Tantalum Surface Mount Capacitors – Standard Tantalum T491 Industrial Grade MnO 2 Reverse Voltage Solid tantalum capacitors are polar devices and may be permanently damaged or destroyed if connected with the wrong polarity. 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 table. The capacitors should not be operated continuously in reverse mode, even within these limits.

This slight darkening is T s normal and not harmful to the product. Marking permanency is not affected by this change. 25 25°C 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 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, chip stock should be used promptly, preferably within three years of receipt. © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard T2005_T491 • 2/17/2020 1166 Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com
