The T550 axial-leaded and T555 surface-mount Polymer Hermetically Sealed (PHS) devices are tantalum capacitors featuring a tantalum anode and Ta₂O₅ dielectric. A conductive organic polymer replaces the conventionally used MnO₂ or wet electrolyte as the cathode plate of the capacitor. This gives the capacitor very low ESR and improved capacitance retention at high frequencies and low temperatures. PHS devices also exhibit a benign failure mode, eliminating the case rupture issues that can occur with wet tantalum capacitors. Furthermore, these devices can operate at up to 80% of rated voltage with reliability comparable to or better than conventional MnO₂ or wet tantalum capacitors operating at 50% of rated voltage.

PHS capacitors also offer higher ripple current handling capability and lower ESR than wet tantalum capacitors. Due to reduced ESR and enhanced capacitance retention at higher frequencies and low temperatures, these devices provide the highest total capacitance and most cost-effective solution for high-power applications, with a package approximately 25% lighter than equivalent wet tantalum capacitors.
