Tantalum Polymer Capacitors Hermetically Sealed T551 Axial & T556 Surface Mount 125C Overview The T551 axial leaded and T556 surface mount polymer PHS capacitors molded also offer higher ripple current hermetically sealed (PHS) devices are tantalum capacitors handling capability and a lower ESR range than wet with a Ta anode and Ta O dielectric. A conductive, tantalums. With reduced ESR and enhanced capacitance 2 5 organic polymer replaces the traditionally used MnO or retention at higher frequencies and low temperatures, these 2 wet electrolyte as the cathode plate of the capacitor. The parts provide the highest total capacitance and the most result is very low ESR and improved capacitance retention economical solution for high power applications, all within an at high frequency and low temperature. The PHS device approximately 25% lighter package than the equivalent wet also exhibits a benign failure mode, which eliminates the tantalum capacitor. case breach that can occur in wet tantalum capacitors. Additionally, the part may be operated at voltages up to 80% of rated voltage, with equivalent or better reliability or wet tantalum capacitors operated than traditional MnO 2 at 50% of rated voltage. Benefits Includes F-Tech anode, which eliminates hidden defects in the dielectric 100% simulated breakdown screening Maximum operating temperature of +125C Polymer cathode technology 0.0075 CV (A) at rated voltage after 5 minutes Extremely low ESR High frequency and low temperature capacitance retention 100% constant voltage conditioning (240 hours) 100% surge current tested Volumetrically efficient Use at up to 80% of rated voltage Non-ignition failure mode Approximately 25% lighter than equivalent wet tantalum T551 case dimensions equivalent to MIL-PRF-39006/22/25/30/31 T556 surface mount design (see dimensions diagram) Built Into Tomorrow KEMET Electronics Corporation KEMET Tower One East Broward Boulevard T2072 T551 10/21/2020 1 Fort Lauderdale, FL 33301 USA 954-766-2800 www.kemet.comTantalum Polymer Capacitors Hermetically Sealed T551 Axial & T556 Surface Mount 125C Applications Typical applications include high voltage power management, such as buck/boost converters, filtering, hold-up capacitors, and other high ripple current applications.
