KEMET T551 Series PHS Polymer Capacitors

Product Announcement from Mouser Electronics, Inc.


KEMET T551 Series PHS Polymer Capacitors feature a Ta anode and Ta2O5 dielectric. A conductive organic polymer replaces the traditionally used MnO2 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. KEMET T551 Series PHS (Polymer Hermetic Seal) also exhibits a benign failure mode, which eliminates the case breach that can occur in wet tantalum types. T551 may be operated at voltages up to 80% of rated voltage with equivalent or better reliability than traditional MnO2 or wet tantalum capacitors operated at 50% of rated voltage. T551 Series PHS also offers higher ripple current handling capability and a lower ESR range than wet tantalums. T551 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.
