Terminations

PROTAVIC termination products protect against cracks that can arise during surface mounted device (SMD) assembly from picking and placing, soldering and handling all the way through to the final tests of the circuit board (PCBA).

By providing flexibility that dramatically reduces stress cracking, the terminations developed by PROTAVIC greatly reduce the possibility of capacitor failure.

Some examples are listed in the table below.
