Tantalum Polymer Capacitors – Hermetically Sealed

T551 Axial & T556 Surface Mount 125°C

Overview

The T551 axial leaded and T556 surface mount polymer

hermetically sealed (PHS) devices are tantalum capacitors

with a Ta anode and Ta

dielectric. A conductive,

organic polymer replaces the traditionally used MnO

wet electrolyte as the cathode plate of the capacitor. The

result is very low ESR and improved capacitance retention

at high frequency and low temperature. The PHS device

also exhibits a benign failure mode, which eliminates the

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

than traditional MnO

or wet tantalum capacitors operated

at 50% of rated voltage.

PHS capacitors molded also offer higher ripple current

handling capability and a lower ESR range than wet

tantalums. With reduced ESR and enhanced capacitance

retention at higher frequencies and low temperatures, these

parts provide 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.

Benefits

• Includes F-Tech anode, which eliminates hidden defects in

the dielectric

• 100% simulated breakdown screening

• Maximum operating temperature of +125°C

• Polymer cathode technology

• ≤ 0.0075 CV (µA) 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)
