Reverse Voltage

Although these are polar capacitors, some degree of transient voltage reversal is permissible, as seen below.

The capacitors should not be operated continuously in reverse mode, even within these limits.

Mounting

All encased capacitors will pass the Resistance to Soldering Heat Test of MIL–STD–202, Method 210, Condition C. 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.
