1 Tantalum Through-Hole apacitors Hermetically Sealed Overview The hermetically sealed T252 Series solid tantalum capacitors offer high capacitance-to-volume ratios and are offered in standard MIL style A,,, and cases. They meet or exceed the environmental and mechanical requirements of MIL esigned to operate from 55 to +125, The T252 Series exhibits exceptionally low leakage, dissipation factor and impedance characteristics. They are ideal for coupling, bypass, filtering and timing circuits, and are excellent substitutes for wet tantalum's in low voltage applications. These parts are available in style SR33 (T252 Series) per MIL PRF 39003/06 in capacitance value of 1.2 µf to 1000 µf and working voltages pf 6 V to 50 V. enefits Taped and reeled per EIA Specification RS 296 Marking per MIL ST 1285 Qualified to MIL PRF (SR33 Style) Failure rate options: Graded,, and G Exponential - M, P, R, and S* apacitance values of 1.2 μf to 1000 μf Tolerances of ±10% and ±20% Voltage rating of 6 50 V Operating temperature range of 55 to +125 ase sizes: A,,, *Failure rates apply to military products only lick image above for interactive 3 content Open PF in Adobe Reader for full functionality Applications These capacitors are ideal for coupling, bypass, filtering and timing circuits, and are excellent substitutes for wet tantalum's in low voltage applications.

6 Ripple urrent/ripple Voltage Permissible A ripple voltage is related to the ESR of the capacitor and the power dissipation capabilities of a particular case size. Thermal capacities for the various case sizes have been determined empirically and are listed below. Temperature ompensation Multipliers for Power issipation T 25 T 85 T T= Environmental Temperature Permissible A ripple current can be determined by the following: I(max) = Z P max/r P max = maximum watts R = ESR at specified frequency (ohms) I = rms ripple current (amperes) Z = capacitor impedance in ohms at the specified frequency ase Size Power issipation (P max) T2XX A Power issipation: 25 Ambient KEMET Electronics orporation KEMET Tower One East roward oulevard T2035_T252_AXIAL 1/15/

The capacitors should not be operated continuously in reverse mode, even within these limits. Temperature Pecentage of Voltage Mounting All encased capacitors will pass the Resistance to Soldering Heat Test of MIL ST 202, Method 210, ondition. 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.

9 Storage Tantalum hermetically sealed capacitors should be stored in normal working environments. 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 40º 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.
