​ Take your high voltage management application to new levels with the KEMET T550 Polymer Hermetic Seal (PHS) Series. As compared to wet tantalums, the PHS provides up to 90% lower ESR, 40% increased ripple current capabilities, and improved capacitance retention at high frequency and low temperature. As a result, PHS offers the highest total capacitance, surpassing wet tantalum performance and, under certain operating conditions, renders it the most economical high power solution available. Solid internal construction drastically improves shock and vibration robustness, all within an approximately 25% lighter package than the equivalent wet tantalum capacitor.
