Tantalum Surface Mount Capacitors â Standard Tantalum
T491 Industrial Grade MnO2 Series
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.

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 (IPCâ7351).
¹ Height of these chips may create problems in wave soldering.
2 Land pattern geometry is too small for silkscreen outline.
