Tantalum Surface Mount Capacitors – Standard Tantalum

Reverse Voltage

Solid tantalum capacitors are polar devices and may be permanently damaged or destroyed if connected with the wrong polarity. The

positiveterminalisidentifiedonthecapacitorbodybyastripeplusinsomecasesabevelededge.Asmalldegreeoftransientreverse

voltage is permissible for short periods per the table. The capacitors should not be operated continuously in reverse mode, even within

these limits.

Density Level A: For low-density product applications. Recommended for wave solder applications and provides a wider process window for reflow solder processes.

Density Level B: For products with a moderate level of component density. Provides a robust solder attachment condition for reflow solder processes.

Density Level C: For high component desity product applications. Before adapting the minimum land pattern variations the user should perform qualification

testing based on the conditions outlined in IPC standard 7351 (IPC–7351).

¹ Height of these chips may create problems in wave soldering.
