Tantalum Surface Mount Capacitors – High Reliability T428 Series High Volumetric Efficiency Facedown Commercial Off-The-Shelf (COTS) MnO2 Overview The KEMET T428 Series was developed to provide the volumetric efficiency of a conformally coated capacitor in a pickand-place friendly molded package. The planerity of the molded package eliminates the “drops” associated with the conformally coated tantalum surface mount devices. This new package design offers the highest CV/cc of any molded leadframe product. In addition, the facedown construction offers higher power ratings per cc. The robust design features and testing protocol make this part suitable for application in the telecommunications, industrial, military and aerospace markets.

Permissible AC ripple voltage which 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. See the Reverse Voltage section for allowable limits. The maximum power dissipation by case size can be determined using the table at right. The maximum power dissipation rating stated in the table must be reduced with increasing environmental operating temperatures. Refer to the table below for temperature compensation requirements. KEMET Case Code EIA Case Code P 7360–38 Maximum Power Dissipation (P max) mWatts @ 25°C w/+20°C Rise 325 The maximum power dissipation rating must be reduced with increasing environmental operating temperatures.

The positive terminal is identified on the capacitor body by a stripe, plus in some cases a beveled edge. A small degree of transient reverse voltage is permissible for short periods per the below table. The capacitors should not be operated continuously in reverse mode, even within these limits.

Hand soldering should be performed with care due to the difficulty in process control. If performed, care should be taken to avoid contact of the soldering iron to the molded case. The iron should be used to heat the solder pad, applying solder between the pad and the termination, until reflow occurs. Once reflow occurs, the iron should be removed immediately. “Wiping” the edges of a chip and heating the top surface is not recommended. During typical reflow operations, a slight darkening of the goldcolored epoxy may be observed. This slight darkening is normal and not harmful to the product. Marking permanency is not affected by this change.

Preheating of these components is recommended to avoid extreme thermal stress. KEMET's recommended profile conditions for convection and IR reflow reflect the profile conditions of the IPC/J–STD–020D standard for moisture sensitivity testing. The devices can safely withstand a maximum of three reflow passes at these conditions. tP Maximum Ramp Up Rate = 3ºC/seconds Maximum Ramp Down Rate = 6ºC/seconds tL Tsmax Tsmin 25 tS 25ºC to Peak Time Storage Tantalum chip capacitors should be stored in normal working environments. While the chips 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 40ºC 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 chip stock should be used promptly, preferably within three years of receipt. © KEMET Electronics Corporation • P.O.
