POLYMER TERMINATION
NOVACAP offers polymer terminated capacitors, which are able to accommodate a significantly increased degree of board flex-
ure compared with standard terminated capacitors. These devices will afford a wider process window, increased safety margin,
and substantially reduce the cracks from mechanical stress.
1
These devices require no change to the assembly process, equip-
ment set up, or storage procedures. The polymer terminated capacitors are offered in all dielectrics but the most significant ben-
efit occurs with X7R and Y5V dielectrics. All combination of voltage ratings and capacitance offerings listed in the catalog for case
sizes 0603 through 3640 are available.

The user must not assume use of the polymer terminated capacitors will totally eliminate mechanical cracking. Good process controls are still required for this
objective to be achieved.
