Tantalum Polymer Capacitors – Hermetically Sealed T550 Axial & T555 Surface Mount 105°C Overview The T550 axial leaded and T555 surface mount polymer hermetically sealed (PHS) devices are tantalum capacitors with 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. The PHS device also exhibits a benign failure mode, which eliminates the case breach that can occur in wet tantalum capacitors. Additionally, this part 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. PHS capacitors 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 +105°C • DLA drawing 13030 qualified parts available • Polymer cathode technology • Extremely low ESR • High frequency and low temperature capacitance retention • 100% constant voltage conditioning (240 hours) • 100% surge current tested • Volumetrically efficient • Non-ignition failure mode • Approximately 25% lighter than equivalent wet tantalum • T550 case dimensions equivalent to MIL–PRF–39006/22/25/30/31 • T555 surface mount design (see dimensions diagram) Applications Typical applications include high voltage power management, such as buck/boost converters, filtering, hold-up capacitors, and other high ripple current applications.

Permissible AC ripple voltage that may be applied is limited by two criteria: 1. The positive peak AC voltage plus the DC bias voltage, if any, must not exceed the DC voltage rating of the capacitor. 2. The negative peak AC voltage in combination with bias voltage, if any, must not exceed the allowable limits specified for reverse voltage. The maximum power dissipation by case size can be determined using the below left table. The maximum power dissipation rating stated in the table must be reduced with increasing environmental operating temperatures. Refer to the below right table for temperature compensation requirements.

Mounting WARNING: T555/T556 MUST BE HAND SOLDERED. THE USE OF STANDARD SMD PROCESSES FOR BOARD MOUNT WILL CAUSE IRREVERSIBLE DAMAGE TO THIS PRODUCT. T555 SMD In hand-soldering tantalum polymer SMT capacitors, a manufacturer can utilize two (2) soldering methodologies that include pre-heating or not pre-heating the capacitors. KEMET recommends utilizing a pre-heating technique. However, due to the large temperature gradient between the capacitors and the tip of the soldering iron, take extreme caution in this process. The thermal stresses from the large thermal gradients and the propensity of the operator touching the tip of the soldering iron to the device can lead to mechanical and/or electrical damage. When manually soldering, it is important the soldering process be carefully monitored and carried out so that the temperature gradient falls within the recommended conditions above (profile). © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com T2059_T550 • 10/19/2020 12 Tantalum Polymer Capacitors – Hermetically Sealed T550 Axial & T555 Surface Mount 105°C Mounting cont. Process 1 (with preheating) 1) Utilize 1.0 mm thread eutectic solder with soldering flux in the core. Either a rosin-based or non-activated flux is recommended. 2) The capacitors shall be pre-heated so that the temperature gradient between the devices and the tip of the soldering iron is Delta T < = 120°C or below. 3) The temperature of the solder iron tip should not exceed 270°C. 4) The required amount of solder shall be melted in advance on the soldering tip. 5) After soldering, the capacitors shall be cooled gradually at room ambient temperature. Forced air cooling is not recommended. Process 2 (without preheating) 1) Soldering iron tip shall never directly touch the termination egress or the case body of the capacitors. 2) Lands are sufficiently pre-heated with a soldering iron tip before sliding the soldering iron tip to the terminal electrode of the capacitor for soldering. Reference Condition Case Size All Temperature of soldering iron 270°C Wattage 20 W maximum Shape of soldering iron 3 mm maximum Soldering time with soldering iron 3 seconds maximum T550 Through-Hole All encased capacitors will pass the resistance to soldering heat test of MIL-STD-202, Method 210, Condition C. This test simulates wave solder of topside board mount product. This demonstration of resistance to solder heat is in accordance with what is believed to be the industry standard. More severe treatment must be considered reflective of an improper soldering process. The above figure is a recommended solder wave profile for both axial and radial leaded solid tantalum capacitors. Additional mounting recommendations (SMD and Through-Hole): In order to increase the board mount integrity of KEMET's Polymer Hermetic Sealed (SMD or TH version) relative to mechanical shock and vibration, KEMET recommends the use of an adhesive between the component and the PCB.

While the capacitors themselves are quite robust in other environments, solderability will be degraded by exposure to high temperatures, high humidity, corrosive atmospheres, and long term storage. In addition, packaging materials will be degraded by high temperature – reels may soften or warp and tape peel force may increase. KEMET recommends that maximum storage temperature not exceed 40°C and maximum storage humidity not exceed 60% relative humidity. Temperature fluctuations should be minimized to avoid condensation on the parts and atmospheres should be free of chlorine and sulphur bearing compounds. For optimized solderability capacitors stock should be used promptly, preferably within three years of receipt.
