Tantalum Through-Hole Capacitors – Hermetically Sealed
T550 Axial Polymer Hermetic Seal (PHS) 105°C
and DLA Series
Overview
The KEMET T550 Series Polymer Hermetic Seal (PHS)
is a tantalum capacitor with a Ta anode and Ta
2
O
5
dielectric. A conductive organic polymer replaces the
traditionally used MnO
2
or wet electrolyte as the cathode
plate of the capacitor. This results in very low ESR and
improved capacitance retention at high frequency and low
temperature. The T550 Series PHS also exhibits a benign
failure mode which eliminates the case breach that can
occur in wet tantalum types. Additionally, this part may
be operated at voltages up to 80% of rated voltage with
equivalent or better reliability than traditional MnO
2
or wet
tantalum capacitors operated at 50% of rated voltage.
T550 Series PHS also offers higher ripple current handling
capability and a lower ESR range than wet tantalums.
With reduced ESR and enhanced capacitance retention at
higher frequencies and low temperatures, the T550 Series
PHS provides the highest total capacitance and the most
economical solution for high power applications, all within an
approximately 25% lighter package than the equivalent wet
tantalum capacitor.
