Overview
The KEMET T550 Series Polymer Hermetic Seal (PHS) is a
tantalum capacitor with a Ta anode and Ta

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.
