Tantalum Through-Hole Capacitors – Molded Radial
T340 Molded Radial
Overview
The compact, space-saving T340 is transfer molded in
precision, with a high impact-resistant plastic that has
excellent electrical, physical and moisture-resistant
properties. The gold color plastic case permits laser
marking with outstanding permanency 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. Additionally, this physical polarity identification is
readily observed after capacitor placement as a further aid
in the prevention of possible reverse insertion. Standoffs,
located in the base of all case sizes, provide vents for air
circulation and also to allow easy removal of flux residues
from leadwire and circuit board solder joints. With very low
impedance and ESR values, the T340 features exceptionally
low DC leakage and DF characteristics. The T340 is
available in standard ±20%, ±10% and ±5% (special order)
capacitance tolerance. T340 capacitors are highly reliable
and exhibit performance characteristics typical of military
test standards.
Benefits
• Taped and reeled per EIA Specification RS-468
• Laser-marked case
