The devices are claimed to provide the highest total capacitance and the most economical solution for high power applications, up to 80V, within a 25% lighter package than the equivalent wet tantalum capacitor.
T550/T551 series capacitors exhibit a benign failure mode which is said to eliminate the case breach that can occur in wet tantalum types. Additionally, the parts may be operated at voltages up to 80% of rated voltage with equivalent or better reliability than traditional MnO2 or wet tantalum capacitors. T550/T551 Series PHS are also said to benefit from higher ripple current handling capability and a lower ESR range than wet tantalums.
The PGS capacitors are available in MIL–PRF–39006/22/25/30/31 case sizes and are suitable for use in harsh environments and 48V applications.
