Series capacitors are highly reliable and exhibit performance
characteristics typical of military test standards.
