TANTALUM DIPPED / RADIAL - POLAR
T350, T351, T352, T353, T354, T355 & T356 SERIES “ULTRADIP II”
The KEMET ‘UltraDip II’ Capacitors offer the designer of quality
instruments and entertainment systems the widely recognized
advantages inherent in solid tantalum capacitors at competitive
prices.
The ‘UltraDip II’ Series, miniature dipped solid tantalum capacitors,
provide the designer with the advantage of compactness plus low
leakage and low DF performance characteristics for filtering,
bypassing, coupling, blocking and RC timing circuits. This series fea-
tures a capacitance range from 0.1 to 680 microfarads at voltages
from 3 to 50 VDC. ‘UltraDip II’ capacitors utilize the same sophisti-
cated materials and processes which have advanced KEMET
Electronics Corporation to the leadership position in solid tantalum
capacitors.
The plastic case provides a tough barrier coating and maintains pre-
cision of lead wire spacing within ±0.015 inch. The gold color epoxy
utilized permits Laser marking with outstanding permanency and
legibility. All case sizes are printed with capacitance, voltage, polar-
ity and vendor identification.
Solid tantalum devices exhibit no degradation failure mode during
shelf storage and show a constantly decreasing failure rate (i.e.,
absence of wearout mechanism) during life tests.
The ‘UltraDip II’ Series provides self-insulating cases which are
resistant to shock and vibration. These capacitors exhibit low DCL,
ESR and Impedance and have excellent temperature stability.

(1) To complete KEMET Part Number, insert Series Designation as follows: “0” = T350, “1” = T351, “2” = T352, “3” = T353, “4” = T354, “5” = T355, “6” = T356.
(2) To complete KEMET Part Number, insert only Series Designation as follows: “0” = T350, “3” = T353, “4” = T354, “6” = T356.
(3) To complete KEMET Part Number, insert Capacitance Tolerance Symbol: “M” = ±20%, “K” = ±10%.
Bold Face
print indicates popular values.
NOTE: Higher voltage and better capacitance tolerance product may be substituted for an order within the same case size at KEMET’s option.
