Aluminum Organic Capacitor (AO-CAP)

A720 Polymer Aluminum

Reverse Voltage

Polymer aluminum capacitors are polar devices and may be permanently damaged or destroyed if connected in the wrong

polarity. These devices will withstand a certain degree of transient voltage reversal for short periods, as shown in the below

table. Please note that these parts may not be operated continuously in reverse, 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 density 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.
